[0017] Embodiment 1

[0018] like Figure 1 As shown, the present application provides a tunnel construction monitoring method based on parallel construction superposition effect analysis, the method comprising:

[0019] P10: Collect multiple construction information superimposed in parallel construction, where each construction information includes construction type and construction parameters, and the multiple construction information includes tunnel construction information and near-tunnel construction information;

[0020] It should be understood that during the parallel construction process, information on multiple construction behaviors that are carried out simultaneously is collected, and each construction information includes construction type and construction parameters, such as pile foundation construction, foundation pit excavation, TRD construction, etc. The construction parameters refer to the parameters of each construction behavior, such as pile foundation burial depth, foundation pit size, etc. And the multiple construction information includes tunnel construction information and near-tunnel construction information, that is, construction information inside the tunnel and construction information outside the tunnel. Construction inside the tunnel, such as excavation, support, reinforcement, etc., and construction outside the tunnel, such as on-ground buildings, roads, railways, earthwork accumulation, etc., will cause deformation and displacement of the tunnel due to additional loads.

[0021] P20: According to the multiple construction information, respectively analyze the stress field of the tunnel to obtain multiple stress field information;

[0022] Furthermore, step P20 of the embodiment of the present application also includes:

[0023] P21: Based on multiple sample construction types, multiple sample construction information sets are obtained, and multiple construction stress field sets are obtained;

[0024] P22: Multiple sample construction information sets and multiple construction stress field sets are used to construct multiple stress field analysis branches;

[0025] P23: Integrate multiple stress field analysis branches to obtain stress field analysis channels;

[0026] P24: Obtain the multiple stress field information, wherein the multiple stress field information is obtained by inputting multiple construction information into the stress field analysis channel.

[0027] Optionally, based on tunnel construction experience, multiple sample construction types are collected, such as excavation, support, reinforcement in the tunnel, and earthwork accumulation outside the tunnel, and then construction information is collected for multiple sample construction types to obtain multiple sample construction information sets, and the construction stress field information corresponding to the corresponding sample construction information is collected, that is, according to parameters such as construction type and construction scale, the stress field generated during construction is analyzed to obtain multiple construction stress field sets. Further, multiple sample construction information sets and multiple construction stress field sets are used as training data, combined with machine learning principles, such as BP neural network, to construct multiple stress field analysis branches, and supervised training is performed using the training data until all the multiple stress field analysis branches converge, wherein each stress field analysis branch corresponds to a sample construction type.

[0028] Furthermore, the multiple stress field analysis branches are merged to form a stress field analysis channel, and then the multiple construction information are input into the stress field analysis channel for stress analysis. The multiple stress field information is obtained, which can reflect the stress distribution of multiple construction behaviors currently being carried out simultaneously.

[0029] P30: Collecting the design information of the tunnel, constructing a tunnel twin model, and dividing it to obtain a multi-layer tunnel twin sub-model;

[0030] Furthermore, step P30 of the embodiment of the present application further includes:

[0031] P31: Obtain the structural design information of the tunnel;

[0032] P32: constructing a tunnel twin model of the tunnel according to the structural design information;

[0033] P33: Divide the tunnel twin model according to the radial direction of the tunnel to obtain a multi-layer twin sub-model.

[0034] Exemplarily, the structural design information of the current tunnel is collected, including structural data such as tunnel line selection, longitudinal section design, cross section design, and auxiliary tunnel design. Then, through three-dimensional simulation technology, three-dimensional simulation modeling is performed in combination with the design information to construct a tunnel twin model. Furthermore, according to the radial direction of the tunnel, that is, the extension direction of the tunnel, the tunnel twin model is divided into multiple segmented models to obtain a multi-layer twin sub-model. Through the multi-layer twin sub-model, the influence of stress on tunnel deformation and displacement can be analyzed in different zones.

[0035] P40: Based on the multi-layer tunnel twin model, the multiple stress field information are divided into stress fields, and tunnel offset information is analyzed respectively to obtain multiple tunnel offset information sets;

[0036] Further, such as Figure 2 As shown, step P40 of the embodiment of the present application also includes:

[0037] P41: Dividing the multiple stress field information according to the range of the multi-layer twin model to obtain multiple levels of stress field information sets, each of which includes multiple levels of stress field information received by each layer of the tunnel twin model;

[0038] P42: Building a tunnel offset analyzer;

[0041] P42-2: Use the multiple sample level stress field information sets and the multiple sample tunnel offset information sets respectively to construct multiple tunnel offset analysis branches and obtain a tunnel offset analyzer.

[0042] P43: Based on the tunnel offset analyzer, tunnel offset analysis is performed according to the multiple levels of stress field information sets to obtain multiple tunnel offset information sets.

[0043] Specifically, the multiple stress field information are divided according to the range of the multi-layer twin model, and multiple stress field information of each sub-model under multiple parallel construction behaviors are obtained to form multiple hierarchical stress field information sets, wherein each hierarchical stress field information set contains multiple hierarchical stress field information of each layer of tunnel twin model. Furthermore, for the multi-layer tunnel twin model, multiple sample hierarchical stress field information are collected according to the hierarchy, thereby forming multiple sample hierarchical stress field information sets, and multiple sample tunnel offset information sets are obtained, wherein the tunnel offset information refers to the direction and amplitude of tunnel deformation and displacement, and each sample tunnel offset information set contains multiple tunnel offset information of a tunnel twin model.

[0044] Further, the multiple sample hierarchical stress field information sets and multiple sample tunnel offset information sets are respectively used as construction data, combined with the principle of machine learning, to construct and train multiple tunnel offset analysis branches, each tunnel offset analysis branch corresponds to a tunnel twin model, and then the tunnel offset analyzer is composed of multiple tunnel offset analysis branches. Further, the multiple hierarchical stress field information sets are input into the tunnel offset analyzer, tunnel offset analysis is performed, and multiple tunnel offset information sets corresponding to the multi-layer tunnel twin model are output, and the multiple tunnel offset information sets can reflect the offset deformation of various parts of the current tunnel under the influence of different stress fields.

[0045] P50: Based on multiple tunnel offset information sets, tunnel offset superposition analysis is performed to obtain multiple superimposed tunnel offset information of the multi-layer tunnel twin model;

[0046] Furthermore, step P50 of the embodiment of the present application also includes:

[0047] P51: In a first tunnel twin submodel in the multi-layer tunnel twin submodel, based on a first tunnel offset information set, performing tunnel offset superposition analysis to obtain first superposition tunnel offset information;

[0048] P52: Continue to perform tunnel offset superposition analysis based on multiple tunnel offset information sets to obtain multiple superimposed tunnel offset information.

[0049] It should be understood that based on multiple tunnel offset information sets, tunnel offset superposition analysis is performed, that is, the offset information generated by multiple stress fields on a single tunnel twin model is superimposed and analyzed as the overall tunnel offset information in the single tunnel twin model. For example, any tunnel twin model is randomly selected as the first tunnel twin model in the multi-layer tunnel twin model, and the first tunnel offset information set corresponding to the first tunnel twin model is extracted from multiple tunnel offset information sets, and all offset information in the first tunnel offset information set is superimposed and calculated, such as tunnel displacement superposition, to obtain the first superimposed tunnel offset information, and so on, continue to perform offset superposition analysis of other tunnel twin models based on multiple tunnel offset information sets to obtain multiple superimposed tunnel offset information, which can reflect the offset deformation of various parts of the current tunnel under the joint influence of multiple stress fields.

[0050] P60: Based on multiple superimposed tunnel offset information, tunnel construction deformation analysis is performed to obtain multiple tunnel deformation modes, and the tunnel deformation mode with the largest proportion is output as the construction monitoring result.

[0051] Further, such as Figure 3 As shown, step P60 of the embodiment of the present application also includes:

[0052] P61: Based on the multi-layer tunnel twin model, multiple sample superimposed tunnel offset information sets are obtained, and multiple sample tunnel deformation mode sets are obtained;

[0053] P62: Using the multiple sample superimposed tunnel offset information sets and the multiple sample tunnel deformation pattern sets, construct multiple tunnel deformation pattern classification branches to obtain a tunnel deformation pattern classifier;

[0054] P63: Inputting the multiple superimposed tunnel offset information into a tunnel deformation pattern classifier to obtain multiple tunnel deformation patterns;

[0055] P64: Output the tunnel deformation mode with the largest proportion and obtain the construction monitoring result.

[0056] Optionally, tunnel construction deformation analysis is performed based on multiple superimposed tunnel offset information to obtain multiple tunnel deformation patterns, where the tunnel deformation pattern refers to the tunnel deformation category, and the tunnel deformation category with the greatest possibility of occurrence is selected for construction monitoring. The tunnel construction deformation analysis needs to be processed by a tunnel deformation pattern classifier, and the tunnel deformation pattern classifier can be constructed in the following manner: for a multi-layer tunnel twin model, sample superimposed offset information is collected separately to obtain multiple sample superimposed tunnel offset information sets, and multiple sample tunnel deformation patterns corresponding to the multiple sample superimposed tunnel offset information are obtained to form multiple sample tunnel deformation pattern sets. Furthermore, the multiple sample superimposed tunnel offset information sets and the multiple sample tunnel deformation pattern sets are used as training data, combined with a fully connected neural network, to construct and train multiple tunnel deformation pattern classification branches, and the multiple tunnel deformation pattern classification branches are merged to obtain a tunnel deformation pattern classifier.

[0057] Furthermore, the multiple superimposed tunnel offset information is input into a tunnel deformation pattern classifier for classification to obtain multiple tunnel deformation patterns, the types of the multiple tunnel deformation patterns are counted, and the tunnel deformation pattern with the largest number of occurrences, that is, the largest proportion, is output as the construction monitoring result, and then targeted measures are taken according to the construction monitoring results to carry out tunnel safety processing.

[0058] In summary, the embodiments of the present application have at least the following technical effects:

[0059] The present application collects multiple construction information superimposed in parallel construction, performs stress field analysis respectively, obtains multiple stress field information, constructs a tunnel twin model, and divides a multi-layer tunnel twin sub-model to perform stress field division and tunnel offset information analysis to obtain multiple tunnel offset information sets. The tunnel construction deformation analysis is performed based on multiple superimposed tunnel offset information, and the tunnel deformation mode with the largest proportion is output as the construction monitoring result.
