[0018] Embodiment 1
[0019] like Figure 1 As shown, the embodiment of the present application provides a method for early warning of deformation risk of underground pipe gallery structure, wherein the method comprises:
[0020] Deformation information of the underground pipe gallery structure is obtained, where the deformation information includes a deformation position.
[0021] Deformation sensors (such as strain gauges, displacement meters, etc.) are installed at key locations of underground pipe corridors. These sensors can monitor and record the deformation information of the structure in real time. The deformation information usually includes the deformation location, which is used to assess the health status and potential risks of underground pipe corridors. High-definition cameras or other detection equipment carried by drones are used to inspect the exterior or accessible parts of underground pipe corridors. By taking photos or videos, possible signs of deformation, such as cracks and dislocations, can be identified.
[0022] Furthermore, the deformation information of the underground pipe gallery structure is obtained, including:
[0023] The underground pipe gallery structure is scanned as a whole to obtain structural status data; abnormal features are extracted from the structural status data, and the deformation information is generated according to the abnormal feature extraction results.
[0024] Preferably, use advanced scanning technologies (such as lidar scanning, 3D laser scanning, photogrammetry, etc.) to conduct an overall scan of the underground utility tunnel structure. These technologies can generate high-precision 3D models, reflecting the geometric shape and details of the utility tunnel structure. Through the overall scan, structural state data of the underground utility tunnel structure can be obtained. The structural state data includes geometric dimensions such as pipe diameter, wall thickness, length, etc., surface states such as abnormal features like cracks, spalling, bulging, etc., and material information such as pipe material, coating condition, etc. After obtaining the structural state data, the next step is to extract abnormal features. Abnormal features usually refer to obvious changes or deviations in the structure compared with the normal state. Specifically, for the scanned image data, image processing technologies (such as edge detection, texture analysis, image segmentation, etc.) can be used to identify abnormal features such as cracks and bulges; for numerical data (such as geometric dimensions, material information, etc.), methods such as statistical analysis and machine learning can be used to detect outliers. According to the results of abnormal feature extraction, deformation information of the underground utility tunnel structure is generated. The deformation information usually includes deformation position, deformation amount, deformation type (such as elastic deformation, plastic deformation, etc.).
[0025] Perform digital modeling on the underground utility tunnel structure to establish a digital model.
[0026] The digital model can provide a detailed view of the structure. Digital modeling of the underground utility tunnel structure is carried out to ensure accurate monitoring. According to the detailed data of the underground utility tunnel structure, use modeling software to conduct digital modeling to obtain the digital model of the underground utility tunnel structure.
[0027] Based on the deformation position, perform deformation marking in the digital model to obtain deformation type identification and deformation level identification.
[0028] In the digital model of the underground utility tunnel structure, based on the obtained deformation position information, perform deformation type identification and deformation level identification. Specifically, according to the deformation position information, determine the specific positions where deformation occurs in the digital model of the underground utility tunnel structure, such as key parts like pipes, brackets, connection points, etc.; according to the deformation characteristics, determine the deformation type identification, and further evaluate the severity or level of the deformation. By comparing the deformation amount with a preset threshold and analyzing the impact of the deformation on the structural performance, the deformation level is then determined. Use different markings to perform deformation type identification and deformation level identification at the deformation position.
[0029] Use the digital model to conduct deformation simulation to obtain deformation limit nodes, and obtain the structural state data of the deformation limit nodes.
[0030] Furthermore, the structural state data includes but is not limited to displacement data, stress data, deformation data, environmental data, and material property data.
[0031] Perform deformation simulation using the digital model of the underground pipe gallery structure to simulate the deformation of the underground pipe gallery structure under different conditions, including different types of simulations such as static analysis, dynamic analysis, and temperature field analysis. According to the simulation results, analyze the deformation distribution and trend of the structure to find the nodes where the deformation value exceeds the preset threshold, that is, the nodes with excessive deformation. For each node with excessive deformation, extract the structural state data of the node with excessive deformation, including but not limited to displacement data, stress data, deformation data, environmental data, and material property data. Among them, the displacement data describes the position change of the structure under the action of external loads or internal stresses; the stress data reflects the magnitude and direction of the forces acting on each point inside the structure; the deformation data describes the shape change of the structure under the action of external loads or internal stresses, including different types of deformations such as bending, twisting, and expansion; the environmental data involves external environmental factors that affect the structural performance, such as temperature, humidity, soil pressure, and groundwater level; the material property data describes the basic physical and mechanical properties of the materials that make up the structure, such as elastic modulus, yield strength, and fracture toughness.
[0032] Construct an association rule model based on the deformation type identifier, the deformation level identifier, and the structural state data.
[0033] Based on the deformation type identifier, the deformation level identifier, and the structural state data, an association rule model can be constructed, and the association rule model can reveal the potential associations and patterns between these identifiers and the structural state data.
[0034] Furthermore, constructing an association rule model based on the deformation type identifier, the deformation level identifier, and the structural state data includes:
[0035] Obtain multiple deformation levels, divide the structural state data based on the multiple deformation levels to obtain a deformation limit information table; analyze the deformation limit information table through an association rule mining algorithm to obtain the association rule model.
[0036] In the monitoring of the underground pipe gallery structure, after obtaining multiple deformation levels, the structural state data can be classified according to these deformation levels, and further a deformation limit exceeded information table can be generated. Then, the association rule mining algorithm is used to analyze this information table to construct an association rule model. Specifically, multiple deformation levels are obtained, such as primary deformation, secondary deformation, tertiary deformation, etc. Each level corresponds to a different severity of deformation. For example, in the case of bending, the primary level only shows a slight trend, the secondary level results in bending, and the tertiary level leads to direct fracture. Based on historical data and expert experience, the structural state data (such as displacement, stress, deformation, etc.) of each monitoring point is matched with the corresponding deformation level. According to the matching results, the structural state data is classified into different deformation level categories. The deformation limit exceeded information table includes monitoring point information, deformation level, structural state data (such as displacement value, stress value, etc.). According to the classified structural state data, the corresponding information is filled into the deformation limit exceeded information table. The data of each monitoring point at different time points should be recorded. According to the characteristics and requirements of the data, a suitable association rule mining algorithm, such as the Apriori algorithm, the FP-Growth algorithm, etc., is selected to perform necessary preprocessing on the deformation limit exceeded information table, such as data cleaning, transformation, etc., to meet the requirements of the selected algorithm. For the selected association rule mining algorithm, necessary parameters are set, such as minimum support, minimum confidence, etc. The deformation limit exceeded information table is used as input data to run the association rule mining algorithm. The algorithm will analyze the patterns in the data and generate a series of association rules, which will constitute the association rule model.
[0037] According to the association rule model, deformation risk warning information of the underground pipe gallery structure is obtained.
[0038] The structural state data of the underground pipe gallery structure is input into the association rule model. The association rule model will, according to the association rules, identify the deformation level or risk level corresponding to the current structural state data. According to the deformation level or risk level output by the association rule model and in combination with a preset risk threshold, deformation risk warning information is generated. The warning information may include warning levels (such as primary warning, secondary warning, etc.), warning areas (specific to which section of the pipe gallery or which monitoring point), warning reasons (such as displacement exceeding the standard, stress concentration, etc.), and recommended countermeasures.
[0039] Furthermore, the method further includes:
[0040] Taking the standard underground pipe gallery structure as the target, repair prediction is carried out on the underground pipe gallery structure, including:
[0041] Conducting a process flow inspection on the underground pipe gallery structure to determine the process flow to be repaired;
[0042] Based on the process flow to be repaired, predict the repair difficulty, repair cost, and repair effect, and obtain the predicted repair difficulty coefficient, predicted repair cost coefficient, and predicted repair effect coefficient as the repair prediction results;
[0043] Perform repair adjustment based on the repair prediction results.
[0044] Taking the standard underground utility tunnel structure as the target, conduct repair prediction and perform repair adjustment accordingly. Specifically, conduct a comprehensive inspection of the process flow of the underground utility tunnel structure, including but not limited to inspections of pipelines, equipment, connectors, support structures, etc., to determine the process flow to be repaired; based on the specific situation and historical data of the process flow to be repaired, use a prediction model to predict the repair difficulty, repair cost, and repair effect, and obtain the predicted repair difficulty coefficient, predicted repair cost coefficient, and predicted repair effect coefficient as the repair prediction results; perform repair adjustment according to the repair prediction results.
[0045] Furthermore, performing repair adjustment based on the repair prediction results includes:
[0046] Input the predicted repair difficulty coefficient, predicted repair cost coefficient, and predicted repair effect coefficient into the repair adjustment evaluation model, and output the repair adjustment evaluation coefficient;
[0047] If the repair adjustment evaluation coefficient meets the repair adjustment constraints, perform repair adjustment based on the process flow to be repaired;
[0048] Otherwise, abandon the repair and retrieve the structure replacement plan.
[0049] The repair adjustment evaluation model is constructed based on the repair adjustment evaluation function and can comprehensively evaluate the feasibility, economy, and effect of the repair strategy. Input the repair difficulty coefficient, repair cost coefficient, and repair effect coefficient as input data into the repair adjustment evaluation model. The repair adjustment evaluation model calculates and evaluates based on the input predicted coefficients and outputs a repair adjustment evaluation coefficient. According to the preset repair adjustment constraint conditions, determine whether the repair adjustment evaluation coefficient meets the requirements. Among them, the repair adjustment constraint conditions may include the upper limit of the repair difficulty coefficient, the budget limit of the repair cost coefficient, the minimum requirement of the repair effect coefficient, etc. If the repair adjustment evaluation coefficient meets the repair adjustment constraint conditions, perform repair adjustment according to the process flow to be repaired. If it does not meet the repair adjustment constraint conditions, abandon the repair of this process flow and retrieve the structure replacement plan.
[0050] Furthermore, the repair adjustment evaluation model includes a repair adjustment evaluation function, and the repair adjustment evaluation function is as follows:
[0051]
[0052] Among them, R re is the repair adjustment evaluation coefficient, w eff , w dif , w co are the weight values, and their sum is 1. R eff is the predicted repair effect coefficient, R dif is the predicted repair difficulty coefficient, R co is the predicted repair cost coefficient.
[0053] The repair adjustment evaluation model includes a repair adjustment evaluation function. Among them, R re is the repair adjustment evaluation coefficient, w eff , w dif , w co are the weight values, and their sum is 1. R eff is the predicted repair effect coefficient, which is a value between 0 and 1. The larger the value, the better the repair effect; R dif is the predicted repair difficulty coefficient, which is a value between 0 and 1. The larger the value, the greater the repair difficulty; R co is the predicted repair cost coefficient, which is a value between 0 and 1. The larger the value, the higher the repair cost. The repair adjustment evaluation coefficient R re will comprehensively consider the repair effect, repair difficulty, and repair cost. If the repair effect is good and the repair difficulty and cost are low, then R re is larger, indicating that this is a relatively ideal repair adjustment plan. On the contrary, if the repair effect is poor, the repair difficulty is high, or the repair cost is high, then R re is smaller, indicating that this repair adjustment plan may not be the best choice.
[0054] In summary, the embodiments of the present application have at least the following technical effects:
[0055] First, obtain the deformation information of the underground pipe gallery structure, and the deformation information includes the deformation position. Then, perform digital modeling on the underground pipe gallery structure to establish a digital model. Based on the deformation position, perform deformation marking in the digital model to obtain the deformation type identifier and deformation level identifier. Next, use the digital model to perform deformation simulation to obtain the deformation limit nodes and obtain the structural state data of the deformation limit nodes. According to the deformation type identifier, deformation level identifier, and structural state data, construct an association rule model. Finally, according to the association rule model, obtain the deformation risk warning information of the underground pipe gallery structure. It solves the technical problem in the prior art that it is difficult to accurately warn of the deformation risk of the underground pipe gallery structure, resulting in the difficulty of timely discovery and handling of potential safety hazards, and achieves the technical effect of accurately warning of the deformation risk of the underground pipe gallery structure and improving the safety and reliability of the underground pipe gallery structure.
