Description

TECHNICAL FIELD

[0001] The present application relates to the field of construction control, and particularly relates to a construction control method and system for preventing micro-vibration of a radiation-proof structure foundation. BACKGROUND

[0002] Taking a large scientific device, i.e., a synchronous radiation light source accelerator, as an example, the control requirement for displacement in each direction is very strict, and is usually required to be in nanometer level. In order to achieve the above-mentioned target, it is necessary to control various vibration sources during site selection and construction of the light source, so as to ensure that the displacement in each direction meets the requirement in nanometer level after the light source is finally built.

[0003] At present, the commonly used vibration control construction method during construction of the light source usually first detects the vibration characteristics of the site, obtains the acceleration of the site pulsation, then designs the structure according to the control target, and analyzes the vibration response of the designed structure, and finally obtains the acceleration of the structure by measuring the vibration response of the structure, so as to verify the vibration control effect.

[0004] When the site geology is simple, such as simple soft soil or hard soil, the acceleration of the ground pulsation can be accurately measured in the related technology, and the subsequent vibration analysis and construction are also relatively accurate, and meet the vibration control requirement. However, when the site geology is complex, the acceleration of the ground pulsation in the complex cannot be accurately measured, which will lead to that the subsequent construction cannot meet the strict vibration control requirement. SUMMARY

[0005] The present application provides a construction control method and system for preventing micro-vibration of a radiation-proof structure foundation, which is used for guiding the construction under the condition that the site geology is complex, and ensuring that the vibration control is accurate and meets the requirement.

[0006] In a first aspect, the application provides a construction control method for preventing radiation structure from micro-vibration, applied to a construction control system, comprising: extracting a target building structure from construction drawings, dividing the target building structure into N structure blocks connected in sequence; obtaining initial construction parameters, taking the first structure block as a preceding block, taking the initial construction parameters as current construction parameters, and constructing the preceding block according to the current construction parameters; testing the vibration displacement amplitude of the raft of the preceding block, and determining whether the vibration displacement amplitude is not higher than a micro-vibration control target; if the vibration displacement amplitude is not higher than the micro-vibration control target, taking the current construction parameters as target construction parameters, and constructing each block after the preceding block according to the target construction parameters; if the vibration displacement amplitude is higher than the micro-vibration control target, adjusting the current construction parameters to test construction parameters; the test construction parameters are different from the current construction parameters; constructing the subsequent block according to the test construction parameters; the subsequent block is the next block of the preceding block; taking the combination of the preceding block and the subsequent block as the preceding block, and taking the test construction parameters as the current construction parameters; repeating the steps of testing the vibration displacement amplitude of the raft of the preceding block and determining whether the vibration displacement amplitude is not higher than the micro-vibration control target.

[0007] In the above embodiment, by extracting the target building structure and dividing it into multiple structure blocks, and then optimizing the construction parameters and testing the vibration in a zoned and progressive manner, the uncertainty caused by complex site geological conditions can be effectively addressed, making the vibration reduction measures more accurate and effective. Dynamic response to early construction feedback can be achieved, and the subsequent construction parameters can be optimized and adjusted in real time, which can significantly improve the overall vibration resistance performance of the building structure and ensure that the micro-vibration control precision meets the high standard use requirements.

[0008] In combination with some embodiments of the first aspect, in some embodiments, if the vibration displacement amplitude is higher than the micro-vibration control target, the current construction parameters are adjusted to test construction parameters, specifically including: if the vibration displacement amplitude is higher than the micro-vibration control target, determining the current vibration frequency corresponding to the current construction parameters according to the displacement frequency spectrum of the preceding block; increasing the current vibration frequency by a preset frequency value to obtain an expected vibration frequency; and binding the expected vibration frequency to the corresponding test construction parameters.

[0009] In the above embodiment, the construction control system can accurately determine the actual vibration characteristics of the structure under the current construction parameters by collecting raft vibration data and combining frequency spectrum analysis, predict the required structure stiffness under the expected frequency using structure dynamics theory, and match the corresponding pile foundation construction parameters, so as to quantitatively decompose the vibration control target under the premise of ensuring the feasibility of engineering implementation, and make the dynamic optimization in the construction process more targeted.

[0010] In some embodiments of the first aspect, before the step of increasing the current vibration frequency by a preset frequency value to obtain an expected vibration frequency, the method further comprises: collecting a power spectrum of a site where the target building is located; determining a dominant frequency of the ground microseism according to the power spectrum; and determining the preset frequency value based on the dominant frequency and the current vibration frequency.

[0011] In the above embodiments, the construction control system comprehensively masters the dynamic characteristics of the environmental excitation through the survey and data analysis of the geological conditions of the site, and accurately finds out the weak frequency band prone to resonance in combination with the inherent frequency test of the structure itself. Based on this, a targeted frequency adjustment scheme is customized to maximize the avoidance of resonance risks while ensuring the safety of the structure.

[0012] In some embodiments of the first aspect, the post-block is constructed with the test construction parameter, specifically comprising: determining an expected vibration frequency bound with the test construction parameter, and obtaining a pre-equivalent mass of the pre-block; determining an expected frequency range corresponding to the expected vibration frequency; obtaining a number of raft piles for construction of the post-block, so that the overall equivalent mass and the overall equivalent stiffness satisfy the calculation result of the pre-design calculation formula within the expected frequency range; the overall equivalent mass is the sum of the pre-equivalent mass and the post-equivalent mass, the post-equivalent mass is determined by the number of raft piles, and the overall equivalent stiffness is determined by the number of raft piles; and the post-block is constructed with the post-equivalent mass and the number of raft piles.

[0013] In the above embodiments, the construction control system takes the number of raft piles as a key control variable for adjusting the mass and stiffness and then adjusting the frequency of the structure. By matching the dynamic characteristic responses of the structure under different numbers of piles, an optimal balance is sought between the frequency control target and the cost constraint. Under the premise of ensuring the safety of the structure and meeting the design specifications, feasible schemes for controlling the frequency of the structure are quantitatively explored to guide key construction links with refined parameter analysis, thereby improving the scientificity and operability of vibration control. At the same time, by optimizing the economic pile type arrangement within the frequency range, the amount of foundation is maximally reduced, thereby ensuring the vibration reduction effect while taking into account the reasonableness of the engineering cost.

[0014] In some embodiments of the first aspect, the pre-design calculation formula is: wherein f i is the expected vibration frequency, k i is the overall equivalent stiffness, and m i is the overall equivalent mass.

[0015] In the above embodiment, the construction control system adopts the single mass system inherent vibration frequency calculation formula in theoretical mechanics to establish an explicit expression of the frequency and the mass and stiffness parameters, which can maximize the problem simplification and highlight the main contradiction. Taking the overall equivalent mass and stiffness of the structure as control variables can reduce local detail interference, facilitate systematic vibration control measures, and facilitate engineering practice.

[0016] In combination with some embodiments of the first aspect, in some embodiments, the raft pile number of the post-positioned block construction is obtained, so that the overall equivalent mass and the overall equivalent stiffness satisfy the calculation result of the pre-design calculation formula within the expected frequency range, specifically including: determining the corresponding pile number estimation range according to the expected frequency range; calculating the overall equivalent mass and the overall equivalent stiffness corresponding to the raft pile number based on the raft pile number in the pile number estimation range selected by the engineer; determining whether the calculation result of the overall equivalent mass and the overall equivalent stiffness substituted into the pre-design calculation formula is within the expected frequency range; if not, prompting the engineer to reselect the raft pile number.

[0017] In the above embodiment, the construction control system first locks a reasonable pile foundation arrangement interval based on the engineering site and the structure design conditions, and uses the experience rules in the expert knowledge base to quickly lock a reasonable pile foundation arrangement interval. On this basis, through interaction with the engineer, the damping effect, construction convenience, cost economy and other factors are comprehensively considered to guide the engineer to dynamically adjust and optimize the pile foundation scheme in the selected interval. Both the advantages of computer analysis of massive data are exerted to automatically select feasible schemes and provide judgment basis for manual decision making, and the professional experience and comprehensive weighing ability of the engineer are utilized to give the engineer the initiative to judge and choose, so that the design efficiency and reliability of the pile type scheme are improved through man-machine collaborative optimization.

[0018] In combination with some embodiments of the first aspect, in some embodiments, before the step of extracting the target building structure in the construction drawing and dividing the target building structure into N structure blocks connected in front and back order, the method further includes: obtaining the construction parameters of the historical construction buildings input by the engineer and the corresponding construction quality evaluation index; extracting the mapping relationship between the construction parameters and the construction quality evaluation index to obtain the recommended value range of each construction parameter; determining the construction parameter reference value of the recommended value range based on the selection operation of the engineer.

[0019] In the above embodiment, the construction control system analyzes the construction scheme and actual quality performance of the historical similar projects through intelligent analysis to establish the internal mapping relationship, which can quickly lock the reasonable value interval of each construction parameter, avoid the limitations and blindness of subjective experience judgment. The parameter optimization library formed thereby can provide more optimization space and flexibility for engineering design, ensure engineering quality, also consider economic rationality, and realize technical collaboration of design and construction integration.

[0020] In a second aspect, the embodiments of the present application provide a construction control system, comprising: one or more processors and a memory; the memory is coupled to the one or more processors, and the memory is configured to store computer program codes, the computer program codes comprising computer instructions, and the one or more processors are configured to invoke the computer instructions to cause the construction control system to perform the method described in the first aspect and any possible implementation manner of the first aspect.

[0021] In a third aspect, the embodiments of the present application provide a computer program product comprising instructions which, when executed on a construction control system, cause the construction control system to perform the method described in the first aspect and any possible implementation manner of the first aspect.

[0022] In a fourth aspect, the embodiments of the present application provide a computer-readable storage medium comprising instructions which, when executed on a construction control system, cause the construction control system to perform the method described in the first aspect and any possible implementation manner of the first aspect.

[0023] It can be understood that the construction control system provided in the second aspect, the computer program product provided in the third aspect, and the computer storage medium provided in the fourth aspect are all used to execute the method provided by the embodiments of the present application. Therefore, the beneficial effects that can be achieved are referred to the beneficial effects in the corresponding method, which will not be described here.

[0024] The one or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0025] 1. Since the method of dividing the overall building structure into multiple sub-blocks for separate construction, testing and optimization is adopted, personalized vibration control can be implemented for different block conditions, effectively solving the problem of lack of pertinence and flexibility of overall structure analysis and vibration reduction measures in the related art, and thus realizing precise vibration control under complex geological conditions.

[0026] 2. Since the progressive optimization strategy of adjusting the construction parameters of the subsequent blocks on the basis of the feedback of the front block is adopted, the key data of the early vibration test can be fully absorbed and utilized, and the best vibration reduction effect is approached through continuous optimization during construction, effectively solving the problem of disconnection between early survey data and late vibration response in the related art, and thus realizing intelligent vibration control with dynamic response conditions and continuous improvement.

[0027] 3. By adopting a method that combines historical experience data and presets the optimal value range of each construction parameter as the design benchmark, the advanced practices of successful cases can be fully referenced. The parameters can be optimized within the feasible range of similar projects, avoiding subjective judgment and blind attempts. This effectively solves the problems of lack of reliable design basis and easy misjudgment and deviation in related technologies, and thus realizes intelligent parameter selection that integrates design optimization.

[0031] The terminology used in the following embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification of this application, the singular expressions “a,” “an,” “the,” “the,” and “this” are intended to include the plural expressions as well, unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used in this application refers to any or all possible combinations including one or more of the listed items.

[0032] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature, and in the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0033] To facilitate understanding, the construction scenarios in the relevant technologies are introduced below.

[0034] Taking the construction of a large-scale scientific facility, the synchrotron radiation light source, as an example, the requirements for controlling displacement in all directions are extremely stringent, typically at the nanometer level. During site selection and construction, various vibration sources need to be tested, analyzed, and controlled to ensure that all indicators are met after completion. However, due to the highly complex geological conditions of the site, coupled with the large scale and long span of the light source's civil engineering, conventional vibration reduction measures often fail to achieve the desired results.

[0035] The related art usually detects the vibration characteristics of the site first, obtains the acceleration parameters of the site pulsation, then designs the light source building structure according to the overall vibration control target, and performs vibration response analysis on the designed structure, and finally obtains the vibration mode and amplitude index of the structure by measuring the vibration response of the built structure, so as to verify the final effect of the vibration reduction design.

[0036] However, due to the difficulty in accurately measuring the acceleration data of the early site detection, the final light source construction cannot meet the stringent micro-vibration control requirements of the light source, and needs to be reworked, causing waste of cost.

[0037] The following describes a scenario in which the construction control method for micro-vibration of the anti-radiation structure foundation in the present application is used.

[0038] To solve this problem, the present application provides a construction control method for micro-vibration of the anti-radiation structure foundation. First, according to the overall planning of the light source, the structure form and functional requirements of each component unit are systematically analyzed, and on the basis of comprehensively considering factors such as geology, load, and seismic resistance, the building is divided into several basic construction blocks, and the construction sequence and connection mode of each block are clearly defined. In the actual construction process, a dynamic cycle mode of "construction-test-feedback-optimization" is adopted for each block: the first block is constructed according to the initial parameters, then the vibration control level of the block under the current construction scheme is accurately evaluated, the measured results are compared with the overall target, and optimization feedback opinions are formed; on this basis, the construction process parameters such as the number of piles of the subsequent blocks are adjusted in a timely manner, and through repeated iteration and approximation, the dynamic matching and system coordination of the vibration performance of each block are realized, and finally the overall structure is optimized in the nanometer level vibration control index.

[0039] As can be seen, by using the construction control method for micro-vibration of the anti-radiation structure foundation in the embodiments of the present application, the high-precision vibration control requirement can be realized, and the uncertainty brought by the complex geological conditions can also be effectively dealt with. Through the analysis and feedback of key data, the vibration reduction potential of the structure system is maximized, and the precise construction control of large projects such as light sources in complex environments is realized.

[0040] For ease of understanding, the method provided by the present embodiment will be described in the following flowchart in conjunction with the above scenario. Please refer to Figure 1 , which is a flowchart of the construction control method for micro-vibration of the anti-radiation structure foundation in the embodiments of the present application.

[0041] S101, extract the target building structure in the construction drawing, and divide the target building structure into N structure blocks connected in sequence.

[0042] The construction drawings refer to drawings used to guide construction in a building project, usually including building plan, elevation, section, etc., and are an important source of building structure information for the construction control system. The structure block refers to a plurality of sub-structures obtained by dividing the target building structure according to certain rules, and each sub-structure is a basic unit of construction control. N represents the total number of structure blocks obtained by dividing the target building structure.

[0043] Specifically, after obtaining the construction drawings of the project, the construction control system first needs to identify the target building structure that needs to be controlled in micro-vibration, and the identification process can be indicated by the engineer selecting and inputting data. After determining the target building structure, it is divided based on the parameter setting operation of the engineer or based on the preset average division rule. The main purpose of the block is to decompose the entire building structure into a plurality of sub-structures that can be independently controlled and tested for construction, so as to realize fine vibration control in different regions and steps.

[0044] The block usually follows several principles, and the following principles can be used as the specification for the engineer to follow or as the boundary condition for the system to program the block:

[0045] 1. The sub-structures after the block have a clear sequence in the construction sequence, so as to test the construction effect of the pre-block to guide the construction control of the subsequent block;

[0046] 2. The block granularity should be appropriate, and the vibration characteristics of each block should be relatively independent to facilitate testing and control while meeting the construction convenience;

[0047] 3. The adjacent blocks should be closely connected to avoid weak parts in the structure. The specific method of block can be flexibly handled in various ways such as planar block according to the form and stress characteristics of the building structure.

[0048] In some embodiments, the extraction and division of the target building structure can be achieved in various ways:

[0049] Optionally, the construction control system receives the manual annotation of the engineer on the building drawings, extracts the circled area as the target building structure, identifies the marked sub-regions as structure blocks, and automatically generates block numbers; the system sorts the blocks according to the construction sequence to generate a construction priority list of the blocks according to the block position relationship information.

[0050] Optionally, the construction control system automatically detects the region in the drawing that matches the preset target building feature based on image recognition technology, and extracts it as the target building structure; the system then calls the preset building block rule, such as the plane grid method, vertical layering method, etc., to automatically divide the target building structure into a plurality of polygonal blocks with regular shape and moderate size (meeting the preset boundary conditions); and according to the spatial positional relationship of the blocks, the construction sequence of the blocks is automatically inferred.

[0051] It can be understood that there are many methods for target building extraction and structure block division, and flexible processing methods such as manual, semi-automatic, and automatic can also be adopted in combination with the characteristics of specific projects and the professional experience of engineers, which are not limited here.

[0052] S102, obtain initial construction parameters, take the first structure block as the front block, and take the initial construction parameters as the current construction parameters to construct the front block.

[0053] Among them, the initial construction parameters refer to the parameter set for determining the construction scheme of the first structure block, which usually includes foundation type, foundation treatment method, foundation depth, pile type and diameter, pile length, pile spacing, etc. These parameters will directly affect the stability and vibration performance of the building structure, which will be reasonably selected by engineers according to engineering requirements and site conditions. The front block refers to the block that is currently being constructed or will be constructed in the construction sequence of multiple structure blocks, which is the object of construction control and testing. The current construction parameters refer to the parameter values that are guiding the construction of the front block, which are the initial construction parameters in the initial state.

[0054] Specifically, after completing the structure block division, the construction control system needs to determine the construction scheme of the first structure block (numbered 1) as the starting point of the entire construction process. Usually, the initial construction parameters can refer to the existing experience data of similar projects, or be determined by engineers according to the drawing content, site survey information and vibration control requirements. After obtaining the initial construction parameters, the system identifies the first structure block as the front block, and uses the initial construction parameters as the current construction parameters to guide the construction of the first block. In actual construction, necessary checking calculation or simulation needs to be carried out on the feasibility and rationality of the initial construction parameters to verify whether they meet the requirements of structural stress and deformation performance. If the checking or simulation results do not meet the requirements, the engineer needs to modify the initial construction parameters until the requirements are met.

[0055] In some embodiments, the initial construction parameters can be obtained or generated in various ways:

[0056] Optionally, the system accesses the engineering design information database, searches for historical projects similar to the current engineering design conditions, extracts corresponding construction parameters as references for the current project, receives the engineers' correction opinions on the reference construction parameters, and generates the initial construction parameter table of the current project. The system automatically associates the initial construction parameters with the first structural block to form the construction instructions.

[0057] Optionally, the system automatically extracts the load parameters, material parameters, and environmental parameters of the building from the engineering design drawings and inputs them into the structural calculation and analysis software. Through parameterized calculation and analysis, a set of structural design parameters that meet the strength, stiffness, and deformation requirements are automatically output. The system converts the structural design parameters into corresponding construction parameters to form the initial construction parameter table. At the same time, the parameter table also indicates the recommended value range of each parameter for subsequent construction parameter optimization.

[0058] It can be understood that the acquisition of initial construction parameters requires the comprehensive use of engineering design data, calculation and analysis tools, and engineers' experience data, and can be achieved through manual specification, automatic generation, and human-computer interaction, without limitation.

[0059] S103, test the vibration displacement amplitude of the raft of the pre-block, and determine whether the vibration displacement amplitude is not higher than the micro-vibration control target.

[0060] The raft refers to a commonly used slab foundation in building foundation structures, which is cast integrally by reinforced concrete and can effectively resist uneven settlement, suitable for sites with complex geological conditions. The vibration displacement amplitude refers to the amplitude peak response of a measurement point of a building structure under the action of external load or environmental factors, usually expressed in millimeters (mm), micrometers (μm), or nanometers (nm), and is an important indicator for evaluating the vibration performance of the structure. The micro-vibration control target refers to the limit requirement of the environment for the vibration level of the building, which is usually determined by factors such as the functional use of the building and the anti-vibration requirements of precision instruments and equipment, such as the micro-vibration control target of Hefei Light Source, which is controlled within 30 nm.

[0061] Specifically, after the pre-block (No. 1) is completed using the current construction parameters, the vibration response thereof needs to be tested and monitored to evaluate the vibration reduction effect of the current construction scheme. Usually, the vibration displacement of the raft foundation, which connects the upper structure and the lower foundation and has the most significant influence on the vibration performance of the entire building, is tested. During the test, a plurality of vibration sensors are pre-embedded or post-embedded on the raft foundation, and the sensors are started to collect vibration signals within a certain time period after the completion of the raft foundation; the collected time-domain vibration signals are analyzed and processed, and the maximum displacement value thereof is extracted as the vibration displacement amplitude. The measured amplitude value is compared with the pre-set micro-vibration control target limit value. If the amplitude value does not exceed the limit value, it indicates that the current construction parameters meet the vibration reduction requirements and can be used for subsequent blocks. If the amplitude value exceeds the limit value, it means that the current construction parameters cannot meet the higher vibration reduction standards, and further optimization is required.

[0062] In some embodiments, the raft foundation vibration monitoring and evaluation can be achieved in various ways:

[0063] Optionally, during the pouring of the raft foundation, a certain number of acceleration sensors are uniformly distributed along the surface of the raft foundation to monitor the vibration signals in the vertical and horizontal directions, respectively. After the completion of the raft foundation, vibration data within a certain time period (e.g., 1 hour) is collected under environmental random excitation. The collected data is subjected to digital filtering processing to filter out high-frequency noise and low-frequency drift. Then, the filtered signals are subjected to time-domain integration to obtain the velocity and displacement time history curves. The absolute value peak of the displacement curve is extracted as the amplitude. The amplitude mean value and standard deviation of a plurality of measurement points are calculated as quantitative indicators for evaluating the vibration level. The amplitude statistics are compared with the control target threshold value to give a judgment result of meeting or exceeding the standard.

[0064] Optionally, after the raft foundation is formed, a plurality of measurement points are arranged, and a laser vibration meter is used for active excitation sweep test. The frequency and intensity of the exciter are changed, and the vibration displacement response of each measurement point of the raft foundation is measured. The frequency response curve is drawn to obtain the dynamic amplification characteristics of the raft foundation structure in different frequency bands. The resonance amplification peak near the natural frequency is investigated. If the amplitude corresponding to the peak significantly exceeds the control target, it is considered that the current construction parameters cannot meet the requirements of the structure's anti-resonance ability, and the natural frequency or mode shape amplitude of the raft foundation needs to be further reduced.

[0065] S104, adjusting the current construction parameters to test construction parameters, the test construction parameters being different from the current construction parameters.

[0066] The test construction parameters refer to a new set of construction parameter values obtained by adjusting the original parameters in order to obtain better vibration control effect when the current construction parameters cannot meet the vibration reduction requirements. The rationality and effectiveness of the parameter adjustment are verified by comparing the vibration test results under the new parameters, and the adjustment range of the parameters needs to be determined according to the degree of amplitude exceeding the standard and the experience of engineers.

[0067] Specifically, when the measured amplitude of the pre-block exceeds the target limit, it means that it will be difficult to meet the subsequent higher vibration reduction requirements with the current construction parameters, so it is necessary to optimize and adjust the construction parameters. The construction control system will refer to the excessive amplitude value and output a new set of construction parameters as a test scheme based on the vibration reduction experience of similar projects set by engineers to replace the current construction parameters. Since the vibration characteristics of the structure are sensitive to changes in foundation depth, pile diameter, and pile spacing, the test construction parameters are usually focused on these parameters to increase the overall stiffness of the foundation system by reducing the pile spacing, i.e., increasing the number of piles, thereby reducing the vibration mode amplitude of the superstructure.

[0068] S105, using the current construction parameters as the target construction parameters to construct each block behind the pre-block with the target construction parameters.

[0069] Among them, the target construction parameters refer to a set of standardized construction parameters that can be used in subsequent block construction under the condition that the vibration reduction effect of the pre-block meets the requirements. Using uniform target construction parameters is beneficial to ensure the consistency and reliability of construction quality, and also helps to improve construction efficiency and management level. In fact, the target construction parameters are often gradually evolved from several current construction parameters that confirm the vibration reduction effect, representing the successful experience of previous construction practice and having important value in guiding subsequent construction.

[0070] Specifically, the test results of the pre-block show that when the vibration reduction effect achieved by the current construction parameters meets the micro-vibration control target, this set of parameters is determined as the target construction parameters of the project. Subsequently, in the construction of subsequent structural blocks (numbered 2, 3, 4…), this target parameter will be used as the basis for construction without the need for further testing and adjustment. Since the vibration reduction effect of the target construction parameters has been fully verified on the pre-block, the use of this parameter scheme can ensure that the construction quality of subsequent blocks also meets the expectations without significant changes in structural characteristics.

[0071] S106, constructing the post-block with the test construction parameters, the post-block being the next block after the pre-block.

[0072] Among them, the post-block refers to the next structural block (numbered 2) that is immediately adjacent to the pre-block in the construction sequence. Since it is closest to the pre-block in terms of spatial position and force transmission, it is most suitable for verifying the vibration reduction effect of the test construction parameters. By observing the actual performance of the test construction parameters in the post-block, their advantages and disadvantages relative to the original parameters can be directly compared and evaluated, providing reliable basis for further improving the test construction parameters.

[0073] Specifically, when the original construction parameters are difficult to meet the vibration reduction requirements, the system will output the optimized and adjusted test construction parameters. However, whether the test construction parameters can truly achieve the expected effect still needs to be verified in actual projects. By selecting the next block (numbered 2) of the pre-block (numbered 1) as a pilot, using the test construction parameters to organize construction, and evaluating the vibration reduction effect, the difference in vibration performance before and after the test can be directly compared to demonstrate the rationality of parameter optimization. On the one hand, adjacent blocks are usually similar in geological conditions, structural forms, and other factors, which is conducive to the equivalent comparison of parameter effects. On the other hand, the scale of the pilot block is larger than the pre-block, and even if the test construction parameter effect is not good, the quality problem can be controlled within a local range, avoiding the overall loss.

[0074] S107, taking the combination of the pre-block and the post-block as the pre-block, and taking the test construction parameter as the current construction parameter.

[0075] The combination of the pre-block and the post-block refers to the new overall structure (numbered 1+2) formed by the spatial connection of the two adjacent blocks. Since the two blocks are closely connected in the construction sequence, and the next block has been tested for parameters, the merged structure can maintain continuity in mechanical properties and vibration reduction effect, and can be equivalent to a larger scale pre-block. The test construction parameter has been preliminarily confirmed to have better vibration reduction effect than the original parameter after being verified by the pilot of the post-block.

[0076] Specifically, the post-block and the pre-block are integrated to form a new pre-block (numbered 1+2) with larger scale and higher integrity, which is conducive to simplifying the test evaluation process and enhancing the overall structure vibration resistance. Since the two blocks are closely connected in space and force, and subjected to the same external excitation, the vibration response is consistent, and the vibration reduction effect can be comprehensively evaluated. At the same time, since the post-block uses the test construction parameter, and the vibration reduction effect is better than the original parameter after being verified by the pilot, the test construction parameter can be equivalent to the overall use of the combination block, which can further verify the applicability of the parameter in a larger range, and gradually expand the scale of parameter application. Therefore, after this step S107, the system will return to step S103 to confirm the feasibility of the test construction parameter through further displacement verification.

[0077] The method provided by the embodiment will be further described in more detail. Please refer to Figure 2 , which is another flowchart of the construction control method for the radiation protection structure basic micro-vibration in the embodiment of the present application.

[0078] S201, extracting a target building structure from construction drawings, and dividing the target building structure into N structure blocks connected in sequence.

[0079] Referring to step S101, the construction control system divides the target building structure into N structural blocks.

[0080] In some embodiments, the construction drawings exist corresponding construction parameter reference values for subsequent initial construction parameter determination. The construction parameter reference values are determined by the construction control system obtaining the construction parameters of the historical construction buildings input by the engineers and the corresponding construction quality evaluation indexes; extracting the mapping relationship between the construction parameters and the construction quality evaluation indexes to obtain the recommended value range of each construction parameter; and determining the construction parameter reference values of the recommended value range based on the selection operation of the engineers.

[0081] The construction parameter reference values refer to the preferred value ranges of the construction parameters in the construction experience of the historical similar projects, which are used to guide the selection of the initial construction parameters of the project. The historical construction buildings refer to the completed buildings similar to the project in terms of structural form and geological conditions, and the relevant parameters of the Shanghai Synchrotron Radiation Facility and the Beijing Synchrotron Radiation Facility can be used to guide the construction. The construction quality evaluation index refers to a quantitative index obtained by comprehensively evaluating the construction quality of the completed project, which can reflect the engineering quality level from the aspects of structural safety and use function.

[0082] Specifically, during the project preparation stage, when the design drawings are completed, the construction control system needs to assist the engineers in selecting a suitable set of initial construction parameters to provide a reference basis for subsequent block construction. Since the construction conditions of each project are not the same, the requirements for the parameters are also different, and therefore it is necessary to fully utilize the historical experience data to find the optimal parameter combination under the design conditions of the drawings. The system first collects the construction data of several similar projects from the engineers or the construction database, focusing on the design values of the construction parameters such as pile diameter, pile spacing, and pile length; and extracts the quality evaluation indexes of these projects upon completion of acceptance. Then, the system uses mathematical statistical methods to analyze the internal relationship between the value of each parameter and the comprehensive quality index, and establishes a mapping model of the parameters and the index. Based on the model calculation, a more ideal value interval is divided for each parameter to form a preliminary reference value candidate scheme. Finally, the system submits the candidate range of all parameters to the engineers, who select the preferred values of each parameter based on their own experience and the specific requirements of the project, thereby determining the reference values of the entire set of construction parameters. On this basis, the engineers can further fine-tune the reference values to finally set the initial construction parameters that can be operated.

[0083] It should be noted that the above steps can be implemented by a construction parameter-quality evaluation index mapping model, which establishes a quantitative mapping relationship between the construction parameter value and the engineering quality evaluation index through statistical learning of a large amount of historical engineering data. The specific training process is: collecting construction parameter (such as pile diameter, pile spacing, pile length, etc.) sample data of different projects, extracting corresponding engineering quality comprehensive evaluation index, using multivariate regression analysis and other machine learning algorithms, fitting parameter-index curve, and establishing a mathematical model for quality prediction and parameter optimization. When applied, input the construction parameter trial scheme of the proposed project, and the model estimates the quality qualified probability of the scheme, and then optimizes the parameter selection.

[0084] In some embodiments, the recommended value range of the construction parameter can be obtained and determined in various ways:

[0085] Optionally, the construction control system accesses the enterprise engineering management database to retrieve the built projects with similar design parameters to the project drawings; extracts the construction scheme files of each project to read the construction parameter design values, and extracts the corresponding engineering quality evaluation total score; performs cluster analysis on all value sample points of each construction parameter and their corresponding quality scores to obtain the parameter value interval in which the sample points with higher quality evaluation are concentrated; defines the interval as the recommended value range of the parameter, and repeats the above steps to obtain the recommended range of all parameters; and aggregates the recommended ranges of the parameters to form a candidate scheme for engineers to select.

[0086] Optionally, the construction control system accesses the engineering case library of the industry association, downloads excellent engineering cases similar to the structure form and geological conditions of the project, analyzes the construction drawing design description of each case engineering, reads the construction parameter table therein, extracts the design values of each parameter, accesses the completion acceptance report of the corresponding case, extracts the quality evaluation grade, and performs statistical processing on the excellent case samples of each parameter to remove obvious outliers and obtain a relatively concentrated distribution interval; define the upper and lower limits of the values in the interval as the recommended value range of the parameter, and finally obtain the recommended range of the selected scheme of all parameters; the system generates a scheme report for engineers to review, and determines the optimal value of each parameter.

[0087] S202, obtain initial construction parameters, take the first structure block as the front block, take the initial construction parameters as the current construction parameters, and take the current construction parameters to construct the front block.

[0088] Referring to step S102, the construction control system will construct the first structure block (front block).

[0089] S203, test the vibration displacement amplitude of the raft of the front block, and determine whether the vibration displacement amplitude is not higher than the micro-vibration control target.

[0090] Referring to step S103, the construction control system determines whether the vibration displacement of the preceding block meets the requirements.

[0091] S204, determining a current vibration frequency corresponding to the current construction parameter according to the displacement frequency spectrum of the preceding block.

[0092] The displacement frequency spectrum is a frequency-amplitude curve obtained by Fourier transform of the block vibration displacement, used to represent the vibration characteristics of the block. The current vibration frequency refers to the dominant vibration frequency generated by the block when the preceding block is constructed using the current construction parameter.

[0093] Specifically, after the construction of the preceding block is completed, the construction control system tests the vibration displacement data of the block using sensors, and performs Fourier transform on the data to obtain the displacement frequency spectrum of the block. By finding the frequency component with the largest amplitude in the spectrum, the current vibration frequency generated by the block using the current construction parameter can be determined. This frequency reflects the vibration characteristics of the preceding block under the current construction parameter.

[0094] In some embodiments, the determination process can be achieved by the following steps: after the construction of the preceding block is completed, a plurality of vibration sensors are arranged on the raft of the block; the vibration displacement data of each measurement point of the raft within a certain time period is collected using the vibration sensors; Fourier transform is performed on the data of each measurement point to obtain the displacement amplitude-frequency curve of each point; the amplitude-frequency curves of all measurement points are superimposed and averaged to obtain the displacement frequency spectrum of the entire preceding block; the frequency corresponding to the maximum peak value of the spectrum is found, which is determined as the current vibration frequency.

[0095] S205, using the current construction parameter as the target construction parameter, and constructing each block behind the preceding block using the target construction parameter.

[0096] Referring to step S105, after the construction control system determines the target construction parameter, it will construct each block behind the preceding block using the target construction parameter.

[0097] S206, adding a preset frequency value to the current vibration frequency to obtain an expected vibration frequency.

[0098] The preset frequency value is a frequency value set in advance based on experience or theoretical analysis. By increasing this value based on the current vibration frequency, the vibration frequency of the block can be increased to the expected vibration frequency. The expected vibration frequency is a target frequency that the vibration frequency of the block is expected to reach in subsequent construction by adjusting the construction parameter, which is usually higher than the current vibration frequency.

[0099] Specifically, when the current vibration displacement amplitude exceeds the micro-vibration control target as tested in step S203, it means that the vibration frequency of the block as a whole needs to be further increased to reduce the amplitude. To increase the frequency to the desired level, a desired vibration frequency can be set as the target for adjustment. The value can be obtained by superimposing a preset frequency value on the current vibration frequency. The preset frequency value can be calculated and determined in advance according to the degree of current vibration level exceeding the standard, site conditions and other factors.

[0100] In some embodiments, the determination of the preset frequency value requires the construction control system to collect the power spectrum of the site where the target building is located; then determine the predominant frequency of the ground pulsation according to the power spectrum; and finally determine the preset frequency value based on the predominant frequency and the current vibration frequency.

[0101] The site where the target building is located refers to the area where the proposed engineering project is located, and detailed geological survey of the natural environmental conditions such as geological structure and soil distribution is usually required. The power spectrum is a curve representing the frequency characteristics of a random signal, obtained by Fourier transform of the autocorrelation function of the signal, reflecting the energy distribution of the signal at each frequency component, and is commonly used to analyze the frequency domain characteristics of random excitations such as earthquakes and wind loads. The ground pulsation refers to the weak vibration of the earth's crust in a non-seismic state, mainly caused by natural factors such as wind, flowing water, temperature difference, etc. The predominant frequency refers to the frequency peak value that stands out significantly in the frequency spectrum of the signal, which usually has an important influence on the vibration response of the system.

[0102] Specifically, when the actual measurement shows that the current construction scheme is difficult to meet the vibration control requirements, it is necessary to further optimize the structural parameters to improve its anti-vibration performance. The core of vibration control is to avoid the resonance region of the structure and the environmental excitation, so that the natural frequency of the structure is far away from the external disturbance frequency. In order to find out the appropriate target frequency, first of all, the dynamic characteristics of the environment in which the structure is located should be fully understood. The system arranges a site vibration detection array to collect the ground microseismic data of the site soil within a certain period of time; using signal processing algorithms such as fast Fourier transform, the ground microseismic data is analyzed to obtain the power spectral density curve of the site vibration; the frequency point with the maximum peak value and the most prominent is identified from the power spectrum curve, which is determined as the predominant frequency of the site microseismic, which is usually the component that needs to be focused on avoiding in the vibration control of the structure. After the predominant frequency of the site is determined, it is compared with the measured vibration frequency of the structure under the current construction parameters. If they are close, there is a risk of resonance, and the construction parameters need to be adjusted in time to increase the structural frequency and widen the gap with the predominant frequency. According to experience, a preset frequency adjustment value such as 5Hz or 10Hz can be set, which is directly added to the existing vibration frequency as the new target frequency, i.e. the expected frequency, and then the corresponding construction parameter adjustment scheme is matched. In some embodiments, the preset frequency adjustment value can also be represented by the corresponding equivalent frequency, i.e. how many times the original frequency is increased, such as changing the expected vibration frequency to 1.02 times the current vibration frequency.

[0103] S207, bind the expected vibration frequency to the corresponding test construction parameter.

[0104] Among them, the binding of the expected vibration frequency to the test construction parameter means establishing the corresponding relationship between the two, so that the frequency becomes the vibration frequency target reached when the test construction parameter is used.

[0105] Specifically, after determining the expected vibration frequency, a new set of parameters different from the current construction parameters needs to be selected as the test construction parameter for the trial construction of the post-block. In order to make the vibration frequency of the test construction as close as possible to the expected vibration frequency, the expected vibration frequency can be used as the frequency target of the construction control and bound to the test construction parameter. After binding, once the test construction parameter is determined, the corresponding expected vibration frequency is also determined.

[0106] S208, determine the expected vibration frequency bound to the test construction parameter, and obtain the pre-equivalent mass of the pre-block.

[0107] Among them, the expected vibration frequency refers to a target frequency reached by adjusting the construction parameters in subsequent construction. The pre-equivalent mass refers to a mass value that can equivalently represent the overall equivalent mass characteristics of the pre-block.

[0108] Specifically, when a certain set of test construction parameters is determined, the parameters must correspond to an expected vibration frequency. To analyze the construction requirements of the post-block at the expected vibration frequency, the mass characteristic parameters of the pre-block, i.e., its equivalent mass, need to be obtained.

[0109] In some embodiments, the binding of the expected vibration frequency and the test construction parameters and the acquisition of the pre-equivalent mass can be achieved in various ways:

[0110] Alternatively, the system retrieves one or more sets of construction parameters corresponding to the expected vibration frequency calculated in step S206 from the construction parameter database as alternatives; then the engineer selects one set from the alternative construction parameters as the final test construction parameters, and stores the mapping relationship between it and the expected vibration frequency. At the same time, the system extracts key material parameters such as the amount of concrete and the amount of steel reinforcement from the design drawings of the pre-block; combined with the density parameters of each material, the equivalent mass estimate of the pre-block is calculated through the volume-mass conversion formula.

[0111] S209, determine the expected frequency range corresponding to the expected vibration frequency.

[0112] Among them, the expected frequency range refers to a frequency interval formed by floating a certain percentage up and down around the expected vibration frequency. Due to the uncertainty of actual construction, it is difficult to accurately control to a certain frequency value, so an acceptable frequency range is set with the expected vibration frequency as the target, and as long as the measured frequency falls within the range, it is considered to meet the control requirements.

[0113] Specifically, after the expected vibration frequency corresponding to the test construction parameters is determined, the frequency deviation that may exist in actual construction also needs to be considered. By floating a certain percentage, such as ±5%, up and down around the expected vibration frequency, an expected frequency control interval is determined. The frequency values within this interval are considered acceptable and qualified frequency control results.

[0114] In some embodiments, the expected frequency range can be determined in various ways:

[0115] Alternatively, the system reads the expected vibration frequency value based on the frequency floating percentage parameter set by the engineer, and floats the upper and lower limits of the frequency interval by the percentage to form the expected frequency range; when the frequency floating percentage is default, the system automatically calls the experience value, such as ±5%, to generate the default expected frequency range.

[0116] Optionally, the system accesses the construction frequency control data of the same type of project, statistically analyzes the actual construction frequency value, extracts the mean and standard deviation of the frequency value sample, and forms an expected frequency range based on the mean value and the percentage corresponding to the upper and lower floating of two standard deviations. If the statistical sample data is insufficient, a limited sample estimation interval method is used to obtain a higher confidence expected frequency range.

[0117] It can be understood that the determination of the expected frequency range can also use other statistical or engineering experience methods to determine a reasonable range width as much as possible under the premise of ensuring the control effect, and provide a certain frequency margin for actual construction, which is not limited in detail here.

[0118] S210, the number of raft piles of the post-positioned block construction is obtained, so that the overall equivalent mass and the overall equivalent stiffness satisfy the calculation result of the pre-design calculation formula within the expected frequency range.

[0119] The number of raft piles refers to the total number of pile foundations that need to be laid in the raft foundation construction. The number of piles directly affects the quality and stiffness characteristics of the entire foundation structure. The overall equivalent mass is the sum of the pre-positioned equivalent mass of the pre-positioned block and the post-positioned equivalent mass of the post-positioned block, representing the mass characteristics of the entire structure after the two blocks are connected. The overall equivalent stiffness is a value that can be equivalent to represent the stiffness characteristics of the entire structure after the two blocks are connected. The pre-design calculation formula is a frequency calculation formula derived from the theory of structural dynamics, and the mass and stiffness of the structure are two variables.

[0120] Specifically, after adding the post-positioned block on the pre-positioned block, the equivalent mass and equivalent stiffness of the entire structure will change. In order to control the construction frequency of the post-positioned block within the expected frequency range, it is necessary to adjust the number of foundation piles of the post-positioned block to adjust its equivalent mass and stiffness. Since the increase or decrease of the number of piles will cause the simultaneous change of the mass and stiffness, the overall equivalent mass and overall equivalent stiffness of the two blocks can be substituted into the pre-set frequency calculation formula, and through repeated iteration, the pile arrangement scheme that can make the calculation frequency fall within the expected frequency range is found out, thereby guiding the foundation construction of the post-positioned block.

[0121] In some embodiments, the relationship between the vibration frequency f and the mass m and the stiffness k can be represented by the formula: for each vibration frequency, there is a corresponding relationship between the stiffness and the mass, that is, And for the stiffness k and the mass m, they are often determined by the number of raft piles n, and the stiffness k and the mass m often have a complex nonlinear relationship with the number of raft piles n, which cannot be simply calculated.

[0122] For the current vibration frequency of the pre-positioned block wherein f1 does not meet the preset frequency requirement; and the expected vibration frequency is set as f1+0.2f1, i.e. 1.2 times of f1, and assuming that the range interval fluctuation is 0.02f1, the expected frequency range is set as 1.18f1-1.22f1. At this time, corresponding to the raft pile number n of the post-positioned block, if the calculated overall equivalent mass m i and the overall equivalent stiffness k i satisfy wherein f i needs to be within the interval of 1.18f1-1.22f1.

[0123] The overall equivalent mass m i depends on the sum of the pre-positioned equivalent mass m1 and the post-positioned equivalent mass m2, and the mass can be obtained by calculating the proportion of the concrete and the pile number, i.e. the post-positioned equivalent mass m2 can be determined by the raft pile number n. The overall equivalent stiffness k i also depends on the design of the raft pile number n. That is, the overall frequency f i depends on the raft pile number n, and a reasonable n is set to ensure that the frequency f i is within the interval of 1.18f1-1.22f1, i.e. the construction requirement can be met.

[0124] In some embodiments, the construction control system can determine a corresponding pile number estimation range according to the expected frequency range, calculate the overall equivalent mass and the overall equivalent stiffness corresponding to the raft pile number based on the raft pile number in the pile number estimation range selected by the engineer, determine whether the calculation result of substituting the overall equivalent mass and the overall equivalent stiffness into the pre-designed calculation formula is within the expected frequency range, and if not, prompt the engineer to reselect the raft pile number.

[0125] wherein the pile number estimation range is a pile number variation interval inversely estimated by the pre-designed calculation formula according to the expected frequency range, and provides a reference for the selection of the raft pile number. If the actually selected raft pile number fails to meet the expected frequency range after calculation, the pile number needs to be adjusted for recalculation.

[0126] Specifically, once the expected frequency range required for the construction of the subsequent blocks is determined, a rough estimate of the number of piles corresponding to this frequency range can be made using a preset frequency calculation formula. This serves as a preliminary basis for pile selection. Then, within this estimated range, the engineer selects a specific number of raft foundation piles. Based on this number of piles and the known parameters of the preceding blocks, the system calculates the equivalent mass and equivalent stiffness of the two blocks under this pile arrangement using empirical formulas or finite element analysis. The calculated overall mass and stiffness are then substituted into the preset frequency calculation formula to verify the specific frequency value within the expected frequency range under these parameters. If the calculation results indicate that the actual frequency exceeds the expected frequency range, the system indicates that the pile selection is unreasonable and needs adjustment. The engineer must then reselect a number of piles within the estimated pile range and perform the calculation again until the frequency requirements are met.

[0127] In some embodiments, the number of raft sheet piles can be calculated and selected in a variety of ways:

[0128] Optionally, the system calculates the maximum and minimum number of piles that can be arranged per unit area of ​​raft foundation based on parameters such as the thickness of the raft foundation concrete and the pile spacing marked in the engineering design drawings, combined with the single pile bearing capacity required by the specifications. Within this range, it divides the number of piles into several candidate values. Then, it checks the overall frequency under each candidate number of piles one by one, selects the number of piles that meets the expected frequency range as the proposed value, and submits it to the engineer for approval.

[0129] It is understandable that the calculation and selection of the number of raft sheet piles can be combined with specific engineering conditions. Under the premise of ensuring the safety of the foundation bearing capacity, various calculation and verification methods can be flexibly adopted, as long as the expected frequency control requirements can be met. No restrictions are imposed here.

[0130] S211, the post-construction block based on the equivalent mass and number of raft piles.

[0131] Among them, the post-equivalent mass refers to a mass value that can equivalently represent the overall equivalent mass characteristics of the post-block, which can be calculated based on the number of raft piles determined in step S210.

[0132] Specifically, after calculation and verification in step S210, the pile layout scheme for the raft foundation of the subsequent block was finally determined, and the corresponding equivalent mass value was also obtained. During the formal construction of the subsequent block, the amount of materials such as concrete and steel reinforcement needs to be strictly controlled to ensure that the actual structural mass matches the calculated equivalent mass value. Simultaneously, during pile foundation construction, the piles must be laid out strictly according to the determined pile positions, diameters, and lengths to ensure that the number of piles matches the design and that the pile quality meets the requirements. Only when the mass and stiffness parameters of the subsequent block meet the design requirements can its vibration frequency be controlled within the expected range and matched with the vibration performance of the preceding block.

[0133] In some embodiments, the construction control of the post-positioned block can be achieved in various ways:

[0134] Optionally, the construction control system converts the post-positioned equivalent mass design value into the mass usage control index of each construction material, such as the total amount of steel reinforcement, the amount of concrete, etc., as the basis for material acceptance and construction proportioning; the system collects the material usage data of the construction site in real time, compares the design usage, and timely warns and corrects, to ensure that the actual mass of the structure is controlled. At the same time, the system converts the raft pile number scheme into a specific pile coordinate and a pile length and diameter parameter table, and transmits it to the pile machine control system; the pile machine is positioned by measuring equipment such as a total station and GPS, and the drilling depth and hole diameter are controlled, to realize accurate control of pile foundation construction.

[0135] It can be understood that there are many means for construction control of the post-positioned block, and the key is to establish an accurate correspondence between the design parameters and the construction process, to achieve controlled construction in the whole process and all factors, and to ensure that the key characteristics such as the quality and stiffness of the post-positioned block meet the needs of vibration control and are coordinated with the vibration performance of the pre-positioned block.

[0136] S212, taking the combination of the pre-positioned block and the post-positioned block as the pre-positioned block, and taking the test construction parameter as the current construction parameter.

[0137] Referring to step S107, after the system executes step S211, it will be called back to step S204 to confirm the feasibility of the test construction parameter through further displacement verification.

[0138] In the embodiments of the present application, the complex large-scale building structure is divided into a plurality of independently controllable sub-blocks, and then a "test-evaluation-optimization" iterative construction control strategy is adopted for each sub-block, effectively solving the problem that large-scale complex structures are difficult to achieve precise vibration control. In each sub-block, the vibration reduction effect of the current construction parameter is quickly judged by measuring the structure vibration response, and the test parameter is automatically optimized to continuously improve, which can significantly improve the fine control level. Then, through small-batch trial and error and incremental optimization, the vibration control effect is maximized within the controllable risk, and finally the high-precision micro-vibration control of the large-scale building is realized under the constraints of time and cost.
