Description

Technical Field

[0001] This application relates to the fields of low-carbon technology and construction technology, and in particular to a method and apparatus for obtaining target repair schemes based on prefabricated underground continuous walls. Background Technology

[0002] As a key load-bearing and enclosure component of prefabricated underground structures, precast diaphragm walls play a crucial role in the overall structural system, bearing important functions such as resisting earth pressure, water pressure, and transmitting superstructure loads. Damage to precast diaphragm walls directly weakens the load-bearing capacity of the prefabricated underground structure. To prevent further damage to precast diaphragm walls and the resulting adverse consequences, it is necessary to obtain a targeted repair solution for them.

[0003] However, the current process for obtaining target repair solutions for precast diaphragm walls is cumbersome, hindering the improvement of efficiency. This is because existing technologies primarily rely on manual methods to acquire these solutions, which consumes significant human and time resources, increasing the acquisition time and making them susceptible to human intervention. Therefore, this approach is detrimental to improving the efficiency of obtaining target repair solutions for precast diaphragm walls. Summary of the Invention

This application embodiment does not impose any restrictions on the specific type of electronic device.

[0032] Please see Figure 1 , Figure 1 The application scenario diagram of the target repair scheme acquisition method based on prefabricated diaphragm walls provided in the embodiments of this application is described in detail below: The electronic equipment acquires monitoring data of the precast diaphragm wall from the monitoring system, and obtains the strain value of the precast diaphragm wall at the current moment from the monitoring data.

[0033] In this embodiment of the application, obtaining the strain value of the precast underground continuous wall at the current moment can help detect potential safety hazards in advance.

[0034] Please see Figure 2 , Figure 2 This is a flowchart illustrating a method for obtaining a target repair scheme based on a prefabricated diaphragm wall, provided in an embodiment of this application. This method can be applied to electronic devices.

[0035] like Figure 2 As shown in the figure, the method for obtaining a target repair scheme based on a prefabricated diaphragm wall provided in this application includes the following steps, which are detailed below: S201, Obtain monitoring data of the precast diaphragm wall from the monitoring system, and obtain the strain value of the precast diaphragm wall at the current moment from the monitoring data; Among them, precast underground continuous wall is a continuous underground wall structure formed by using reinforced concrete or prestressed concrete wall panels produced by factory prefabrication process, which are transported to the construction site and hoisted into a pre-excavated deep trench, and then solidified and spliced ​​using cement grout or self-hardening materials.

[0036] Precast diaphragm walls can be used in underground stations. For ease of explanation, an example is given below: Precast diaphragm walls serve as temporary support structures for foundation pits during the construction phase. They are quickly assembled from standardized precast components to form a retaining and water-stopping barrier, ensuring excavation safety. Once the main structure is completed, only a waterproof coating and decorative surface treatment are needed on the outside of the wall to directly transform it into the enclosure structure of a subway station.

[0037] This includes acquiring monitoring data of the precast diaphragm wall from the monitoring system, and obtaining the strain value of the precast diaphragm wall at the current moment from the monitoring data, including: Access the data log file of the monitoring system, obtain the monitoring data of the precast diaphragm wall from the data log file, and obtain the strain value of the precast diaphragm wall at the current moment from the monitoring data.

[0038] S202. Based on the strain value, negative strain extreme value and strain model of the precast diaphragm wall at the current moment, the strain function of the precast diaphragm wall is obtained. The negative strain extreme value is the maximum deformation value of the precast diaphragm wall under compression within the detection range. The strain model is as follows: ; It is the strain value of the precast diaphragm wall at the current moment; It is the negative strain extreme value, which is the maximum deformation value of the precast underground continuous wall under compression within the detection range; It is the current moment; It is the strain function of the precast diaphragm wall.

[0039] S203, when the strain value is greater than the set strain threshold, the cavity ratio of the precast diaphragm wall is generated based on the volume of the solid of the precast diaphragm wall, the volume of the cavity of the precast diaphragm wall, and the cavity model. The recovery factor of the precast diaphragm wall is generated based on the cavity ratio and factor model of the precast diaphragm wall. The performance function of the precast diaphragm wall is obtained based on the recovery factor, the strain function and performance model of the precast diaphragm wall. The cavity model is as follows: ; It is the volume of the precast diaphragm wall. It is the cavity ratio of the precast diaphragm wall; It is the volume of the cavity in the precast diaphragm wall.

[0040] Please see Figure 3 , Figure 3 Example diagrams of prefabricated diaphragm walls provided for embodiments of this application are detailed below: Figure 3 The solid structure of the precast diaphragm wall and the cavity of the precast diaphragm wall are shown.

[0041] Precast diaphragm walls consist of both solid and hollow components. The solid portion is the core load-bearing component of the precast diaphragm wall, typically constructed from high-strength concrete and internally reinforced with steel bars. With its high strength and rigidity, it bears the heavy responsibility of resisting pressure from the surrounding soil, water pressure, and various loads transmitted from the superstructure, providing reliable support and enclosure for the precast underground structure and ensuring its stability and safety in complex environments.

[0042] The cavity is the internal space reserved during the design and manufacturing process of the precast underground continuous wall. The cavity can be flexibly utilized according to actual engineering needs, such as for laying various pipelines to meet the functional requirements of underground facilities such as power supply, communication, water supply and drainage.

[0043] The factor model is as follows: ; It is the recovery factor of the precast diaphragm wall; the larger the recovery factor of the precast diaphragm wall, the stronger its self-recovery ability; the smaller the recovery factor of the precast diaphragm wall, the weaker its self-recovery ability. It is the cavity ratio of the precast diaphragm wall; These are preset correction coefficients, which are obtained through regression analysis of full-scale experimental and finite element simulation data.

[0044] S204. Through the carbon emission model, the carbon cost coefficient corresponding to each initial repair scheme is obtained. Based on the performance function of the precast diaphragm wall, the carbon cost coefficient corresponding to each initial repair scheme, the start time of repair of the precast diaphragm wall and the toughness model, the toughness repair score of the precast diaphragm wall using each initial repair scheme is generated. The performance model is as follows: ; It is a performance function of precast diaphragm walls; It is the time required for a precast diaphragm wall to fully recover to its initial state after yielding strain. It is an adjustment factor; It is a restoring factor for precast diaphragm walls; It is a performance correction factor.

[0045] in, ; It is a correction factor; These are the state values ​​of the precast diaphragm wall during its application stage; This indicates that the application stage of precast diaphragm walls is the retaining wall stage. This indicates that the application stage of precast underground continuous walls is the operational wall stage.

[0046] The retaining wall stage is a temporary support stage during the construction period, providing a safe and stable working environment for the excavation of the foundation pit and the construction of the underground structure. During the temporary support stage, the precast underground continuous wall only needs to meet the short-term temporary load-bearing and seepage prevention requirements, without having to take into account the long-term performance.

[0047] The operational wall phase is a permanent phase in the project cycle. During this phase, the precast diaphragm wall needs to bear loads, provide waterproofing, and divide space for an extended period. Therefore, it must meet stringent requirements for long-term load-bearing stability, durability, and permanent waterproofing to ensure the long-term safe operation of the building.

[0048] S205, sort the toughness repair scores obtained by each initial repair scheme for the precast diaphragm wall, and select the initial repair scheme with the highest toughness repair score as the target repair scheme for the precast diaphragm wall.

[0049] Among them, the worse the toughness repair score obtained by the initial repair scheme for the precast diaphragm wall, the weaker the performance of the initial repair scheme in terms of both toughness repair and carbon emissions. Conversely, the higher the toughness repair score obtained by the initial repair scheme, the stronger the performance of the initial repair scheme in terms of both toughness repair and carbon emissions. Therefore, the initial repair scheme with the highest toughness repair score was selected as the target repair scheme for the precast diaphragm wall. The target remediation plan achieves a balance between safety and low carbon emissions by reducing carbon emissions and resource consumption and lowering environmental governance costs.

[0050] Among them, the toughness repair scores obtained by each initial repair scheme for the precast diaphragm wall are ranked, and the initial repair scheme with the highest toughness repair score is selected as the target repair scheme for the precast diaphragm wall, including: Obtain the sorting function from the configuration file, and sort the toughness repair scores of the precast diaphragm wall obtained by each initial repair scheme using the sorting function to obtain the sorting results; The initial repair scheme with the highest toughness repair score was selected from the ranking results as the target repair scheme for the precast diaphragm wall.

[0051] The carbon emission model is shown below: ; in, It is the first The carbon cost coefficient corresponding to each initial remediation plan; For the first In the initial repair plan, the first step in the manufacturing process... The consumption of various repair materials For the first In the first initial repair plan, the first Carbon emission factors of the remediation materials This represents the total number of material types. For the first The initial repair plan was implemented during the transportation phase. The amount of transportation work completed by a certain type of transportation vehicle. For the first Carbon emission factors of various transportation vehicles This represents the total number of transport vehicle types, where a transport vehicle is a means of transporting repair materials or construction equipment. For the first The initial repair plan was implemented during the construction phase. The consumption of this type of energy, For the first Carbon emission factors of various energy sources The total number of energy types; For the first The initial repair plan was the first in the cleanup phase. The amount of waste generated, For the first Carbon emissions from waste during the treatment process This represents the total number of waste types.

[0052] In one possible implementation of the first aspect, the resilience model is as follows: ; The precast diaphragm wall adopts the first The toughness repair score of each initial repair scheme; The larger the value, the more likely the precast diaphragm wall adopts the [specific type / method]. The stronger the initial repair solution is in terms of both resilience and carbon emissions; The smaller the value, the more likely the precast diaphragm wall adopts the first... The worse the initial repair solution performs in terms of both resilience repair and carbon emissions; It is the current moment; It is a performance function of precast diaphragm walls, used to describe the change of the real-time performance value of precast diaphragm walls with the current moment; This is the moment when the precast diaphragm wall begins repair; It refers to the repair time of precast diaphragm walls; It is the first The carbon cost coefficient corresponding to each initial remediation plan; The larger the value, the smaller the toughness repair score of the precast diaphragm wall; The smaller the value, the greater the toughness repair score of the precast diaphragm wall; It refers to the original performance value of the precast diaphragm wall, which is the performance value of the precast diaphragm wall under intact conditions. It refers to the repair time; It is the cumulative amount of the performance function of the precast diaphragm wall during the repair time; and The product of represents the cumulative amount of the original performance value of the precast diaphragm wall over the repair period.

[0053] The method for obtaining the target repair solution in this application can be applied to the monitoring system of underground stations. For ease of explanation, an example is given below: The monitoring system of the underground station adopts the target repair scheme acquisition method of this application to acquire monitoring data. The monitoring data shows that the strain value of the precast diaphragm wall rises sharply at the current moment. When the strain value exceeds the set strain threshold, the monitoring system acquires multiple different initial repair schemes from the strategy library. Through the carbon emission model, the carbon cost coefficient corresponding to each initial repair scheme is obtained. Based on the performance function of the precast diaphragm wall, the carbon cost coefficient corresponding to each initial repair scheme, the start repair time of the precast diaphragm wall, and the toughness model, a toughness repair score is generated for the precast diaphragm wall using each initial repair scheme. The toughness repair scores of the precast diaphragm wall using each initial repair scheme are sorted, and the initial repair scheme with the highest toughness repair score is selected as the target repair scheme for the precast diaphragm wall.

[0054] The construction team viewed a report containing precise damage location and target repair plan through the monitoring system's human-machine interface. Based on this report, the construction team responded quickly and completed the repair of the precast diaphragm wall within the specified time.

[0055] in, To evaluate the resilience of a single precast diaphragm wall, a prefabricated underground structure composed of multiple precast diaphragm wall segments contains hundreds or even thousands of sensors, generating massive amounts of real-time monitoring data. Performing detailed resilience calculations for every single data point throughout the entire process would incur a huge computational burden, and a large amount of irrelevant data would obscure truly critical risk information, leading to inefficient assessments and delayed early warnings. To address this challenge, a resilience assessment function for prefabricated underground structures is proposed.

[0056] Following S205, the target remediation plan also includes: Based on the toughness evaluation function of prefabricated underground structures, a set of toughness values ​​for prefabricated underground structures are generated.

[0057] The toughness evaluation function for prefabricated underground structures is: ; in, These are a set of toughness values ​​for prefabricated underground structures; It is the smallest function; It is the maximum function; It is the number of samples whose values ​​are less than the median; It is the maximum toughness repair score of the first precast underground continuous wall; It is the maximum toughness repair score of the second precast underground continuous wall; It is the first The maximum toughness repair score of a precast underground continuous wall segment.

[0058] Specifically, the toughness repair scores of each initial repair scheme for the first precast diaphragm wall were sorted, and the maximum toughness repair score of the first precast diaphragm wall for each initial repair scheme was selected as the maximum toughness repair score of the first precast diaphragm wall.

[0059] Among them, the toughness repair scores of each initial repair scheme for the second precast diaphragm wall were sorted, and the maximum toughness repair score of the second precast diaphragm wall for each initial repair scheme was selected as the maximum toughness repair score of the second precast diaphragm wall.

[0060] Among them, for the first The precast diaphragm wall sections were ranked based on the toughness repair score of each initial repair scheme, and the first-ranked section was selected. For precast diaphragm walls, the maximum toughness repair score among each initial repair scheme is used as the first repair score. The maximum toughness repair score of a precast underground continuous wall segment.

[0061] Specifically, the toughness repair score of each precast diaphragm wall segment using each initial repair scheme is obtained, and the maximum value among the toughness repair scores of each precast diaphragm wall segment using each initial repair scheme is selected as the maximum toughness repair score of each precast diaphragm wall segment. Based on the maximum toughness repair score of each precast diaphragm wall segment and the toughness evaluation function of the precast underground structure, a set of toughness values ​​of the precast underground structure is generated.

[0062] Among them, the toughness assessment function for prefabricated underground structures will After performing exponential calculations, a set of toughness values ​​for the prefabricated underground structure will be obtained.

[0063] For ease of explanation, the following example is provided: for example, The values ​​are: 0.7, 0.8, 0.9; Samples with a value less than 0.95 were selected: 0.7, 0.8, and 0.9.

[0064] Calculate the median of these samples: after arranging the data from smallest to largest, the middle number is 0.8.

[0065] The number of samples with a statistical value less than 0.8 is only 0.7. Therefore, at this time... It is 1.

[0066] It is in array form, at this time, =[0.75,0.83,0.92] The maximum value of 0.92 indicates that the prefabricated underground structure has strong resistance to damage, collapse, and post-earthquake recovery, effectively preventing overall structural failure. The minimum value of 0.75 identifies the first prefabricated diaphragm wall as a weak component. The advanced nature and low-carbon characteristics of the toughness assessment function for prefabricated underground structures are reflected in the following three aspects: 1. The toughness assessment function for prefabricated underground structures does not simply average all monitoring data. Instead, it intelligently focuses on critical areas where performance degradation and low toughness values ​​occur first. Through algorithms, it automatically filters out a large amount of monitoring data that is in an elastic, undamaged state, significantly reducing data processing volume and computational energy consumption. This achieves energy conservation and enables the system to perform real-time assessments on ordinary servers, meeting the practical needs of engineering sites.

[0067] 2. The toughness assessment function for prefabricated underground structures possesses an intelligent risk amplification effect, accurately identifying weak points in the structural system. When only a single area experiences a slight decrease in toughness, the overall toughness degradation is not significant, and the system determines that the problem can be resolved through precise local repairs, avoiding excessive intervention. When the toughness of a single area decreases severely, the overall toughness will rapidly degrade, issuing a strong warning that the damage at that location may trigger continuous failure, requiring immediate targeted reinforcement measures. When multiple areas experience simultaneous toughness degradation, the overall toughness will be significantly lower than the minimum value among all values. This uneven decline accurately reflects the overall risk faced by the structural system due to multiple damage points, necessitating the initiation of a systematic reinforcement plan.

[0068] 3. The toughness assessment function of prefabricated underground structures can identify weak components as key maintenance targets, thereby minimizing the huge material waste, energy consumption and construction waste caused by preventive over-strengthening, and achieving carbon emission reduction from the source.

[0069] The beneficial effects of this application's embodiments are twofold. Firstly, by using a carbon emission model, the carbon cost coefficient corresponding to each initial repair scheme is obtained. Based on the performance function of the precast diaphragm wall, the carbon cost coefficient corresponding to each initial repair scheme, the start time of the precast diaphragm wall's repair, and the toughness model, a toughness repair score is generated for the precast diaphragm wall using each initial repair scheme. The toughness repair scores are then sorted, and the initial repair scheme with the highest toughness repair score is selected as the target repair scheme for the precast diaphragm wall. Since there is no need for manual acquisition of the target repair scheme for the precast diaphragm wall, the acquisition time is reduced, which is beneficial to the efficiency of acquiring the target repair scheme for the precast diaphragm wall. Secondly, the higher the toughness repair score obtained by the precast diaphragm wall using the initial repair scheme, the stronger the performance of the precast diaphragm wall using the initial repair scheme in terms of both toughness repair and carbon emissions. Therefore, selecting the initial repair scheme with the highest toughness repair score as the target repair scheme for the precast diaphragm wall allows the target repair scheme to simultaneously take into account safety and low carbon emissions.

The third acquisition module 404 is used to obtain the carbon cost coefficient corresponding to each initial repair scheme through the carbon emission model, and generate the toughness repair score of the precast diaphragm wall using each initial repair scheme based on the performance function of the precast diaphragm wall, the carbon cost coefficient corresponding to each initial repair scheme, the start repair time of the precast diaphragm wall and the toughness model. The fourth acquisition module 405 is used to sort the toughness repair scores obtained by each initial repair scheme for the precast diaphragm wall, and select the initial repair scheme with the highest toughness repair score as the target repair scheme for the precast diaphragm wall.
