[0063] In Figure 1 In the slope connection model design device shown, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the slope connection model design device can be arranged in the slope connection model design device, and the slope connection model design device calls the slope connection model design program stored in the memory 1005 through the processor 1001, and executes the slope connection model design method provided in the embodiments of the present application.

[0064] The embodiments of the present application provide a slope connection model design method, which refers to Figure 2 , Figure 2 The flowchart of the first embodiment of the slope connection model design method of the present application is shown.

[0065] In this embodiment, the slope connection model design method includes the following steps:

[0066] Step S10: Obtain the edge section line of the adjacent slope in the subgrade slope model, and obtain the azimuth angle of the adjacent edge section line according to the edge section line.

[0067] It can be understood that the subgrade slope model can be a model constructed according to a road or a bridge, but there is a slope that does not connect in the subgrade slope model. The slope in the subgrade model can be understood as the slope of the road model, which refers to the inclined surface connecting the two sides of the road cross section with the ground, including embankment slope and cutting slope, which is an important factor affecting the stability of the subgrade. The connected slope can be obtained by connecting two slopes with height difference, for example, the bridge-road connection slope can refer to Figure 3 .

[0068] It should be understood that the edge section line can be a line segment representing the slope section in the subgrade model.

[0069] It should be noted that the edge section line of the adjacent slope in the subgrade slope model is obtained, and the azimuth angle of the adjacent edge section line is obtained according to the edge section line, including: obtaining the edge section line of the adjacent slope in the subgrade slope model; obtaining the connection point of the adjacent edge section line according to the edge section line; obtaining the azimuth angle of the adjacent edge section line according to the connection point of the edge section line and the adjacent edge section line; obtaining the slope connection direction of the adjacent slope in the subgrade slope model; and obtaining the azimuth angle of the adjacent edge section line according to the slope connection direction and the azimuth angle.

[0070] It should be noted that the edge section line, the connection point, the azimuth angle, the slope connection direction and the azimuth angle can be referred to Figure 4 . In the figure, u1 and v1 are adjacent edge section lines, u2 and v2 are adjacent edge section lines, and the slopes formed by u1 and u2 and the slopes formed by v1 and v2 are adjacent slopes. u1, v1, u2 and v2 are edge section lines, and the intersection of u1 and v1 can be understood as a connection point. The connection direction of the slope is as shown in Figure 4 , and the connection direction of the slope can be in a clockwise direction, and other connection directions can be selected, which are not limited in the embodiment and can be adjusted according to actual conditions. θ1 and θ2 can be understood as the azimuth angle of the adjacent edge section lines.

[0071] It should be further noted that the azimuth angle of the adjacent edge section line obtained according to the edge section line and the connection point of the adjacent edge section line includes: obtaining the start point coordinates and the end point coordinates of the adjacent edge section line; obtaining the direction vector of the adjacent edge section line according to the connection point, the start point coordinates and the end point coordinates; and obtaining the azimuth angle based on the direction vector of the adjacent edge section line.

[0072] It can be understood that a three-dimensional coordinate system can be constructed according to the entire model, or a coordinate system can be established with the slope section line and the corresponding connection point as the origin and the coordinate axis to obtain the start point coordinates and the end point coordinates of the adjacent edge section line, and then the direction vector of the to-be-connected slope edge section line is calculated by the start point and end point coordinates of the slope section line, and the azimuth angle of the adjacent edge section line is calculated by the vector formula.

[0073] It should be noted that the execution subject of the embodiment is a slope connection model design device, which has functions of data processing, data communication and program running, and the slope connection model design device can be an integrated controller, a control computer or other devices with similar functions, which are not limited in the embodiment.

[0074] Step S20: obtaining the connection section line of the to-be-connected region based on the preset connection angle and the azimuth angle.

[0075] It can be understood that the preset connection angle is a preset angle that is used to divide the azimuth angle between the adjacent edge section lines into multiple to-be-connected slope edge section lines with a preset connection angle.

[0076] It should be noted that the preset connection angle and the slope section line can be referred to Figure 5 , and in the figure, △θ1 can be understood as the preset connection angle, or the azimuth angle between the adjacent edge section lines can be directly divided into △θ1.

[0077] It should be noted that the two line areas formed by the reference Figure 5 The two line areas formed by the reference

[0078] Step S30: Network modeling according to the reference

[0079] It should be noted that the network modeling according to the reference

[0080] It should be emphasized that network modeling can be based on a three-dimensional terrain model, using professional modeling software or tools based on lines to model, converting the designed slope connection scheme into a digital model, including the geometry, material properties, etc. of the slope.

[0081] In specific implementation, the complete flowchart of the slope connection model design can refer to Figure 6 The direction vectors of the two slope edge section lines to be connected can be calculated, and the azimuth angle between the two slope edge section lines to be connected can be calculated to determine the slope connection modeling direction, calculate the azimuth angle of the slope section line in the slope connection modeling section, calculate the slope section line in the connection section, and network modeling according to the connection slope section line.

[0082] This embodiment determines the azimuth angle of the slope connection model through the angle between the adjacent slopes of the roadbed slope model, determines the network direction of the connection modeling according to the adjustable azimuth angle, determines the connection section line of the area to be connected and the ground line in the area according to the connection direction and the slope connection section line, and creates a non-standard slope connection model with a constantly changing line direction angle between the adjacent slopes in the roadbed slope model according to the connection section line.

[0083] Reference Figure 7 , Figure 7 The flowchart of the second embodiment of the slope connection model design method of the present application.

[0084] Based on the above first embodiment, the slope connection model design method of the present embodiment comprises the following steps:

[0085] Step S21: Obtain the connection point coordinates of the adjacent edge section lines, and obtain the azimuth angle of each connection section line according to the preset connection angle and the azimuth angle.

[0086] It can be understood that there can be multiple junction points and multiple adjacent edge section lines in the slope model, the azimuth angles of the adjacent edge section lines are different in size, and it can be seen that the included angles of the junction section lines can be the same or different.

[0087] It should be noted that the preset junction included angle can be a fixed angle size preset in advance, or can be obtained by equally dividing the azimuth angle size, and the angle size can be divided by 8, 16, etc., which can be set according to actual needs, and the embodiment is not limited thereto.

[0088] Step S22: obtaining a junction section line control point coordinate according to the junction point coordinate and the junction section line included angle.

[0089] It should be noted that obtaining a junction section line control point coordinate according to the junction point coordinate and the junction section line included angle can be obtaining a hierarchical distance between the junction section line control point and the junction point according to the slope ratio and the slope hierarchical height of the adjacent slope in the subgrade slope model; obtaining a horizontal coordinate of the junction section line point according to the horizontal coordinate of the junction point coordinate, the junction section line included angle and the hierarchical distance; obtaining a vertical coordinate of the junction section line point according to the vertical coordinate of the junction point coordinate, the junction section line included angle and the hierarchical distance; obtaining a vertical coordinate of the junction section line point according to the vertical coordinate of the junction point coordinate and the hierarchical distance; and obtaining a junction section line control point coordinate according to the horizontal coordinate of the junction section line point, the vertical coordinate of the junction section line point and the vertical coordinate of the junction section line point.

[0090] It should be noted that the shape of the slope is often constructed into a single slope, a polyline and a ladder in the subgrade, and the slope of each slope section is represented by the ratio of the height difference between the upper and lower points on the slope section diagram to the horizontal distance. In the subgrade engineering, the slope represented in the form of 1:m is called the slope, and m is called the slope rate. The height, shape and slope of the slope have an important influence on the stability of the subgrade body and the engineering cost.

[0091] It should be noted that the slope hierarchical height refers to the division of the slope into different levels according to the height of the slope, so as to reasonably plan and take corresponding engineering measures during design and construction. Generally speaking, in the railway industry, when the vertical height of the slope is greater than 8 meters, the slope is graded. In addition, the hierarchical height of the slope can also be different according to the difference between the filling and the excavation.

[0092] It should be noted that the slope grading distance generally refers to the horizontal segment length of the slope, also known as the grading width or slope segment length of the slope, and is related to factors such as the height, slope, geological conditions, protection measures and drainage design of the slope; the setting of the slope grading distance helps to control the stability of the slope and reduce the potential landslide risk. A reasonable grading distance can be determined according to the geological exploration report and the stability analysis of the slope. At the same time, the actual situation on site, such as the topography, underground water level, rainfall conditions and other factors, is also considered.

[0093] In specific implementation, taking the calculation of the i-th connecting slope section line as an example, the calculation of the azimuth angle of the connecting section line can refer to Figure 4 、 Figure 5 In the figure, if the direction vector v1 of the edge line of the embankment slope is α, then the azimuth angle of the i-th connecting slope line can be expressed as α±i*△θ1 (considering the equal angle, and selecting + or - according to the azimuth rotation rule). The coordinates of the slope control point are calculated according to the coordinates of the connecting point, the azimuth angle of the slope section line, the grading height of the slope and the slope ratio.

[0094] In specific implementation, taking a 2-grade slope as an example, the calculation of the coordinates of the connecting section line control point can refer to Figure 8 , wherein O is the connecting point, and A1, B1 and C1 represent a plurality of control points of the first connecting section line. According to Figure 8 , the distance La from the point A to the connecting point O of the slope is H1*m (1: m is the slope ratio); given that the coordinates of the connecting point O of the slope are (Xo, Yo, Zo), and the azimuth angle of the slope section line is α±i*△θ1, the coordinates of the slope section control point A1 can be calculated according to the following formula:

[0095] Xa=Xo+Sin(α±i*△θ1+0.5*π)*La

[0096] Ya=Yo+Cos(α±i*△θ1+0.5*π)*La

[0097] Za=Zo±H1

[0098] The coordinates of B1 and C1 can be further calculated according to the calculation method of the coordinates of the slope section control point A1.

[0099] Step S23: obtaining an initial connecting section line based on the coordinates of the connecting section line control points.

[0100] It can be understood that the initial connecting section line can be obtained by sequentially connecting the plurality of connecting section line control points calculated.

[0101] In specific implementation, the following formula can be referred to: Figure 8The initial connection cross-section line can be obtained by connecting O, A1, B1 and C1 in sequence according to the coordinate points calculated according to A1, B1 and C1.

[0102] It should be noted that the initial connection cross-section line based on the connection cross-section line control point coordinates comprises: obtaining the slope grading height and slope ratio in the roadbed slope model; determining the number of connection cross-section line control points according to the grading height and the slope ratio; and obtaining the initial connection cross-section line based on the number of connection cross-section line control points and the connection cross-section line control point coordinates.

[0103] It should be understood that different slope grading heights and slope ratios have certain influence on the number of control points of the connection cross-section line in the construction of the slope connection model, for example, the higher the slope grading height, the more control points of the connection cross-section line, and the number of control points to be set can be determined before the calculation of the connection cross-section line control points, and the initial connection cross-section line is calculated based on the number of control points and the slope ratio.

[0104] Step S24: obtaining the ground line in the roadbed slope model, and cutting the initial connection cross-section line according to the ground point to obtain the connection cross-section line of the region to be connected.

[0105] It should be understood that the initial connection cross-section line is a mathematical line segment length calculated according to the connection cross-section line, but the connection cross-section line needs to be connected to the ground in the actual construction process, and the ground is uneven, and the data calculation length of the connection cross-section line may be longer than, equal to or shorter than the actual length in the construction.

[0106] It should be understood that the initial connection cross-section line can be cut in combination with the ground line of the region to be connected to obtain the connection cross-section line that fits the ground of the region to be connected.

[0107] It should be noted that the initial connection cross-section line based on the connection cross-section line control point coordinates comprises: obtaining the ground line in the roadbed slope model; calculating the intersection point between the ground line and the initial connection cross-section line; and cutting the initial connection cross-section line according to the intersection point to obtain the connection cross-section line of the region to be connected.

[0108] In a specific implementation, the initial connection cross-section line is obtained based on the connection cross-section line control point coordinates. Figure 8 The initial slope cross-section line can be obtained by connecting O, A1, B1 and C1, the ground line at the position of the slope cross-section is obtained according to the ground model, the slope cross-section line is cut (the intersection point of the slope line and the ground is obtained, and the slope cross-section line passing through the ground line beyond the intersection point is cut off), and the final slope cross-section line OA1B1C1' to be modeled is obtained, and the connection cross-section line after the intersection and cutting of the slope cross-section line and the ground can be referred to as Figure 9The edge slope section line set can be referenced based on the cut interface line Figure 10 .

[0109] The embodiment calculates the included angle of each interface section through the interface point coordinates and the azimuth angle, and then calculates the interface section line control point coordinates through the interface section included angle. The initial interface section line is formed according to the plurality of interface section line control point coordinates. In order to avoid that the initial interface section line does not fit the ground model when modeling, the initial interface section line is cut through the ground line of the region to be connected, so that a more accurate interface section line is obtained. The problems of uncontrollable connection direction and low connection accuracy of the existing slope connection model design method are solved, and the efficiency and accuracy of the slope connection model design method are improved.
