Abstract
Description
Technical Field
[0001] This application relates to the field of construction engineering, and in particular to a method, device, equipment and storage medium for predicting the risk of pipe pile deviation. Background Technology
[0002] With the advancement of urbanization, the demand for underground space development is increasing, leading to a continuous increase in the excavation depth of foundation pit projects (such as underground parking garages, underground shopping malls, and subway station supporting foundation pits), and making the construction environment increasingly complex. Pipe pile foundations are a common type of foundation. When a deep silt layer exists at the construction site, the silt layer, due to its high water content, high compressibility, low strength, and high fluidity, makes it difficult to provide an effective working surface for pipe pile construction. In some projects, pipe piles are constructed on the original ground surface before foundation pit excavation. However, when excavating foundation pits in deep silt layers, the silt layer is disturbed by construction machinery during the excavation process, causing drastic changes in the soil stress state. The completed pipe piles are then subjected to uneven lateral earth pressure from the surrounding silt layer. This complex stress state can easily cause the pipe pile to tilt or deviate (i.e., "pile deviation"). Pipe deviation not only significantly reduces the vertical bearing capacity and pull-out resistance of the pipe pile, but may also trigger a chain of risks such as pipe pile fracture and instability of the foundation pit support structure. In severe cases, it may even lead to project delays and rework, causing huge economic losses and posing a potential threat to the life safety of construction workers.
[0003] Currently, the engineering community's approach to addressing the issue of pile deviation in deep silt layers largely relies on construction experience or post-construction remediation. For example, deviation is detected after excavation, followed by corrective measures or additional piles. However, this "post-construction" approach cannot anticipate the risk of pile deviation in advance, making it difficult to fundamentally avoid the engineering hazards it poses. Furthermore, existing technologies lack quantitative analysis methods that combine site geological conditions with the actual construction of the piles, resulting in a lack of scientific rigor and accuracy in assessing pile deviation risk. This fails to provide a reliable basis for optimizing excavation plans and developing pile protection measures. Therefore, a method for analyzing the risk of pile deviation in silt layers is urgently needed. Summary of the Invention

[0043] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0044] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.
[0045] The following description, in conjunction with the accompanying drawings, provides an exemplary description of the pipe pile deviation risk prediction method, apparatus, equipment, and storage medium provided in the embodiments of this application. Figure 1 This is a flowchart illustrating the method for predicting pile deviation risk in an embodiment of this application.

Figure 3 This is a schematic diagram of the structure of the first triangular mesh provided in an embodiment of this application.

Figure 5 This is a schematic diagram of the structure of the triangular mesh model provided in the embodiments of this application. Figure 6 This is a structural schematic diagram illustrating the spatial relationship between the pipe pile and the silt layer, provided as an embodiment of this application. Figure 7 This is a schematic diagram illustrating the predicted risk of pile deviation for each of the pipe piles described in the embodiments of this application. First, refer to... Figure 1 The method 100 for predicting the risk of pile deviation includes the following steps:
[0046] S101. Obtain geological survey data and construction data of the pipe piles at the target site. The geological survey data includes exploration boreholes, foundation pit boundary control points, and foundation pit bottom excavation depth.
[0047] Specifically, it involves obtaining geological survey data and construction data of the pipe piles at the target site, which form the basis for subsequent analysis and risk assessment. Figure 2 This is a schematic diagram of the geological exploration data provided in an embodiment of this application. (Refer to...) Figure 2 As shown, geological exploration data may include, for example, exploration boreholes, foundation pit boundary control points, and the excavation depth at the bottom of the foundation pit.
[0048] Exploration boreholes can pinpoint the exact location of each exploration point within the site, enabling the construction of a geological model of the site, including information such as soil layer distribution and depth. Boundary control points define the boundaries of the excavation pit, providing precise boundary references for excavation design and construction. The depth of the excavation bottom is a key parameter for assessing soil stress changes and the stress on the pipe piles during excavation.
[0049] Furthermore, in the prediction of pile deviation risk, the geological exploration data obtained may also include: the silt layer burial depth of the exploration boreholes and the silt layer burial depth of the foundation pit boundary control points. The silt layer burial depth of the exploration boreholes can determine the specific depth of the silt layer at different exploration borehole locations, reflecting the thickness and distribution pattern of the silt layer. The silt layer burial depth of the foundation pit boundary control points can determine the geological conditions at the foundation pit boundary, which is crucial for assessing the lateral earth pressure on the piles during foundation pit excavation. It should be noted that the types of geological exploration data mentioned are merely illustrative and are not intended to be an exhaustive list of all types of geological exploration data.
[0050] It is understood that the above description of obtaining geological survey data and construction data of pipe piles for the target site is merely exemplary. Those skilled in the art can select and set the geological survey data and construction data of pipe piles for the target site according to actual needs, as long as the technical principles of this application can be realized.
[0051] S102. Based on the geological exploration data, construct a triangular mesh model of the silt layer in the excavation area of the foundation pit.
[0052] Specifically, the locations of key nodes can be determined through boreholes and control points at the foundation pit boundary. By combining the silt layer depth data from the boreholes and control points, corresponding depth information is assigned to each key node, reflecting the thickness variations of the silt layer at different locations. Using these key nodes with depth information, a triangular mesh is generated, for example, through calculation and interpolation methods. Each triangular cell consists of three adjacent nodes, and the shape and size of the mesh are adjusted according to the distribution and depth differences of the key nodes. This triangular mesh model can accurately display the actual topographic features of the silt layer.
[0053] Optionally, in some embodiments, constructing a triangular mesh model of the silt layer within the excavation area of the foundation pit includes: triangulating the excavation surface of the foundation pit to be inspected with the exploration hole as the vertex of the triangle to obtain a first triangular mesh; triangulating the excavation surface of the foundation pit to be inspected with the exploration hole, the foundation pit boundary control point, and the first intersection point as the vertices of the triangle to obtain a second triangular mesh, wherein the first intersection point is the intersection of the excavation boundary of the foundation pit to be inspected and the mesh line in the first triangular mesh, and the excavation boundary is the boundary of the single connected plane formed by the foundation pit boundary control point; deleting the triangular meshes of the second triangular mesh other than those at the foundation pit boundary control point and the first intersection point to obtain a triangular mesh model of the silt layer within the excavation area of the foundation pit.
[0054] Specifically, Figure 3 This is a schematic diagram of the structure of the first triangular mesh provided in an embodiment of this application. (Refer to...) Figure 2 and Figure 3 The vertices of the first triangular mesh can be determined based on the exploration holes. The excavation surface of the pit to be tested is triangulated by each vertex to obtain the first triangular mesh.
[0055] By using the exploration boreholes, the control points at the foundation pit boundary, and the first intersection point formed by the intersection of the foundation pit excavation boundary and the grid lines in the first triangular mesh as the vertices of the triangles, the excavation surface of the foundation pit to be inspected is further triangulated to obtain a second triangular mesh. The second triangular mesh not only includes the boundary control points of the foundation pit, but also determines the intersection points of the excavation boundary and the original triangular mesh lines, thus generating a triangular mesh that more closely matches the actual excavation area boundary.
[0056] Figure 4 This is a schematic diagram of the intersection point between the excavation boundary of the pit to be inspected and the first triangular mesh, provided as an embodiment of this application. (Refer to...) Figure 4 The excavation boundary can be formed by continuous, simply connected planar boundaries from the foundation pit boundary control points, thereby ensuring the integrity and accuracy of the foundation pit excavation area. The first intersection point can be, for example, the intersection point between the excavation boundary and the grid lines in the first triangular mesh, used to optimize and refine the triangular mesh.
[0057] Finally, the second triangular mesh can be filtered, retaining the triangular meshes located between the control points of the foundation pit boundary and the first intersection point. These triangular meshes directly connect to the excavation boundary of the foundation pit, which is crucial for analyzing the soil stress changes and pile stress conditions in the silt layer within the excavation area. By eliminating meshes not directly related to the excavation boundary, a triangular mesh model for the silt layer within the excavation area is obtained. The specific generated triangular mesh model is as follows: Figure 5 As shown.
[0058] S103. Based on the construction data of the pipe piles, generate the plane coordinates of each pipe pile.
[0059] Specifically, the construction data for pipe piles can include their exact installation locations and depths on the construction site. By measuring and recording this information, a planar distribution map of the pipe piles within the excavation area can be constructed. This planar distribution map not only shows the location of the pipe piles but can also be combined with the constructed triangular mesh model of the silt layer to provide crucial data support for analyzing the lateral earth pressures that the pipe piles may experience during excavation and their stability. Furthermore, the generation of planar coordinates facilitates the prediction of interactions between pipe piles and the relationship between each pipe pile and the excavation support structure.
[0060] S104. Based on the plane coordinates of each of the pipe piles and the triangular mesh model, determine the silt layer burial depth at the plane coordinates of each of the pipe piles.
[0061] Specifically, the planar coordinates of each pipe pile can be matched with the triangular mesh model to find the mesh cell corresponding to each coordinate point. Then, based on the depth information of the silt layer, the burial depth of the silt layer at each pipe pile location can be calculated.
[0062] In this process, interpolation algorithms can be used for calculation because the actual depth of the silt layer may vary within the grid cells and needs to be calculated based on the depth data of surrounding known points. Interpolation algorithms can provide accurate silt layer depth for each pipe pile. Figure 6 This is a structural schematic diagram illustrating the spatial relationship between the pipe pile and the silt layer provided in an embodiment of this application. The spatial relationship diagram between the pipe pile and the silt layer can be obtained through step S104, as detailed in the following reference. Figure 6 .
[0063] Optionally, in some embodiments, determining the silt layer burial depth at the plane coordinates of each pipe pile based on the plane coordinates of each pipe pile and the triangular mesh model may include: determining the triangle in which the plane coordinates of the pipe pile are located in the triangular mesh model; and obtaining the silt layer burial depth at the plane coordinates of the pipe pile according to the coordinates of each vertex of the triangle and the silt layer burial depth corresponding to each vertex coordinate.
[0064] Specifically, the plane coordinates of each pipe pile can be determined in the triangle of the triangular mesh model. After determining the triangle, the burial depth of the silt layer at the plane coordinates of the pipe pile can be calculated based on the coordinates of each vertex of the triangle and the burial depth of the silt layer corresponding to each vertex coordinate.
[0065] For example, suppose the coordinates of the three vertices of a triangle and their corresponding silt layer depths are as follows: Vertex A has coordinates (x1, y1) and a silt layer depth of h1; Vertex B has coordinates (x2, y2) and a silt layer depth of h2; Vertex C has coordinates (x3, y3) and a silt layer depth of h3. We need to calculate the plane coordinates of a point P located inside this triangle (i.e., the pipe pile). This can be achieved by determining the position of point P relative to the vertices of the triangle, for example, by calculating the directed distances from point P to each side of the triangle, or by using barycentric coordinates to represent the position of point P within the triangle. Knowing the proportion of point P's position within the triangle, we can use a linear interpolation formula to calculate the silt layer depth of point P.
[0066]
[0067] in, , and Let P be the coordinates of the centroid of the triangle, which must satisfy... + + =1.
[0068] By substituting the silt layer burial depth at the vertex and the corresponding centroid coordinates into the formula, the silt layer burial depth at point P can be calculated. .
[0069] It is understandable that interpolation calculations can be linear or based on mathematical models, such as polynomial interpolation or spline interpolation. The specific interpolation method chosen can be selected according to actual needs.
[0070] Optionally, in some embodiments, determining the silt layer depth corresponding to the coordinates of each vertex may include: if the vertex of the triangle is an exploration hole, then the silt layer depth of the exploration hole is the silt layer depth corresponding to the vertex coordinates; if the vertex of the triangle is the foundation pit boundary control point, then the foundation pit boundary control point is the silt layer depth corresponding to the vertex coordinates; if the vertex of the triangle is a boundary intersection point, the silt layer depth corresponding to the vertex coordinates is determined by linear interpolation of the silt layer depth of the exploration hole at the two endpoints of the grid edge of the first triangular mesh to which it belongs; if the vertex of the triangle is the first intersection point, the silt layer depth of the hole corresponding to the vertex coordinates is the silt layer depth of the intersection point of the corresponding first intersection point.
[0071] Specifically, in one scenario, if the vertex of the triangle represents the location of the borehole, the silt layer depth of the borehole can be directly used as the silt layer depth corresponding to the vertex coordinates. For a given vertex, this can reflect the actual depth of the silt layer at the borehole location.
[0072] In another scenario, the excavation pit boundary control points are the boundary definition points of the excavation area. These boundary definition points clearly define the extent and shape of the pit and can serve as important vertices in constructing a triangular mesh model describing the geological characteristics of the excavation area. Excavation pit boundary control points are key reference points in the engineering design and construction process, closely related to the pit design, support structure, and subsequent construction activities. Using the excavation pit boundary control points as vertices of the triangular mesh can better reflect the actual construction environment.
[0073] In another scenario, when the vertices of the triangle are boundary intersections, these intersections are the points where the excavation boundary of the foundation pit intersects with the grid lines in the first triangular mesh. Since these boundary intersections may not directly correspond to the locations of existing boreholes, linear interpolation can be used to determine the silt layer depth at the boundary intersections. Specifically, the exact location of the boundary intersections within the first triangular mesh can be determined first. Then, the boreholes adjacent to the boundary intersections can be identified. These boreholes can be located at the two endpoints of the grid edges. Silt layer depth data is collected based on these boreholes, as the silt layer depth data is known because it corresponds to the actual borehole locations. Finally, the silt layer depth at the boundary intersections is calculated using linear interpolation based on the silt layer depths of adjacent boreholes.
[0074] In another scenario, if the vertices of the triangles are the first intersection points, these intersection points are formed by the intersection of the excavation boundary of the foundation pit with the grid lines in the first triangular mesh. The silt layer depth corresponding to the vertex coordinates is the silt layer depth at the first intersection point.
[0075] Optionally, in some embodiments, determining the silt layer burial depth at the plane coordinates of the pipe pile includes the following formula:
[0076]
[0077]
[0078] in, The depth of the boundary point on the silt layer at the plane coordinates of the pipe pile. , , , The correlation coefficients between the depth of the lower boundary point of the silt layer at the plane coordinates of the pipe pile and the coordinates of the vertices of the triangle, and the correlation coefficient between the depth of the lower boundary point of the silt layer at the vertices, are given. The depth of the boundary point on the silt layer at the plane coordinates of the pipe pile. , , , The correlation coefficient between the depth of the boundary point on the silt layer at the plane coordinate of the pipe pile and the coordinate of the vertex of the triangle, and the correlation coefficient between the depth of the boundary point on the silt layer at the vertex, where X and Y are the X coordinate and Y coordinate at the plane coordinate of the pipe pile, respectively.
[0079] in,
[0080]
[0081]
[0082]
[0083] , , These are the X coordinates of the vertices of the triangle. , , These are the Y-coordinates of the vertices of the triangle. , , The depths of the silt layer below the vertices of the triangle are respectively the depths of the dividing points.
[0084] Optionally, in some embodiments, determining the burial depth of the silt layer at the first intersection point may include the following formula:
[0085]
[0086] in, The depth of the boundary point on the silt layer at the first intersection point. The depth of the boundary point below the first intersection point silt layer. The first endpoint of the grid line in the first triangular grid to which the first intersection point belongs is the boundary point on the surface of the silt layer. The boundary point on the silt layer corresponding to the second endpoint of the grid line in the first triangular grid to which the first intersection point belongs. The first endpoint of the grid line in the first triangular grid to which the first intersection point belongs corresponds to the lower boundary point of the exploration silt layer. The second endpoint of the grid line in the first triangular grid to which the first intersection point belongs is the lower boundary point of the exploration silt layer.
[0087] S105. Based on the silt layer burial depth at the plane coordinates of each pipe pile, the pile body parameters of each pipe pile, and the excavation depth of the foundation pit, determine the pile deviation risk of each pipe pile.
[0088] Specifically, based on the silt layer depth at the location of the pipe piles, as determined above, and then combining this with the pile body parameters of each pipe pile and the excavation depth of the foundation pit, the risk level of pile deviation for each pipe pile can be determined. The pile body parameters may include, for example, the pipe pile's diameter, length, material, and wall thickness, which may affect the pile's bearing capacity and lateral displacement resistance. Furthermore, based on the calculated risk level of pile deviation, different levels can be assigned, such as low risk, medium risk, and high risk. Figure 7 This diagram illustrates the predicted risk of pile deviation for each of the pipe piles described in the embodiments of this application. Each point in the diagram represents the location of a pipe pile. The darker the red, the higher the risk of pile deviation. By analyzing the colors, the overall distribution of pile deviation risk within the entire foundation pit area can be understood, and areas with higher risk can be identified. (Refer to...) Figure 7 By using color, one can understand the different degrees of pile deviation risk, thereby understanding the risk distribution of each pipe pile within the foundation pit area.
[0089] Optionally, in some embodiments, determining the risk of pile deviation for each of the pipe piles includes the following formula:
[0090]
[0091] in, Let a and b be the risk degree of pile deviation of the pipe pile, respectively. The length of the pipe pile in the silt layer. The length of the pipe pile from the bottom of the excavation pit upwards. The height of the pipe pile is given.
[0092] in,
[0093]
[0094]
[0095]
[0096]
[0097] This refers to the embedment depth of the pipe pile at its highest point in the silt layer. This refers to the depth of the lowest point of the pipe pile in the silt layer. The length of the pipe pile from the bottom of the excavation pit upwards. This is the elevation of the bottom of the pipe pile. This refers to the elevation of the top of the pipe pile. The depth of the boundary point on the silt layer at the plane coordinates of the pipe pile. The depth of the boundary point below the silt layer at the plane coordinates of the pipe pile. This refers to the depth of the excavation at the bottom of the foundation pit.
[0098] In summary, the pipe pile deviation risk prediction method 100 provided in this application embodiment acquires geological survey data and pipe pile construction data of the target site, and constructs a triangular mesh model of the silt layer within the excavation area of the foundation pit. The triangular mesh model reflects the spatial distribution characteristics of the silt layer. Simultaneously, it generates the plane coordinates of each pipe pile based on the construction data, and determines the silt layer burial depth at each pipe pile using the triangular mesh model. Based on the silt layer burial depth, pipe pile body parameters, and the excavation depth at the bottom of the foundation pit, it calculates the deviation risk of each pipe pile. The pipe pile deviation risk prediction method provided in this application embodiment achieves a quantitative assessment of the pipe pile deviation risk in silt layer sites and a quantitative analysis of the pipe pile deviation risk before foundation pit excavation, providing data-driven guidance for refined excavation of foundation pits and ensuring construction quality. Furthermore, by identifying and quantifying deviation risks in advance, the construction team can optimize the construction plan, rationally arrange the construction sequence and support measures, thereby reducing construction risks.
