Description

Technical Field

[0001] This invention belongs to the field of settlement monitoring technology for support structures, and more specifically, relates to an intelligent monitoring method and system for settlement of deep foundation pit support structures. Background Technology

[0002] Existing settlement control technologies for deep foundation pit support structures mainly rely on the following three types of methods: First, finite element analysis (FEA), which predicts the structural response by establishing a mechanical model containing physical parameters (such as elastic modulus and Poisson's ratio). However, this method is highly sensitive to soil and support structure parameters, which are difficult to obtain accurately on-site, and the model iteration is complex. Second, monitoring combined with threshold early warning method, which provides early warning by setting settlement monitoring points and setting fixed alarm values ​​(such as ±10mm). However, it cannot identify trend changes and often results in response lag. Third, data-driven prediction methods (such as machine learning), which fit prediction models through historical data. However, they lack engineering semantics and physical interpretability, making them difficult to use for control decisions.

[0003] Therefore, a technical solution is urgently needed to solve the above technical problems. Summary of the Invention

[0004] To address the above technical problems, this invention proposes an intelligent monitoring method for settlement of deep foundation pit support structures, comprising:

[0005] Extract engineering elements and convert them into discrete engineering state symbol groups. Construct a structural mapping container in finite element analysis based on the engineering state symbol groups.

[0006] The settlement value of the deep foundation pit support structure is acquired in real time and converted into the first current dimensionless symbol, which is then used as the response trigger signal for finite element analysis and input into the structure mapping container.

[0007] Obtain the mapping relationship between the engineering state symbol group corresponding to the first current dimensionless symbol and the second current dimensionless symbol group, and use it as the boundary behavior of finite element analysis. The second current dimensionless symbol group consists of historical dimensionless symbols and future dimensionless symbols.

[0008] Determine whether the boundary behavior of the finite element analysis is abnormal. If it is abnormal, generate construction suggestions and carry out construction according to the construction suggestions.

[0009] Furthermore, the engineering state symbol group consists of: support type, soil permeability, and environmental boundary, forming a ternary group as the engineering state symbol group.

[0010] Furthermore, the real-time acquisition of settlement values ​​of deep foundation pit support structures and their conversion into the first dimensionless symbol includes:

[0011] The settlement values ​​of the deep foundation pit support structure acquired in real time are normalized to eliminate dimensions, specifically as follows:

[0012] ,

[0013] in, For time Timing in the support structure Normalized settlement value For time Point at support structure Settlement value at the location, In the support structure The historical average settlement value at the location, The standard deviation of historical settlement.

[0014] Furthermore, time At the time of support structure Normalized settlement values The conversion to the first current dimensionless symbol includes:

[0015] ,

[0016] in, For time Point at support structure The first dimensionless symbol at the current position, The first threshold, The second threshold, This is the third threshold.

[0017] Furthermore, obtaining the mapping relationship between the engineering state symbol group corresponding to the first current dimensionless symbol and the second current dimensionless symbol group includes:

[0018] By querying preset mapping rules, the engineering state symbol group corresponding to the first current dimensionless symbol is mapped to the second current dimensionless symbol group, or a lightweight classification model is trained based on the correspondence between historical engineering state symbol groups and the second current dimensionless symbol group, thereby mapping the engineering state symbol group to the second current dimensionless symbol group.

[0019] Furthermore, determining whether the boundary behavior of the finite element analysis is abnormal includes: if the first current dimensionless symbol is greater than the future dimensionless symbol in the second current dimensionless symbol group, then the first current dimensionless symbol replaces the future dimensionless symbol to form a new dimensionless symbol group, and the dimensionless symbols of multiple time points before and after the corresponding time point of the first current dimensionless symbol are obtained.

[0020] If the first current dimensionless symbol is equal to the future dimensionless symbol in the second current dimensionless symbol group, then obtain the dimensionless symbols of multiple time points before and after the time point corresponding to the first current dimensionless symbol.

[0021] If the first current dimensionless symbol is smaller than the future dimensionless symbol in the second current dimensionless symbol group, then the boundary behavior of the finite element analysis is abnormal, and a construction suggestion operation is generated.

[0022] Furthermore, if the first current dimensionless symbol is greater than the future dimensionless symbol in the second current dimensionless symbol group, or if the first current dimensionless symbol is equal to the future dimensionless symbol in the second current dimensionless symbol group, then a feedback judgment gating function is used to determine whether to generate a construction suggestion operation. The feedback judgment gating function is:

[0023] ,

[0024] in, For time Point-to-point gating value, For time Point at support structure The change in the first dimensionless symbol at the current position. For time Point at support structure The change in the dimensionless sign at the location;

[0025] When time Point-to-point gating value When the value is 1, a construction suggestion operation is generated, and construction is carried out according to the construction suggestion operation.

[0026] This invention also proposes an intelligent monitoring system for settlement of deep foundation pit support structures, comprising:

[0027] The module for obtaining engineering state symbol groups is used to extract engineering elements, convert them into discrete engineering state symbol groups, and construct a structural mapping container in finite element analysis based on the engineering state symbol groups.

[0028] The module for acquiring response trigger signals is used to acquire the settlement value of the deep foundation pit support structure in real time and convert it into the first current dimensionless symbol, and input it into the structure mapping container as the response trigger signal for finite element analysis.

[0029] The boundary behavior module is set to obtain the mapping relationship between the engineering state symbol group corresponding to the first current dimensionless symbol and the second current dimensionless symbol group, and to serve as the boundary behavior for finite element analysis. The second current dimensionless symbol group consists of historical dimensionless symbols and future dimensionless symbols.

[0030] The judgment module is used to determine whether the boundary behavior of the finite element analysis is abnormal. If it is abnormal, it generates construction suggestion operations and performs construction according to the construction suggestion operations.

[0031] Furthermore, the engineering state symbol group consists of: support type, soil permeability, and environmental boundary, forming a ternary group as the engineering state symbol group.

[0032] Furthermore, the real-time acquisition of settlement values ​​of deep foundation pit support structures and their conversion into the first dimensionless symbol includes:

[0033] The settlement values ​​of the deep foundation pit support structure acquired in real time are normalized to eliminate dimensions, specifically as follows:

[0034] ,

[0035] in, For time Timing in the support structure Normalized settlement value For time Point at support structure Settlement value at the location, In the support structure The historical average settlement value at the location, The standard deviation of historical settlement.

[0036] In summary, the technical solutions conceived by this invention have the following beneficial effects compared with the prior art:

[0037] First, the initial engineering conditions are transformed into structural "behavioral labels" using engineering state symbol groups, avoiding dependence on mechanical parameters. Then, dimensionless symbols standardize real-time monitoring data into a settlement trend symbol stream, enhancing the model's ability to perceive local anomalies. Next, the symbol trends are mapped to the boundary adjustment instructions of the finite element model through the mapping relationship between the engineering state symbol group and the second current dimensionless symbol group, realizing data-driven structural evolution simulation. Finally, it is determined whether the boundary behavior of the finite element analysis is abnormal, thereby determining whether feedback adjustment is needed, forming an evolutionary closed loop.

[0046] Example 1

[0047] like Figure 1 As shown in the figure, this embodiment proposes an intelligent monitoring method for the settlement of deep foundation pit support structures, including:

[0048] Step 101: Extract engineering elements and convert them into discrete engineering state symbol groups. Construct a structural mapping container in finite element analysis based on the engineering state symbol groups.

[0049] Preferably, this embodiment is based on the original geological parameters, structural design drawings, and support layout scheme, and extracts engineering elements.

[0050] Specifically, the engineering state symbol group consists of: support type, soil permeability and environmental boundary, forming a ternary group as the engineering state symbol group.

[0051] Regarding the aforementioned engineering status symbol group, this embodiment provides the following examples for illustration:

[0052] Support method: ,in, These represent diaphragm wall, support, and anchor cable, respectively.

[0053] Soil permeability: ,in, These represent high, medium, and low permeability, respectively.

[0054] Environmental boundary: ,in, These represent nearby buildings, intersections, and traffic loads, respectively.

[0055] For example, the engineering status symbol group This refers to a diaphragm wall located near an existing building in a highly permeable stratum.

[0056] Step 102: Real-time acquisition of the settlement value of the deep foundation pit support structure and conversion into the first current dimensionless symbol, which is then used as the response trigger signal for finite element analysis and input into the structure mapping container.

[0057] Specifically, real-time acquisition of settlement values ​​of deep foundation pit support structures and conversion into the first dimensionless symbol includes:

[0058] The settlement values ​​of the deep foundation pit support structure acquired in real time are normalized to eliminate dimensions, specifically as follows:

[0059] ,

[0062] ,

[0063] in, For time Point at support structure The first dimensionless symbol at the current position, The first threshold, The second threshold, This is the third threshold.

[0064] In order to To make the meaning clearer, the following example is provided in this embodiment for explanation:

[0065] ,

[0066] Step 103: Obtain the mapping relationship between the engineering state symbol group corresponding to the first current dimensionless symbol and the second current dimensionless symbol group, and use it as the boundary behavior of the finite element analysis. The second current dimensionless symbol group consists of historical dimensionless symbols and future dimensionless symbols.

[0067] Specifically, obtaining the mapping relationship between the engineering state symbol group corresponding to the first current dimensionless symbol and the second current dimensionless symbol group includes:

[0068] By querying preset mapping rules, the engineering state symbol group corresponding to the first current dimensionless symbol is mapped to the second current dimensionless symbol group, or a lightweight classification model (such as decision tree, SVM, Transformer) is trained based on the correspondence between historical engineering state symbol groups and the second current dimensionless symbol group, thereby mapping the engineering state symbol group to the second current dimensionless symbol group.

[0069] For example, by querying the mapping rule table (as shown in the table below), the engineering status symbol group corresponding to the first current dimensionless symbol can be mapped to the second current dimensionless symbol group:

[0070] , Step 104: Determine whether the boundary behavior of the finite element analysis is abnormal. If it is abnormal, generate construction suggestion operations and carry out construction according to the construction suggestion operations.

[0071] Preferably, the recommended construction operations can be: sealing the bottom in advance, adding internal supports, and stopping excavation for 1 day. This embodiment does not limit the recommended construction operations, and users can adjust them according to their actual needs.

[0072] Specifically, determining whether the boundary behavior of the finite element analysis is abnormal includes: if the first current dimensionless symbol is greater than the future dimensionless symbol in the second current dimensionless symbol group (which can be understood as the second current dimensionless symbol group predicted based on the engineering state symbol group), then the first current dimensionless symbol replaces the future dimensionless symbol to form a new dimensionless symbol group, and the dimensionless symbols of multiple time points before and after the corresponding time point of the first current dimensionless symbol are obtained;

[0073] If the first current dimensionless symbol is equal to the future dimensionless symbol in the second current dimensionless symbol group, then obtain the dimensionless symbols of multiple time points before and after the time point corresponding to the first current dimensionless symbol.

[0074] If the first current dimensionless symbol is smaller than the future dimensionless symbol in the second current dimensionless symbol group, then the boundary behavior of the finite element analysis is abnormal, and a construction suggestion operation is generated.

[0075] Preferably, this embodiment illustrates step 104 through an example, as shown below:

[0076] If the first dimensionless symbol is currently =2, the second current dimensionless symbol group is {1,2}, if the first current dimensionless symbol =2 is a newly appearing symbol (changing from 1 to 2), indicating that the system is evolving as expected; if the first current dimensionless symbol... =3 indicates that the system may be out of control, the rules are invalid, and an alarm should be triggered.

[0077] If the first dimensionless symbol is currently =2, and the second current dimensionless symbol group is {2,3}, then notify the construction unit in advance: please strengthen the support or adjust the excavation rhythm.

[0078] Specifically, if the first current dimensionless symbol is greater than the future dimensionless symbol in the second current dimensionless symbol group, or if the first current dimensionless symbol is equal to the future dimensionless symbol in the second current dimensionless symbol group, then a feedback judgment gating function is used to determine whether to generate a construction suggestion operation. The feedback judgment gating function is:

[0079] ,

[0080] in, For time Point-to-point gating value, For time Point at support structure The change in the first dimensionless symbol at the current position. For time Point at support structure The change in the dimensionless sign at the location;

[0081] When time Point-to-point gating value When the value is 1, a construction suggestion operation is generated, and construction is carried out according to the construction suggestion operation.
