Description

Technical Field

[0001] The present invention relates to the technical field of slope stability analysis, and more specifically to a slope stability analysis method. Background Art

[0002] In recent years, tower foundation instability incidents caused by slope damage have occurred from time to time. There are two main types of traditional numerical analysis methods for slope stability. One is to analyze its stability based on a two-dimensional slope model. This method replaces the three-dimensional model with a two-dimensional model when analyzing the slope model. The modeling difficulty and calculation amount are significantly reduced, but its simulation effect on the real environment will also be greatly reduced. Slope landslides are often a development process from point to line and then to surface. The points on the two-dimensional slope cannot accurately replace the points in the three-dimensional space, and the slope structure is oversimplified. Therefore, the stability analysis method based on the two-dimensional slope model has doubts about its results and has little reference value for slope stability in actual three-dimensional scenes. The other type is a fine slope model obtained by high-precision data acquisition means. This type of model is a high-precision replica of the real environment, highlighting various details of the entire slope environment. Therefore, the slope stability analysis results obtained based on this type of model will be closer to reality and have high credibility. However, this type of model often faces the problems of high modeling difficulty, large calculation amount and easy non-convergence, which seriously restricts the efficiency of slope stability analysis. Both of these methods are not conducive to the development of slope stability research based on numerical analysis. Summary of the invention

[0025] Figure 1 A flow chart of a slope stability analysis method according to an embodiment of the present invention is schematically shown. Figure 1 As shown, an embodiment of the present invention provides a slope stability analysis method, including: collecting point cloud data of the slope environment; converting the point cloud data into a set of slope contour lines; using the set of slope contour lines to construct a set of slope models, and performing stability analysis on the set of slope models.

[0026] In this embodiment, a suitable method is selected to collect slope environment point cloud data according to the characteristics of the on-site environment.

[0027] Through the embodiments of the present invention, a simplified slope stability analysis method is proposed based on the real-life scenic spot cloud, which combines the advantages of the two-dimensional slope model, which is simple to model and has low computational complexity, with the three-dimensional model, which has high accuracy in slope stability analysis. Based on the idea of ​​sampling, a three-dimensional slope stability analysis model is converted into a set of two-dimensional slope stability analysis models.

[0028] On the basis of the above embodiment, the point cloud data is converted into a set of slope contour lines, including: aligning the point cloud data in a three-dimensional coordinate system; the y-axis of the three-dimensional coordinate system is located in the horizontal plane of the slope environment and parallel to the extension direction of the slope environment, the x-axis of the three-dimensional coordinate system is located in the horizontal plane and perpendicular to the y-axis, and the z-axis of the three-dimensional coordinate system is perpendicular to the horizontal plane; using the intersection points of multiple virtual planes and the point cloud data to obtain corresponding multiple initial contour lines; wherein the virtual plane is parallel to the y-axis and perpendicular to the horizontal plane; selecting a reference contour line from the multiple initial contour lines, and regularizing the multiple initial contour lines according to the reference contour line; screening the multiple initial contour lines to obtain a set of slope contour lines.

[0029] In this embodiment, Figure 2 A flowchart of converting the point cloud data into a set of slope contour lines according to an embodiment of the present invention is schematically shown. Figure 2 As shown in the figure, firstly, the uniform point cloud data of the entire slope environment is sampled uniformly and discretely with high density, and the data points are divided into high-density parallel from the top to the bottom of the slope according to the slope range to obtain the initial contour line, which ensures the integrity of the basic data information of the slope and converts the three-dimensional slope data (such as Figure 3 The three-dimensional slope model based on point cloud data shown in the figure is converted into a set of two-dimensional slope point cloud data, and the three-dimensional slope stability analysis problem is converted into a set of two-dimensional slope stability analysis problems, and the initial contour line of the slope section is established; secondly, the discretized two-dimensional slope data is unified on the specified coordinate components through contour line regularization, so that the contour line can be merged to merge the contour lines with similar or identical structural features into one, realize the integration of the initial contour lines, and obtain the slope contour line, which greatly reduces the amount of discretized two-dimensional slope data, reduces the modeling workload, and improves the efficiency of stability analysis; finally, the overall stability of the slope is analyzed based on the merged contour line.

[0030] In this embodiment, based on the three-dimensional data coordinates of the slope, the coverage range S = {(x, y)x∈[a, b], y∈[c, d]} of the slope environment in the horizontal projection direction (horizontal plane) is established. It is set to perform slope sampling once per distance e on the x-coordinate axis. The value of e is generally small, so that the initial contour line obtained by sampling can cover the main features of the slope, such as Figure 4 shown.

[0031] Through the embodiments of the present invention, data points with special structures in the three-dimensional environment of the entire slope are completely extracted by integrating high-density sampling and contour lines, one slope contour line represents the local slope environment, and multiple slope contour lines represent the overall slope environment. The three-dimensional model analysis problem is converted into a set of two-dimensional model analysis problems, and the amount of data, modeling difficulty, and calculation amount will be greatly reduced, and the analysis efficiency will be significantly improved.

[0032] On the basis of the above embodiment, the regularization of the multiple initial contour lines according to the reference contour line includes: using the interpolation method on the initial contour lines, and obtaining the z-axis coordinate of each corresponding point on the initial contour line according to each point on the reference contour line; wherein the y-axis coordinate of each corresponding point is consistent with the corresponding point on the reference contour line.

[0033] In this embodiment, since the positions of the points on each initial contour line are different, in order to merge the initial contour lines, a reference contour line l0{(x0=g0, y i0 z i0 )}, generally select the initial contour line with more data points as the reference contour line, use the interpolation method to regularize the points on all other initial contour lines, so that the coordinates of the initial contour lines are consistent in the direction parallel to the slope (y-axis direction) (that is, each point on the reference contour line has a point with the same y-axis coordinate on other initial contour lines), and solve the z-axis coordinates of the points on the initial contour line with the same y-axis coordinates and known x-axis coordinates m The formula is as follows:

[0034]

[0035] Among them, Figure 5 As shown, M0(g, y0, z0) is the coordinate of a known point on the reference contour line; the coordinate of the point M to be obtained by interpolation is (g m ,y m , z m ), where y m =y0; the coordinates of the two known points adjacent to point M on this initial contour line are P f (g f ,y f , z f ), P b (g b ,y b , z b ).

[0036] Through the embodiments of the present invention, all initial contour lines are regularized according to the reference contour line so that the x-axis coordinate difference of each initial contour line is the distance of parallel division, and each initial contour line has a corresponding point on the y-axis with the same coordinates as each point of the reference contour line, so that the z-axis coordinate can characterize the difference characteristics of each initial contour line.

[0037] On the basis of the above embodiment, the screening of the multiple initial contour lines includes: taking the first initial contour line as the current contour line, recording the current contour line as a slope contour line, and detecting whether there is a next contour line; if not, completing the screening of the multiple initial contour lines; if so, detecting whether the mean square error between the z-axis coordinates of all points on the current contour line and the z-axis coordinates of all points on the next contour line is greater than a preset threshold; if so, taking the next contour line as the current contour line, and executing the recording of the current contour line as a slope contour line; if not, deleting the next contour line, and executing the detection of whether there is a next contour line.

[0038] It should be noted that the current contour line can also be selected from the middle or the other end. After the initial contour line in the middle is selected as the current contour line, the contour lines are merged in two directions respectively.

[0039] In this embodiment, since the division density of the initial contour lines is high, a large number of contour lines are approximately consistent. After the contour lines are regularized, they are screened based on the mean square error of the z-axis coordinates of the two initial contour lines. Only one contour line with higher similarity is retained, and the cycle is repeated until all contour lines are screened.

[0040] The mean square error is calculated as follows: Taking the reference contour line as an example, after regularizing the contour line in the direction of the y coordinate component, the reference contour line is used as the starting reference to solve the adjacent contour line l1{(x1=g1, y i1 , z i1 )}, where y i1 =y i0 , and the reference contour line l0{(x0=g0,y i0 , z i0 The formula for solving the mean square error between the reference contour line and the adjacent contour line is as follows:

[0041]

[0042] When the mean square error D is less than the set threshold, the data of the initial contour line does not need additional stability analysis, and only the reference contour line is considered when establishing the slope model through stability analysis; when the mean square error D is greater than the set threshold, the data of the initial contour line needs to be separately analyzed for stability, and the next adjacent contour line is selected to calculate the mean square error with the initial contour line, and the cycle is repeated until all contour lines have been compared with the mean square error, and the slope contour lines for which the slope model needs to be established are screened out.

[0043] Through the embodiments of the present invention, data points with special structures in the three-dimensional environment of the entire slope are completely extracted by contour line screening, and a slope contour line represents the local slope environment. The overall slope environment is characterized by all the screened slope contour lines, thereby improving the analysis efficiency while ensuring the quality of the analysis.

[0044] On the basis of the above embodiment, after the stability analysis is performed on the group of slope models, it also includes: performing multiple acquisitions of point cloud data of the slope environment, converting the point cloud data into a group of slope contour lines, constructing a group of slope models using the group of slope contour lines, and performing stability analysis on the group of slope models; extracting slope models whose stability coefficients are lower than a preset threshold in multiple analyses as key models for slope stability analysis.

[0045] Through the embodiments of the present invention, a slope model with hidden dangers or a low safety factor is extracted as a core object for slope stability evaluation, thereby improving the efficiency of slope environmental stability analysis.

[0046] Based on the above slope stability analysis method, the present invention also provides a slope stability analysis device, which is configured to be used to implement the above slope stability analysis method. Figure 6 The device is described in detail.
