Description

Technical Field

[0001] The invention relates to the technical field of physical analysis, and in particular to a soil penetration and damage test system and method for a foundation pit support and waterproofing system. Background Art

[0002] In the field of foundation pit support waterproofing system, foundation pit support, as an important part of underground engineering construction, involves complex soil environment and changeable water conditions, and the handling of soil penetration problems is crucial. Soil penetration damage test can accurately evaluate the reliability of waterproofing system and the stability of soil structure by simulating different penetration scenarios, which helps to discover potential risk points in advance and optimize and improve them, improve the effect of waterproofing projects, reduce the damage of leakage and water damage to underground buildings, and thus improve the stability and safety of foundation pit support structure in practical applications.

[0003] Prior art, such as a tailings pond seepage damage simulation test device and its test method, is disclosed in the invention patent announcement with announcement number: CN115979923B. The test box of the test device is sealed and fixed on the upper end of the test platform. The water level regulating box and the return water tank of the test box are adjacent to the wall plate of the tailings construction box and are provided with a plurality of water holes and are equipped with water stop plugs. The tailings pond accumulation model is proportionally constructed in the tailings construction box according to the principle of geometric similarity of the actual accumulation dam. The adjustable rainfall system is arranged on the inner wall of the tailings construction box. The soluble channel assembly and the sensor assembly are buried in the tailings pond accumulation model in layers and intervals. The camera is arranged above the tailings construction box. The receiver assembly of the data acquisition system is electrically connected to the sensor assembly and the camera respectively. The test method includes preparation of the tailings pond accumulation model, self-inspection of each component, saturation of the tailings pond accumulation model, preparation of the soluble channel, simulated rainfall, and data acquisition.

[0004] Prior art, such as a soil penetration damage test system and method for a foundation pit support and water-stopping system disclosed in a patent application with publication number: CN119023527A. The test system includes: a test soil sample simulation device, a water supply device, a data monitoring device, and an image acquisition device. The test soil sample simulation device can be divided into a water inlet area, a soil sample area, a support and water-stopping system leakage simulation component, and a drainage area. The water supply device includes a lifting assembly and a water supply assembly. The lifting assembly is suitable for driving the water supply assembly to lift and lower. The water supply assembly is connected to the water inlet area through a water supply hose to provide a constant water head height for the test soil sample. The data monitoring device is used to record the pore water pressure of the test soil sample and the outlet flow of the drainage area. The image acquisition device includes a high-pixel camera and a camera tripod, which are used to record the image data of the test soil sample in real time.

[0005] Combined with the above scheme, it is found that currently in the field of soil permeability and damage test technology, usually only the leakage of foundation pit support and waterproofing system is analyzed. However, the leakage test of foundation pit support and waterproofing system will be affected by various factors such as soil structure, which makes the soil permeability characteristics and leakage process have great uncertainty. It is impossible to effectively control the external variables in the test environment, which may lead to poor repeatability of test results and affect the reliability and accuracy of test data. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a soil penetration and damage test system and method for a foundation pit support and waterproofing system, which can effectively solve the problems involved in the above-mentioned background technology.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a soil penetration and damage test system for a foundation pit support and waterproofing system, including a preliminary adjustment module for a support structure, which is used to collect construction environment data of the target foundation pit support and waterproofing system construction area, make preliminary adjustments to the foundation pit support test parameters, and perform early warning processing.

[0008] The waterproof performance analysis module is used to carry out real-time monitoring of the soil penetration damage test of the foundation pit support test structure after preliminary adjustment, and obtain the waterproof performance analysis results of the foundation pit support test structure.

[0012] Based on the construction environment data of the target foundation pit support and waterproofing system construction area, the construction environment anomaly assessment value of the target foundation pit support and waterproofing system construction area is processed to obtain the construction environment anomaly assessment value of the target foundation pit support and waterproofing system construction area, and the construction environment anomaly assessment value of the target foundation pit support and waterproofing system construction area is used to quantify the stability of the construction environment soil and support structure.

[0013] Furthermore, the preliminary adjustment of the foundation pit support test parameters and early warning processing are carried out. The specific process is: comparing the construction environment abnormality assessment value of the target foundation pit support waterproofing system construction area with the set construction environment abnormality assessment threshold to obtain a preliminary adjustment result, and the preliminary adjustment result includes executing the preliminary adjustment and not executing the preliminary adjustment.

[0014] If the construction environment abnormality assessment value of the target foundation pit support and waterproofing system construction area is lower than or equal to the set construction environment abnormality assessment threshold, the preliminary adjustment result will be marked as not executing preliminary adjustment, and the soil penetration and damage test will continue to be carried out with the current foundation pit support test duration period; otherwise, the preliminary adjustment result will be marked as executing preliminary adjustment, and the difference between the construction environment abnormality assessment value of the target foundation pit support and waterproofing system construction area and the set construction environment abnormality assessment threshold will be recorded as the foundation pit support test adjustment control value.

[0015] The duration of the foundation pit support test is obtained according to the foundation pit support test adjustment control value, and a preliminary adjustment of the duration of the foundation pit support test is performed, and the preliminary adjustment result is sent to the management terminal for early warning.

[0016] Furthermore, the soil seepage destruction test of the foundation pit support test structure after the preliminary adjustment is monitored in real time. The specific process is: the soil seepage destruction test of the foundation pit support test structure after the preliminary adjustment is monitored in real time, and the soil seepage data of the foundation pit support test structure is counted. The soil seepage data of the foundation pit support test structure includes the seepage rate, pore water pressure and seepage water flow rate of the foundation pit support test structure.

[0017] A comprehensive analysis is performed on the soil permeability data of the foundation pit support test structure to obtain a waterproof performance evaluation value of the foundation pit support test structure, and the waterproof performance evaluation value of the foundation pit support test structure is used to quantify the waterproof effect of the foundation pit support test structure.

[0018] Furthermore, the waterproof performance analysis result of the foundation pit support test structure is obtained, and the specific process is: the waterproof performance analysis result of the foundation pit support test structure includes qualified waterproof performance and unqualified waterproof performance.

[0019] The waterproof performance evaluation value of the foundation pit support test structure is compared with the set waterproof performance evaluation threshold. If the waterproof performance evaluation value of the foundation pit support test structure is higher than or equal to the set waterproof performance evaluation threshold, the waterproof performance analysis result of the foundation pit support test structure is marked as qualified waterproof performance; otherwise, the waterproof performance analysis result of the foundation pit support test structure is marked as unqualified waterproof performance.

[0020] Furthermore, the synchronous monitoring of the support structure of the foundation pit support test structure specifically involves the following process: collecting support structure data of the foundation pit support test structure, wherein the support structure data of the foundation pit support test structure include the average displacement of the support structure of the foundation pit support test structure, the average inclination angle of the support structure, the average number of cracks in the support structure and the pore water pressure.

[0021] A comprehensive analysis is performed based on the support structure data of the foundation pit support test structure to obtain a support structure evaluation value of the foundation pit support test structure, and the support structure evaluation value of the foundation pit support test structure is used to quantify the overall stability of the foundation pit support test structure under the influence of external environmental factors.

[0022] Furthermore, the analysis obtains a support structure analysis result of the foundation pit support test structure, and the specific process is: the support structure analysis result of the foundation pit support test structure includes a qualified support structure and an unqualified support structure.

[0023] The support structure evaluation value of the foundation pit support test structure is compared with the set support structure evaluation threshold. If the support structure evaluation value of the foundation pit support test structure is higher than or equal to the set support structure evaluation threshold, the support structure analysis result of the foundation pit support test structure is marked as a qualified support structure; otherwise, the support structure analysis result of the foundation pit support test structure is marked as an unqualified support structure.

[0024] Furthermore, the optimization early warning and monitoring configuration of the soil penetration damage test are specifically performed as follows: extracting the waterproof performance analysis results of the foundation pit support test structure and the support structure analysis results of the foundation pit support test structure; if the waterproof performance analysis result of the foundation pit support test structure is that the waterproof performance is qualified, then continue to perform data monitoring on the soil penetration damage test with the current data monitoring configuration; if the waterproof performance analysis result of the foundation pit support test structure is that the waterproof performance is unqualified, then perform data monitoring configuration on the soil penetration damage test according to the preset number of additional monitoring points, and send the waterproof performance analysis results to the management terminal for waterproof performance optimization early warning.

[0025] If the support structure analysis result of the foundation pit support test structure is that the support structure is qualified, the soil penetration damage test will continue to be monitored with the current support structure parameter configuration. If the support structure analysis result of the foundation pit support test structure is that the support structure is unqualified, the support structure analysis result will be sent to the management terminal for support structure optimization early warning.

[0026] Furthermore, the support structure evaluation value of the foundation pit support test structure is specifically analyzed under the following conditions:

[0027] Where α represents the support structure evaluation value of the foundation pit support test structure, A 1represents the average displacement of the supporting structure of the foundation pit supporting test structure, θ 1 It represents the correction factor corresponding to the set unit displacement of the supporting structure, A 2 represents the average inclination angle of the supporting structure of the foundation pit supporting test structure, θ 2 It represents the correction factor corresponding to the set unit support structure inclination angle, A 3 represents the average number of cracks in the supporting structure of the foundation pit supporting test structure, θ 3 It represents the correction factor corresponding to the set number of cracks in the unit support structure, A 4 represents the pore water pressure of the foundation pit support test structure, ΔA 4 represents the set defined pore water pressure, and e represents a natural constant.

[0029] The soil penetration damage test of the foundation pit support test structure after preliminary adjustment was monitored in real time to obtain the waterproof performance analysis results of the foundation pit support test structure.

[0030] The supporting structure of the foundation pit supporting test structure is monitored synchronously, and the supporting structure analysis results of the foundation pit supporting test structure are obtained through analysis.

[0031] According to the waterproof performance analysis results of the foundation pit support test structure and the support structure analysis results, optimized early warning is carried out and monitoring configuration of the soil penetration damage test is carried out.

[0032] The present invention has the following beneficial effects:

[0033] (1) The present invention provides a soil penetration and destruction test system and method for a foundation pit support and waterproofing system. First, the construction environment data of the target foundation pit support and waterproofing system construction area is collected and processed to improve the reliability of the soil penetration and destruction test. Then, the soil penetration and destruction test of the foundation pit support test structure after preliminary adjustment is monitored in real time, so that the permeability changes of the soil can be discovered in time.

[0036] (4) The present invention optimizes early warning and monitors the soil penetration damage test, which helps to reduce the impact of environmental interference on the soil penetration damage test. By combining the waterproof performance analysis results of the support structure, it can effectively reduce the construction risks caused by support structure failure or soil penetration problems, thereby improving the safety and stability of the construction process, effectively avoiding the safety hazards caused by penetration damage, and reducing the number of subsequent repairs and maintenance.

[0037] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Figure 1 It is a schematic diagram of system module connection of the present invention.

[0039] Figure 2 It is a schematic diagram of the method flow of the present invention. DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] See also Figure 1 As shown, an embodiment of the present invention provides a technical solution: a soil penetration and destruction test system for a foundation pit support and waterproofing system, including a preliminary adjustment module for a support structure, which is used to collect construction environment data of a target foundation pit support and waterproofing system construction area, make preliminary adjustments to foundation pit support test parameters, and perform early warning processing.

[0042] The waterproof performance analysis module is used to carry out real-time monitoring of the soil penetration damage test of the foundation pit support test structure after preliminary adjustment, and obtain the waterproof performance analysis results of the foundation pit support test structure.

[0043] The support structure analysis module is used to synchronously monitor the support structure of the foundation pit support test structure and obtain the support structure analysis results of the foundation pit support test structure.

[0044] The optimization warning configuration module is used to optimize the warning and monitor the soil penetration damage test according to the waterproof performance analysis results of the foundation pit support test structure and the support structure analysis results.

[0045] Specifically, the construction environment data of the target foundation pit support and waterproofing system construction area are collected, and the specific process is: the construction environment data of the target foundation pit support and waterproofing system construction area includes the average soil infiltration rate, the maximum groundwater level fluctuation, the average displacement of the support structure, the average pressure of the support structure and the average vibration frequency of the support structure.

[0046] It should be added that the support structure includes but is not limited to steel sheet pile support, anchor cables, retaining wall support, bracing rods and supporting trusses.

[0047] It should be noted that the construction environment data of the target foundation pit support and waterproofing system construction area is measured before the soil penetration damage test is carried out. The average soil penetration rate of the target foundation pit support and waterproofing system construction area refers to the ability of water to pass through the soil per unit time. The permeameter, water level meter, displacement sensor, pressure sensor and vibration sensor can be used to measure the soil penetration rate, groundwater level, average displacement of the support structure, support structure pressure and support structure vibration frequency of the target foundation pit support and waterproofing system construction area, and then the average soil penetration rate, maximum groundwater level fluctuation, average displacement of the support structure, average pressure of the support structure and average vibration frequency of the support structure in the target foundation pit support and waterproofing system construction area can be obtained.

[0048] It should be noted that the maximum fluctuation of groundwater level in the target area for constructing foundation pit support and waterproofing system usually refers to the difference between the maximum and minimum groundwater levels within a certain period of time. The groundwater level is measured regularly in monitoring wells around the target area for constructing foundation pit support and waterproofing system. Through historical data and continuous water level monitoring, the maximum fluctuation of groundwater level in the target area for constructing foundation pit support and waterproofing system can be obtained. The displacement of supporting structure in the target area for constructing foundation pit support and waterproofing system refers to the displacement relative to the initial position of the supporting structure itself. The average displacement of all supporting structures is taken to obtain the average displacement of supporting structure in the target area for constructing foundation pit support and waterproofing system.

[0049] Based on the construction environment data of the target foundation pit support and waterproofing system construction area, the construction environment anomaly assessment value of the target foundation pit support and waterproofing system construction area is processed to obtain the construction environment anomaly assessment value of the target foundation pit support and waterproofing system construction area, and the construction environment anomaly assessment value of the target foundation pit support and waterproofing system construction area is used to quantify the stability of the construction environment soil and support structure.

[0050] In this embodiment, the construction environment abnormality assessment value of the target foundation pit support waterproofing system construction area can be obtained by the following analysis method, and the specific analysis conditions are as follows:

[0051]

[0052] Where β represents the abnormal assessment value of the construction environment in the target foundation pit support and waterproofing system construction area, B 1 represents the average soil infiltration rate in the target foundation pit support and waterproofing system construction area, ΔB 1 represents the average infiltration rate of the defined soil, B 2 represents the maximum value of groundwater level fluctuation in the target foundation pit support and waterproofing system construction area, μ 2 Indicates the weight factor corresponding to the maximum value of the unit groundwater level fluctuation, B 3 represents the average displacement of the supporting structure in the target foundation pit support and waterproofing system construction area, μ 3 Indicates the weight factor corresponding to the set unit displacement of the supporting structure, B 4 represents the average pressure of the supporting structure in the target foundation pit support and waterproofing system construction area, μ 4 Indicates the weight factor corresponding to the set unit support structure pressure, B 5 represents the average vibration frequency of the support structure in the target foundation pit support and waterproofing system construction area, μ 5 It represents the weight factor corresponding to the set unit support structure vibration frequency, and e represents a natural constant.

[0053] It should be noted that a higher average soil infiltration rate means that water can more easily pass through the soil layer, which may cause large fluctuations in the water level in the foundation pit, affecting the stability of the foundation pit support structure and the abnormal construction environment assessment value. A larger maximum groundwater level fluctuation usually means that the groundwater changes more dramatically and the abnormal construction environment assessment value is also larger. The larger the average displacement of the support structure, the greater the problem of stress or deformation of the support structure, which will also lead to an increase in the abnormal construction environment assessment value. The greater the average pressure of the support structure, the more it indicates that the bearing capacity of the soil around the foundation pit may be insufficient and the abnormal construction environment assessment value is also larger. The greater the average vibration frequency of the support structure, the stronger the groundwater flow around the foundation pit, which may affect the stability of the support structure and increase the abnormal construction environment assessment value.

[0054] It should be added that, in this embodiment, the weight factor corresponding to the preset maximum value of the unit groundwater level fluctuation, the weight factor corresponding to the unit support structure displacement, the weight factor corresponding to the unit support structure pressure and the weight factor corresponding to the unit support structure vibration frequency are obtained from the seepage damage test database.

[0055] It should be explained that the weight factors corresponding to the maximum value of the unit groundwater level fluctuation, the unit support structure displacement, the unit support structure pressure and the unit support structure vibration frequency are respectively used to adjust the importance of the maximum value of the groundwater level fluctuation, the average displacement of the support structure, the average pressure of the support structure and the average vibration frequency of the support structure in the target foundation pit support and waterproofing system construction area in the process of analyzing and obtaining the abnormal construction environment assessment value. There is a pre-set mapping relationship between the real-time construction environment data of the target foundation pit support and waterproofing system construction area and the corresponding weight factors in the penetration damage test database. The pre-set mapping relationship can be used to match the weight factors corresponding to the real-time construction environment data of the target foundation pit support and waterproofing system construction area. For example, the maximum value of the groundwater level fluctuation, the average displacement of the support structure, the average pressure of the support structure and the average vibration frequency of the support structure in the target foundation pit support and waterproofing system construction area are matched with the pre-set mapping relationship to obtain the weight factors corresponding to the maximum value of the unit groundwater level fluctuation, the unit support structure displacement, the unit support structure pressure and the unit support structure vibration frequency.

[0056] In this implementation plan, the average soil infiltration rate, the maximum groundwater level fluctuation, the average displacement of the support structure, the average pressure of the support structure and the average vibration frequency of the support structure in the target foundation pit support and waterproofing system construction area are correlated and do not exist independently. For example, the maximum groundwater level fluctuation will affect the fluidity of the groundwater, thereby changing the permeability of the soil, and further affecting the overall performance of the foundation pit support and waterproofing system. When the average soil infiltration rate is high, the average displacement and average pressure of the support structure increase, and the severity of the water level fluctuation will aggravate the deformation and pressure concentration of the support structure. The high average vibration frequency of the support structure may have an adverse effect on the stability of the support structure. Comprehensive analysis of the construction environment abnormality assessment value of the target foundation pit support and waterproofing system construction area can more accurately assess the degree of abnormality of the construction environment in the target foundation pit support and waterproofing system construction area, achieve accurate assessment of the construction environment, and identify potential risk factors in the construction environment.

[0057] Specifically, preliminary adjustments are made to the foundation pit support test parameters and early warning processing is carried out. The specific process is: the construction environment anomaly assessment value of the target foundation pit support waterproofing system construction area is compared with the set construction environment anomaly assessment threshold to obtain preliminary adjustment results, which include executing preliminary adjustments and not executing preliminary adjustments.

[0058] If the construction environment abnormality assessment value of the target foundation pit support and waterproofing system construction area is lower than or equal to the set construction environment abnormality assessment threshold, the preliminary adjustment result will be marked as not executing preliminary adjustment, and the soil penetration and damage test will continue to be carried out with the current foundation pit support test duration period; otherwise, the preliminary adjustment result will be marked as executing preliminary adjustment, and the difference between the construction environment abnormality assessment value of the target foundation pit support and waterproofing system construction area and the set construction environment abnormality assessment threshold will be recorded as the foundation pit support test adjustment control value.

[0059] It should be added that the analysis of the construction environment data of the target foundation pit support and waterproofing system construction area can reflect the degree of abnormality of the construction environment in the target foundation pit support and waterproofing system construction area. If the degree of abnormality in the construction environment is large, conducting subsequent tests with the original default foundation pit support test duration period may cause inaccurate test results and even affect the safety of subsequent construction. Therefore, it is necessary to adjust the duration of the foundation pit support test accordingly based on the construction environment data of the target foundation pit support and waterproofing system construction area.

[0060] The duration of the foundation pit support test is obtained according to the foundation pit support test adjustment control value, and a preliminary adjustment of the duration of the foundation pit support test is performed, and the preliminary adjustment result is sent to the management terminal for early warning.

[0061] It should be added that the foundation pit support test duration is obtained according to the foundation pit support test adjustment control value matching. The specific process is to match the foundation pit support test adjustment control value with the foundation pit support test duration corresponding to each foundation pit support test adjustment control value interval stored in the penetration damage test database, and count the foundation pit support test duration corresponding to the interval where the foundation pit support test adjustment control value is located, which is recorded as the foundation pit support test duration.

[0062] Specifically, the soil penetration destruction test of the foundation pit support test structure after the preliminary adjustment is monitored in real time. The specific process is: the soil penetration destruction test of the foundation pit support test structure after the preliminary adjustment is monitored in real time, and the soil penetration data of the foundation pit support test structure is counted. The soil penetration data of the foundation pit support test structure includes the penetration rate, pore water pressure and penetration water flow rate of the foundation pit support test structure.

[0063] It should be noted that the pore water pressure of the foundation pit support test structure refers to the average pressure of water in the pores of the soil, and the infiltration water flow rate of the foundation pit support test structure is the average water flow rate through the soil during the test period. The infiltration rate, pore water pressure and infiltration water flow rate of the foundation pit support test structure can be measured respectively by using a permeameter, pore water pressure gauge and flow meter, thereby obtaining the infiltration rate, pore water pressure and infiltration water flow rate of the foundation pit support test structure.

[0064] A comprehensive analysis is performed on the soil permeability data of the foundation pit support test structure to obtain a waterproof performance evaluation value of the foundation pit support test structure, and the waterproof performance evaluation value of the foundation pit support test structure is used to quantify the waterproof effect of the foundation pit support test structure.

[0065] In this embodiment, the waterproof performance evaluation value of the foundation pit support test structure can be obtained by the following analysis method, and the specific analysis conditions are as follows:

[0066]

[0067] In the formula, γ represents the waterproof performance evaluation value of the foundation pit support test structure, D 1 represents the infiltration rate of the foundation pit support test structure, ω 1 Indicates the compensation factor corresponding to the set unit penetration rate, A 4 represents the pore water pressure of the foundation pit support test structure, ΔA 4 represents the set defined pore water pressure, D 3 represents the seepage water flow rate of the foundation pit support test structure, ω 3 Indicates the compensation factor corresponding to the set unit infiltration water flow rate.

[0068] It should be noted that the greater the infiltration rate of the foundation pit support test structure, the easier it is for moisture to enter the foundation pit support structure through the soil, which means that the waterproofness of the soil is poor, and the waterproof performance evaluation value of the foundation pit support test structure is also smaller. If the pore water pressure is too high, it may cause instability of the soil, and then affect the overall stability and waterproof effect of the foundation pit support structure. The smaller the waterproof performance evaluation value of the foundation pit support test structure is, the larger the infiltration water flow rate is, indicating that water infiltration is relatively rapid, the waterproof performance of the soil is weak, and the waterproof performance evaluation value of the foundation pit support test structure is also smaller.

[0069] It should be added that, in this embodiment, the preset compensation factor corresponding to the unit infiltration rate and the compensation factor corresponding to the unit infiltration water flow rate are obtained from the infiltration damage test database.

[0070] It needs to be explained that the compensation factors corresponding to the unit infiltration rate and the unit infiltration water flow rate are respectively used to adjust the importance of the infiltration rate and the infiltration water flow rate of the foundation pit support test structure in the process of analyzing and obtaining the waterproof performance evaluation value. There is a pre-set mapping relationship between the real-time soil infiltration data of the foundation pit support test structure and the corresponding compensation factor in the infiltration damage test database. The real-time soil infiltration data of the foundation pit support test structure can be matched to obtain the compensation factor corresponding to the soil infiltration data of the foundation pit support test structure through the pre-set mapping relationship. For example, the infiltration rate and the infiltration water flow rate of the foundation pit support test structure are respectively matched with the pre-set mapping relationship to obtain the compensation factors corresponding to the unit infiltration rate and the unit infiltration water flow rate.

[0071] In this implementation scheme, the infiltration rate, pore water pressure and infiltration water flow of the foundation pit support test structure are correlated and do not exist independently. The relationship between these parameters reflects the overall permeability characteristics of the soil. For example, the higher the pore water pressure of the foundation pit support test structure, the more the pore water pressure drives the flow of water through the soil, and the greater the infiltration rate. When the infiltration rate of the soil increases or the pore water pressure rises, the infiltration water flow will also increase. Comprehensive analysis can obtain the waterproof performance evaluation value of the foundation pit support test structure, which can more accurately evaluate the waterproof performance of the foundation pit support test structure and more comprehensively reflect the infiltration behavior of the soil under different working conditions.

[0072] Specifically, the waterproof performance analysis result of the foundation pit support test structure is obtained, and the specific process is: the waterproof performance analysis result of the foundation pit support test structure includes qualified waterproof performance and unqualified waterproof performance.

[0073] The waterproof performance evaluation value of the foundation pit support test structure is compared with the set waterproof performance evaluation threshold. If the waterproof performance evaluation value of the foundation pit support test structure is higher than or equal to the set waterproof performance evaluation threshold, the waterproof performance analysis result of the foundation pit support test structure is marked as qualified waterproof performance; otherwise, the waterproof performance analysis result of the foundation pit support test structure is marked as unqualified waterproof performance.

[0074] Specifically, the supporting structure of the foundation pit support test structure is monitored synchronously, and the specific process is: collecting the supporting structure data of the foundation pit support test structure, the supporting structure data of the foundation pit support test structure includes the average displacement of the supporting structure of the foundation pit support test structure, the average inclination angle of the supporting structure, the average number of cracks in the supporting structure and the pore water pressure.

[0075] It should be noted that the average inclination angle of the support structure and the number of cracks in the support structure of the foundation pit support test structure can be measured using an inclinometer and a crack detector respectively, thereby obtaining the average inclination angle of the support structure and the average number of cracks in the support structure of the foundation pit support test structure.

[0076] It should be noted that the inclination angle of the support structure of the foundation pit support test structure refers to the degree of inclination of the foundation pit support wall or supporting member during the construction process or after being subjected to force. This inclination angle is measured relative to the initial angle of the support structure itself. The average inclination angle of all support structures is taken to obtain the average inclination angle of the support structure of the foundation pit support test structure.

[0077] A comprehensive analysis is performed based on the support structure data of the foundation pit support test structure to obtain a support structure evaluation value of the foundation pit support test structure, and the support structure evaluation value of the foundation pit support test structure is used to quantify the overall stability of the foundation pit support test structure under the influence of external environmental factors.

[0078] Specifically, the support structure assessment value of the foundation pit support test structure is analyzed under the following conditions:

[0079]

[0080] Where α represents the support structure evaluation value of the foundation pit support test structure, A 1 represents the average displacement of the supporting structure of the foundation pit supporting test structure, θ 1 It represents the correction factor corresponding to the set unit displacement of the supporting structure, A 2 represents the average inclination angle of the supporting structure of the foundation pit supporting test structure, θ 2 It represents the correction factor corresponding to the set unit support structure inclination angle, A 3 represents the average number of cracks in the supporting structure of the foundation pit supporting test structure, θ 3 It represents the correction factor corresponding to the set number of cracks in the unit support structure, A 4 represents the pore water pressure of the foundation pit support test structure, ΔA 4 represents the set defined pore water pressure, and e represents a natural constant.

[0081] It should be noted that the larger the average displacement of the support structure and the average inclination angle of the support structure of the foundation pit support test structure, the more unstable the support structure is, and the smaller the support structure evaluation value of the foundation pit support test structure is. Excessive pore water pressure may increase the fluidity of the soil and reduce the stability of the structure.

[0082] It should be added that, in this embodiment, the correction factor corresponding to the preset unit support structure displacement, the correction factor corresponding to the unit support structure inclination angle and the correction factor corresponding to the number of cracks in the unit support structure are obtained from the penetration damage test database.

[0083] It needs to be explained that the correction factors corresponding to the unit support structure displacement, the unit support structure inclination angle and the unit support structure crack number are respectively used to adjust the importance of the average displacement of the support structure, the average inclination angle of the support structure and the average number of cracks in the support structure of the foundation pit support test structure in the process of analyzing the support structure evaluation value. There is a pre-set mapping relationship between the real-time support structure data of the foundation pit support test structure and the corresponding correction factors in the penetration damage test database. The correction factors corresponding to the support structure data of the real-time foundation pit support test structure can be matched through the pre-set mapping relationship. For example, the average displacement of the support structure, the average inclination angle of the support structure and the average number of cracks in the support structure of the foundation pit support test structure are matched with the pre-set mapping relationship to obtain the correction factors corresponding to the unit support structure displacement, the unit support structure inclination angle and the unit support structure crack number.

[0084] In this implementation scheme, there is a correlation between the average displacement of the support structure, the average inclination angle of the support structure, the average number of cracks in the support structure and the pore water pressure of the foundation pit support test structure, and they do not exist independently. For example, when the average displacement of the support structure is large, the support structure undergoes a larger displacement and the inclination angle may also increase. When the average displacement of the support structure increases or the average inclination angle increases, cracks may appear in the support structure, and the average number of cracks in the support structure will also increase. The change in pore water pressure reflects the hydrological conditions of the soil around the foundation pit. The increase in pore water pressure will affect the stability of the support structure. Comprehensive analysis can obtain the support structure evaluation value of the foundation pit support test structure, which can more accurately evaluate the stability of the foundation pit support test structure.

[0085] Specifically, the support structure analysis result of the foundation pit support test structure is analyzed and obtained, and the specific process is: the support structure analysis result of the foundation pit support test structure includes a qualified support structure and an unqualified support structure.

[0086] The support structure evaluation value of the foundation pit support test structure is compared with the set support structure evaluation threshold. If the support structure evaluation value of the foundation pit support test structure is higher than or equal to the set support structure evaluation threshold, the support structure analysis result of the foundation pit support test structure is marked as a qualified support structure; otherwise, the support structure analysis result of the foundation pit support test structure is marked as an unqualified support structure.

[0087] Specifically, optimization and early warning are carried out and monitoring and configuration of the soil penetration and damage test are carried out. The specific process is: extract the waterproof performance analysis results of the foundation pit support test structure and the support structure analysis results of the foundation pit support test structure. If the waterproof performance analysis result of the foundation pit support test structure is that the waterproof performance is qualified, then continue to monitor the soil penetration and damage test with the current data monitoring configuration. If the waterproof performance analysis result of the foundation pit support test structure is that the waterproof performance is unqualified, then according to the preset number of monitoring points, data monitoring configuration of the soil penetration and damage test is added, and the waterproof performance analysis results are sent to the management terminal for waterproof performance optimization and early warning.

[0088] It should be added that the analysis of the soil permeability data of the foundation pit support test structure can reflect the waterproof performance of the foundation pit support test structure. If the waterproof performance is unqualified and subsequent construction is carried out with the original default data monitoring configuration, it may result in low waterproof performance of the foundation pit support. Therefore, it is necessary to adjust the foundation pit support waterproof system according to the soil permeability data of the foundation pit support test structure, and then re-test and make corresponding adjustments to the foundation pit support test monitoring points.

[0089] If the support structure analysis result of the foundation pit support test structure is that the support structure is qualified, the soil penetration damage test will continue to be monitored with the current support structure parameter configuration. If the support structure analysis result of the foundation pit support test structure is that the support structure is unqualified, the support structure analysis result will be sent to the management terminal for support structure optimization early warning.

[0090] It should be added that the analysis of the support structure data of the foundation pit support test structure can reflect the support structure stability of the foundation pit support test structure. If the support structure stability is unqualified and the subsequent construction is carried out with the original default foundation pit support structure, it may cause unstable construction safety. Therefore, it is necessary to remind the need to adjust the foundation pit support structure based on the support structure data of the foundation pit support test structure.

[0091] like Figure 2 The second aspect of the present invention provides a soil penetration damage test method for a foundation pit support and waterproofing system, comprising: collecting construction environment data of a target foundation pit support and waterproofing system construction area, making preliminary adjustments to foundation pit support test parameters, and performing early warning processing.

[0092] The soil penetration damage test of the foundation pit support test structure after preliminary adjustment was monitored in real time to obtain the waterproof performance analysis results of the foundation pit support test structure.

[0093] The supporting structure of the foundation pit supporting test structure is monitored synchronously, and the supporting structure analysis results of the foundation pit supporting test structure are obtained through analysis.

[0094] According to the waterproof performance analysis results of the foundation pit support test structure and the support structure analysis results, optimized early warning is carried out and monitoring configuration of the soil penetration damage test is carried out.

[0095] It should be noted that a soil penetration damage test system and method for a foundation pit support and waterproofing system also includes a penetration damage test database for storing a first parameter set, a second parameter set and a third parameter set obtained by analyzing historical data.

[0096] The first parameter set includes the definition of the average soil infiltration rate, the weight factor corresponding to the maximum unit groundwater level fluctuation, the weight factor corresponding to the unit support structure displacement, the weight factor corresponding to the unit support structure pressure, the weight factor corresponding to the unit support structure vibration frequency, the construction environment abnormality assessment threshold and the foundation pit support test duration corresponding to the adjustment control value interval of each foundation pit support test.

[0097] The second parameter set includes a compensation factor corresponding to a unit infiltration rate, a defined pore water pressure, a compensation factor corresponding to a unit infiltration water flow rate, and a threshold for evaluating waterproof performance.

[0098] The third parameter set includes the correction factor corresponding to the unit support structure displacement, the correction factor corresponding to the unit support structure inclination angle, the correction factor corresponding to the unit support structure crack number, the support structure assessment threshold and the number of additional monitoring points.

[0099] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
