[0037] In the process of conceiving this invention, the inventors discovered that the deformation monitoring technology for the interior of the foundation pit soil in related technologies is easily affected by external environmental factors such as rainfall, corrosion and construction disturbance, resulting in low survival rate of monitoring equipment, poor durability, high monitoring cost, and low accuracy of monitoring results. The integration level of monitoring systems of different types of monitoring equipment is not high, and the monitoring of internal soil deformation is easily limited by the sampling frequency, all of which lead to low monitoring efficiency, inability to timely warn of potential deformation risks, and easy to miss the best support time, making it difficult to guarantee the economy and safety of foundation pit projects.

[0038] In view of this, the present invention can directly determine the deformation data of the foundation pit wall based on the horizontal displacement data of the wall. Then, the horizontal and vertical strain data of the soil can be determined by using the rotation data, translation data and hinge data in the deformation data. Based on the horizontal and vertical strain data, the soil deformation data of the foundation pit can be obtained.

[0047] It should be understood that Figure 1 The number of terminal devices, networks, monitoring devices, and servers shown is merely illustrative. Depending on implementation needs, any number of terminal devices, monitoring devices, networks, and servers can be included.

[0048] Figure 2 A flowchart of a method for determining soil deformation in a foundation pit according to an embodiment of the present invention is shown.

[0049] like Figure 2 As shown, the method for determining the deformation of the foundation pit soil in this embodiment includes operations S210 to S240.

[0050] In operation S210, based on the horizontal displacement data of the foundation pit wall, the deformation data corresponding to the wall is determined. The deformation data includes rotation data, translation data, and hinge data.

[0051] According to embodiments of the present invention, horizontal displacement data can characterize the horizontal displacement of the foundation pit wall (retaining wall) caused by external forces. Deformation data can be categorized into rotational data, translational data, and hinge data based on different types of wall deformation. It is understood that in engineering monitoring, when the retaining wall is subjected to external soil pressure, a preset range of wall deformation is permissible.

[0052] In embodiments of the present invention, the wall can be considered a rigid body. Rotation data can characterize the deformation data generated when the bottom of the wall is fixed and other parts of the wall rotate clockwise or counterclockwise along the bottom. Translation data can characterize the horizontal movement of the wall in different directions when the wall is considered a rigid body. Hinge data can characterize the deformation data generated when the top and bottom of the wall are used as pin-connected members and other wall parts (including the upper and lower sides) are used as two straight line segments for deflection.

[0053] It is understandable that hinge data can be viewed as deformation data generated by the rotational deformation produced by multiple hinge mechanisms. This hinge mechanism can be equivalent to superimposed wall rotation mechanisms in two different directions: the lower segment is pinned at the bottom and rotates around the bottom, while the upper segment rotates in the opposite direction around the hinge. The superposition of the two wall rotation mechanisms in different directions fixes the top of the wall.

[0054] In operation S220, soil strain data is determined using rotation data, translation data, and hinge data, which includes horizontal strain data and vertical strain data.

[0055] According to embodiments of the present invention, soil strain data can characterize the strain data of the foundation pit soil in multiple directions corresponding to the process of rotational deformation, translational deformation, or hinge deformation of the wall. Horizontal strain data may include horizontal strain data corresponding to the rotational deformation, translational deformation, and hinge deformation of the wall, which can be respectively denoted as first horizontal strain data, second horizontal strain data, and third horizontal strain data; vertical strain data may include vertical strain data corresponding to the rotational deformation, translational deformation, and hinge deformation of the wall, which can be respectively denoted as first vertical strain data, second vertical strain data, and third vertical strain data.

[0056] In operation S230, the horizontal strain data and vertical strain data are mapped to their respective initial matrices to obtain the horizontal strain increment matrix and the vertical strain increment matrix.

[0057] According to an embodiment of the present invention, the initial matrix can characterize the deformation matrix of the soil inside the foundation pit before excavation, and can be set as an n-order all-zero square matrix. The strain increment matrix can characterize the change (increment) between the strain data of the foundation pit soil in its original state and the strain data of the soil in its construction state. After obtaining the horizontal strain data and the vertical strain data, the first horizontal strain data, the second horizontal strain data, the third horizontal strain data, the first vertical strain data, the second vertical strain data, and the third vertical strain data can be mapped to the initial matrix in the corresponding direction, respectively, to obtain the horizontal strain increment matrix and the vertical strain increment matrix of the soil.

[0058] According to an embodiment of the present invention, after mapping the first horizontal strain data, the second horizontal strain data, and the third horizontal strain data to an initial matrix, a rotational horizontal strain increment matrix, a translational horizontal strain increment matrix, and a hinge horizontal strain increment matrix can be obtained, respectively. After mapping the first vertical strain data, the second vertical strain data, and the third vertical strain data to the initial matrix, a first vertical strain increment matrix (rotational vertical strain increment matrix), a second vertical strain increment matrix (translational vertical strain increment matrix), and a third vertical strain increment matrix (hinge vertical strain increment matrix) can be obtained, respectively.

[0059] In operation S240, the soil deformation vector data is determined based on the horizontal strain increment matrix and the vertical strain increment matrix, and the soil deformation results of the foundation pit are obtained.

[0060] According to an embodiment of the present invention, after determining the horizontal strain increment matrix and the vertical strain increment matrix, the horizontal strain increment matrix and the vertical strain increment matrix can be superimposed and mapped to the initial soil mesh to obtain soil deformation vector data. The initial soil mesh is the initial mesh corresponding to the initial matrix.

[0061] According to embodiments of the present invention, soil strain data may include horizontal strain data and vertical strain data. The horizontal strain data may include first horizontal strain data (rotational horizontal strain data), second horizontal strain data (translational horizontal strain data), and third horizontal strain data (hinge horizontal strain data). The vertical strain data may include first vertical strain data (rotational vertical strain data), second vertical strain data (translational vertical strain data), and third vertical strain data (hinge vertical strain data).

[0062] In one feasible embodiment, the rotational horizontal strain data can characterize the increment of soil horizontal strain corresponding to the rigid rotation of the wall around its base, and can be denoted as... Rotational vertical strain data can characterize the increase in vertical strain of the soil corresponding to the rigid rotation of the wall around its base, and can be denoted as... ,in, The angular increment representing the rigid rotation of the wall around its base, in radians, where r represents the rigid rotation of the wall around its base, h represents the horizontal change, and v represents the vertical change; the translational horizontal strain data can characterize the increment of the soil's horizontal strain corresponding to the rigid translation of the wall, and can be denoted as... Translational vertical strain data can characterize the increase in vertical strain of the soil corresponding to the rigid translation of the wall, and can be denoted as... ,in, Let t represent the rigid translation of the wall, and l represent the length of the wall. The hinge horizontal strain data can include the superposition of two different wall rotation mechanisms. The horizontal strain increment of the soil corresponding to the upper line segment can be denoted as... The vertical strain increment of the soil corresponding to the upper line segment can be denoted as... ,in, , Let be the included angle of the i-th hinge component, in radians. The upper side line strain increment is generally marked with a "-" sign to indicate reverse rotation; the soil horizontal strain increment corresponding to the lower side line segment can be denoted as . The vertical strain increment of the soil corresponding to the lower line segment can be denoted as... ,in, X can represent the vertical distance from the top of the wall to the i-th hinge.

[0063] According to embodiments of the present invention, the deformation data of the foundation pit wall can be directly determined based on the horizontal displacement data of the foundation pit wall. Then, the horizontal and vertical strain data of the soil can be determined using the rotational, translational, and hinge data within the deformation data. Furthermore, the soil deformation data of the foundation pit can be obtained based on the horizontal and vertical strain data. Since the soil deformation results of the foundation pit can be obtained simply by processing the deformation data of the foundation pit wall, the drawbacks of traditional techniques—such as the difficulty, low efficiency, and low accuracy of obtaining deformation data through internal soil monitoring—are avoided. This allows for real-time and efficient monitoring of the soil deformation in the foundation pit, further improving the safety and economy of foundation pit engineering.

[0064] As you can understand, the above text has provided an example of how to determine the deformation results of the foundation pit soil. The following text will further explain how to determine the soil deformation vector data.

[0065] According to an embodiment of the present invention, determining soil deformation vector data based on a horizontal strain increment matrix and a vertical strain increment matrix includes: processing the horizontal strain increment matrix and the vertical strain increment matrix to obtain soil deformation data; and determining soil deformation vector data based on the soil deformation data.

[0066] According to embodiments of the present invention, the method of obtaining soil deformation data by superimposing and mapping the horizontal strain increment matrix and the vertical strain increment matrix may include: horizontally superimposing the product of the elements of the horizontal strain increment matrix of the soil with the length of a single grid in the initial matrix to obtain the horizontal deformation vector data of the soil; vertically accumulating the product of the elements of the vertical strain increment matrix of the soil with the length of a single grid in the initial matrix to obtain the vertical deformation vector data of the soil; and then obtaining the soil deformation result of the foundation pit based on the horizontal deformation vector data and the vertical deformation vector data of the soil.

[0067] According to embodiments of the present invention, soil deformation data can be obtained by superimposing the horizontal strain increment matrix and the vertical strain increment matrix and mapping them to soil mesh data. The soil deformation data can include horizontal soil deformation data and vertical soil deformation data. The soil mesh data can represent an initial n×n mesh, where the length of a single mesh can be l / n-1, where l is the length of the wall. The methods for obtaining soil deformation data can include: horizontally accumulating the product of the elements of the horizontal strain increment matrix and the length of a single mesh to obtain horizontal soil deformation data; and vertically accumulating the product of the elements of the vertical strain increment matrix and the length of a single mesh to obtain vertical soil deformation data.

[0068] As you can understand, the above text has provided an example of how to determine soil deformation vector data. The following text will provide a further explanation of how to determine soil deformation vector data.

[0069] According to an embodiment of the present invention, determining soil deformation vector data based on a horizontal strain increment matrix and a vertical strain increment matrix includes: superimposing the horizontal strain increment matrix and the vertical strain increment matrix respectively to obtain a target horizontal matrix and a target vertical matrix; mapping the target horizontal matrix and the target vertical matrix to soil grid data respectively to generate soil horizontal deformation data and soil vertical deformation data; and determining soil deformation vector data based on the soil horizontal deformation data and soil vertical deformation data.

[0070] According to an embodiment of the present invention, after determining the rotational horizontal strain increment matrix, the translational horizontal strain increment matrix, and the hinge horizontal strain increment matrix, the rotational horizontal strain increment matrix, the translational horizontal strain increment matrix, and the hinge horizontal strain increment matrix can be superimposed to obtain the target horizontal matrix. At the same time, the first vertical strain increment matrix, the second vertical strain increment matrix, and the third vertical strain increment matrix can be superimposed to obtain the target vertical matrix. Then, the target horizontal matrix and the target vertical matrix can be mapped to soil mesh data respectively to obtain soil horizontal deformation data and soil vertical deformation data.

[0071] In embodiments of the present invention, soil deformation vector data can also be referred to as soil deformation vector field. The soil deformation vector field characterizes the displacement of each point in the soil, with each point's displacement consisting of two components: horizontal displacement and vertical displacement. The soil deformation vector field can be obtained by superimposing the horizontal and vertical deformation data of the soil. For example, determining the horizontal displacement m1 and vertical displacement m2 of the soil can be represented by vectors or matrices; adding m1 and m2 yields the soil deformation vector field M.

[0072] According to embodiments of the present invention, by analyzing deformation data (deformation field), potential deformation risk areas can be identified, thereby optimizing the design of the foundation pit support structure and improving its stability and safety. At the same time, by determining the soil deformation vector data (vector field), the deformation direction and amplitude of the soil can be visually observed, helping to assess the impact of foundation pit excavation on the surrounding environment. By analyzing the evolution of the deformation field, a reasonable monitoring plan can be formulated, abnormal deformation can be detected in a timely manner, and measures can be taken to prevent further displacement of the foundation pit soil. This allows for a better assessment of the impact of foundation pit construction on surrounding buildings, infrastructure, and underground pipelines, thereby enabling the formulation of corresponding risk management measures to reduce construction risks and economic losses.

[0073] As you can understand, the above text has provided an example of how to determine soil deformation vector data. The following text will explain how to determine the horizontal strain increment matrix and the vertical strain increment matrix.

[0074] According to an embodiment of the present invention, the horizontal strain increment matrix includes a rotational horizontal strain increment matrix, a translational horizontal strain increment matrix, and a hinge horizontal strain increment matrix; the vertical strain increment matrix includes a rotational vertical strain increment matrix, a translational vertical strain increment matrix, and a hinge vertical strain increment matrix. Mapping the horizontal strain data and vertical strain data to their respective initial matrices to obtain the horizontal strain increment matrix and vertical strain increment matrix includes: mapping the horizontal strain data to the initial matrices to obtain the rotational horizontal strain increment matrix, the translational horizontal strain increment matrix, and the hinge horizontal strain increment matrix; and mapping the vertical strain data to the initial matrices to obtain the rotational vertical strain increment matrix, the translational vertical strain increment matrix, and the hinge vertical strain increment matrix. The horizontal strain increment matrix and vertical strain increment matrix include their respective element data and mesh length data. The element data includes rotational element data, translational element data, and hinge element data, and the hinge element data includes multiple hinge element sub-data.

[0075] According to an embodiment of the present invention, before the excavation of the foundation pit, the initial soil deformation matrix can be preset as an n-order all-zero square matrix. n can be determined according to actual needs, satisfying n > 1 and n is a positive integer, for example, n = 50. After defining the initial matrix and obtaining the horizontal and vertical strain data, the horizontal and vertical strain data can be mapped to the initial matrix respectively, thereby obtaining the rotational horizontal strain increment matrix, the translational horizontal strain increment matrix and the hinge horizontal increment matrix, as well as the rotational vertical strain increment matrix, the translational vertical strain increment matrix and the hinge vertical increment matrix.

[0076] In one feasible embodiment, the rotational horizontal strain increment matrix and the rotational vertical strain increment matrix can be strictly upper triangular matrices of order n; the translational horizontal strain increment matrix and the translational vertical strain increment matrix can be square matrices of order n; in the hinge strain increment matrix, the hinge horizontal increment matrix and the hinge vertical increment matrix corresponding to the deformation of the lower segment of the i-th hinge mechanism can be strictly upper triangular matrices of order n, and the hinge horizontal increment matrix and the hinge vertical increment matrix corresponding to the deformation of the upper segment can be upper triangular matrices of order n containing diagonal offset terms ki.

[0077] According to embodiments of the present invention, the horizontal and vertical strain increments are systematically expressed in matrix form, enabling systematic strain analysis, facilitating overall analysis and processing, and enhancing the readability and operability of the model. The matrix method simplifies the calculation process, enabling convenient numerical simulation, especially in large-scale soil data analysis, effectively improving computational efficiency. Integrating strain data from different directions into a unified matrix enhances data integration capabilities, facilitating multi-dimensional data analysis and comparison, and improving information usability.

Translational strain data can be determined by superimposing the horizontal and vertical strain data corresponding to the translational data. Hinge strain data can be obtained by superimposing the horizontal and vertical strain data corresponding to the hinge data. Rotational strain data, translational strain data, and hinge strain data are important factors in analyzing the stability and bearing capacity of soil, affecting the safety and economy of foundation pit construction.

[0085] As we have already explained above, this section provides examples of how to determine rotational strain data, translational strain data, and hinge strain data. The following section will further explain how to determine the horizontal strain increment matrix and the vertical strain increment matrix.

[0086] According to an embodiment of the present invention, the horizontal strain increment matrix includes a rotational horizontal strain increment matrix, a translational horizontal strain increment matrix, and a hinge horizontal strain increment matrix, and the vertical strain increment matrix includes a rotational vertical strain increment matrix, a translational vertical strain increment matrix, and a hinge vertical strain increment matrix.

The matrix element values ​​of the hinge horizontal increment matrix and the hinge vertical increment matrix of the multiple hinge components can be respectively... and , where N is the total number of multiple hinge components.

[0090] According to an embodiment of the present invention, after determining the rotational horizontal strain increment matrix, the rotational vertical strain increment matrix, the translational horizontal strain increment matrix, the translational vertical strain increment matrix, the hinge horizontal increment matrix, and the hinge vertical increment matrix, the element values ​​of the total horizontal strain increment matrix and the vertical strain increment matrix of the foundation pit soil can be determined as follows: and .

[0091] As you can understand, the above text has provided an example of how to determine the horizontal strain increment matrix and the vertical strain increment matrix. The following text will further explain how to determine the horizontal strain data and the vertical strain data.

[0092] According to an embodiment of the present invention, soil strain data is determined using rotational data, translational data, and hinge data, including: determining a deformation strategy corresponding to each of the rotational data, translational data, and hinge data; and determining horizontal strain data and vertical strain data based on the deformation strategy, rotational data, translational data, and hinge data.

[0093] According to an embodiment of the present invention, after determining the wall deformation data, the wall deformation data can be decomposed into rigid wall rotation data around the bottom (rotation data), rigid wall translation data (translation data), and deformation data of multiple hinge mechanisms (hinge data). The rigid wall rotation data around the bottom characterizes the data corresponding to clockwise or counterclockwise rotation with the wall considered a rigid body and its bottom fixed. The rigid wall translation data characterizes the data corresponding to horizontal left or right movement with the wall considered a rigid body. The deformation data of multiple hinge mechanisms characterizes the wall top and bottom being pinned together, with the wall deflected as two straight segments connected by hinges. This is equivalent to superimposing two different wall rotation mechanisms: the lower segment is pinned at the bottom and rotates around the bottom, while the upper segment rotates in the opposite direction around the hinge. The superposition of these two different wall rotation mechanisms fixes the top of the wall. After determining the rotation data, translation data, and hinge data, the corresponding horizontal strain increment and vertical strain increment of the soil can be calculated based on the rotation, translation, and hinge deformation strategies, respectively.

[0094] In one feasible embodiment, the prediction of soil deformation results is illustrated by taking the horizontal displacement of the wall measured by a measuring plane in the open-cut deep foundation pit at the end of Port A tunnel. The basic information of the foundation pit and the support load information are shown in Table 1. Table 1 shows the basic information of the foundation pit and the support load information according to the embodiment of the present invention.

Figure 4 Table 2 further illustrates the wall horizontal displacement, hinge mechanism, rotation angle data, and strain increment matrix of the present invention.

[0099] Figure 4 A schematic diagram of the measured horizontal displacement of a wall according to an embodiment of the present invention is shown.

[0100] like Figure 4 As shown, the inclinometer did not extend to the bottom of the retaining wall, but terminated at a depth of 18 meters, resulting in a lack of certainty regarding lateral displacement data. When plotting the field data, it was assumed that the lateral displacement from the 18-meter depth to the bottom of the retaining wall was zero. This assumption is reasonable in the absence of contradictory data. Meanwhile, the horizontal displacement value at the top of the wall was missing. Multinomial regression was used to fit the measured horizontal displacement of the wall. A total of 49 measuring points were fitted, of which 38 points were measured values, the horizontal displacement at the top of the wall was the fitted value (0.430 mm), and the horizontal displacement at the remaining measuring points was 0.

[0101] Based on the information from each measuring point, the wall deformation can be decomposed into rotational data, translational data, and hinge data. Among these, the rotational data includes the angular increment. for displacement increment of translation data The value is 0. The wall deformation is decomposed into 47 hinge mechanisms sequentially downwards from the top of the wall, as detailed in Table 2. Table 2 shows the hinge mechanisms and rotation data according to an embodiment of the present invention.

[0104] Based on the increment of horizontal soil strain corresponding to the rigid rotation of the wall around its base The obtained soil horizontal strain increment matrix (square matrix) and soil vertical strain increment The obtained vertical strain increment matrices (square matrices) of the soil are as follows:

[0105]

[0106] Due to the displacement increment of rigid translation of the wall The value is 0, representing the increase in horizontal soil strain corresponding to the rigid translation of the wall. The obtained soil horizontal strain increment matrix and soil vertical strain increment The obtained vertical strain increment matrices of the soil are all zero matrices (square matrices) with n=50.

[0107] In an embodiment of the present invention, the soil horizontal and vertical strain increment matrices corresponding to the deformation of multiple hinge mechanisms can be the superposition of the soil horizontal and vertical strain increment matrices corresponding to 47 hinge mechanisms respectively. Here, the hinge mechanism is used as an example. ( Taking the calculation of the horizontal and vertical strain increment matrices of soil as an example: it can be seen that... as well as The horizontal strain increment of the soil corresponding to the lower line segment The vertical strain increment of the soil corresponding to the lower line segment The increment of horizontal strain in the soil corresponding to the upper line segment The vertical strain increment of the soil corresponding to the upper line segment diagonal offset term Therefore, the increment of horizontal soil strain corresponding to the third hinge mechanism. The obtained soil horizontal strain increment matrix (square matrix) and soil vertical strain increment The obtained vertical strain increment matrices (square matrices) of the soil are as follows:

[0108] and

[0109] In embodiments of the present invention, the calculation methods for the soil horizontal strain increment matrix and soil vertical strain increment matrix corresponding to the deformation of the remaining hinge mechanisms can be the same as described above. After obtaining the soil horizontal strain increment matrix and vertical strain increment matrix, the soil horizontal strain increment matrix and vertical strain increment matrix of the deformation mechanisms of rigid wall rotation around the bottom, rigid wall translation, and multiple hinge mechanisms can be superimposed respectively, mapped to the initial soil mesh, and the soil horizontal deformation data and soil vertical deformation data can be obtained.

[0112] In this embodiment of the invention, the initial soil mesh can represent a 50×50 initial mesh, with a single mesh length of [missing information]. .like Figure 5 As shown in Figure (a), the horizontal deformation data of the soil can be obtained by multiplying the elements of the horizontal strain increment matrix of the soil by the length of a single grid; as shown in Figure (a). Figure 5 As shown in Figure (b), the vertical deformation data of the soil can be obtained by multiplying the elements of the vertical strain increment matrix of the soil vertically with the length of a single grid. Figure 5 As shown in Figure (c), the soil deformation vector field can be obtained by superimposing the soil horizontal deformation data and the soil vertical deformation data.

The deformation data 620 can include rotation data 621, translation data 622, and hinge data 623. Using the rotation data 621, translation data 622, and hinge data 623, the soil strain data 630 can be determined. The soil strain data 630 can include horizontal strain data 631 and vertical strain data 632. Thus, the horizontal strain data 631 and vertical strain data 632 are mapped to their respective initial matrices 640 to obtain the strain. The incremental matrix 650 includes a horizontal strain increment matrix 651 and a vertical strain increment matrix 652. The horizontal strain increment matrix 651 and the vertical strain increment matrix 652 are then superimposed and mapped to obtain soil deformation data 660. Soil deformation data 660 can include horizontal soil deformation data 661 and vertical soil deformation data 662. The horizontal soil deformation data 661 and the vertical soil deformation data 662 are then superimposed to obtain soil deformation vector data 670.
