Description

Technical Field

[0001] The present invention relates to the field of geotechnical engineering design, and particularly to an automatic design method and system for a rockfall interception and diversion pile-plate wall in mountainous areas. Background Art

[0002] In the design of rockfall protection for mountain railways, in order to avoid threats to the safety of railway operation caused by rockfalls, a rockfall interception and diversion pile-plate wall (hereinafter referred to as the interception wall) is usually used to intercept, guide and divert rockfalls, such as Figure 1 . The interception wall mainly consists of anchor piles, inter-pile plates and rockfall diversion troughs, such as Figure 2 .

[0003] The current design of the interception wall is based on two-dimensional plan and section drawings. The plan is a topographic map, and the section is the measured control section passing through the designed area, usually only 3 to 5 measured sections. First, determine the layout position of the interception wall and the required pile length for each section through the control section, then determine the plane layout position according to the position of the interception wall in each section, and then draw the front view of the interception wall through the plane layout position, such as Figure 3 . At the same time, design data such as diversion slope, diversion direction, and pile length are obtained. Finally, the designer judges, adjusts, and optimizes it, and reflects the optimized design scheme on the plan and section drawings, that is, modifies the plan and section drawings. The whole process is based on two-dimensional design, and when designing a single measured section, factors such as diversion direction and diversion slope cannot be considered. When the terrain changes rapidly, the number of measured sections is small, or the rockfall protection range is large, the above steps generally need to be repeated many times to obtain the final optimal rockfall diversion and protection scheme, which is time-consuming and laborious. Summary of the Invention

[0004] The present invention provides a three-dimensional automatic design method and system for a rockfall interception and diversion pile-plate wall in mountainous areas, which is applicable to the design of rockfall protection for mountain railways, and solves the problems of backward design method, low efficiency, and many repetitive tasks existing in the existing two-dimensional design.

[0005] In order to achieve the above invention purpose, the present invention provides the following technical solutions:

[0006] An automatic design method for a rockfall interception and diversion pile-plate wall in mountainous areas specifically includes the following steps:

[0007] S1, store the models and their dimensional parameters of the anchor piles and inter-pile plates in the interception wall in a model library;

[0008] S2, import terrain data to establish a three-dimensional terrain model, and select the boundary of the protection design range in the top view of the three-dimensional terrain model;

[0009] S3. According to the preset conditions, determine the layout points of the anchor piles in the retaining rock wall on the boundary of the protection design range by using the "linear layout method" or the "broken line layout method".

[0015] S33. Equally divide the alternative line segments at a fixed interval of the pile spacing S to obtain equally divided points.

[0016] S34. Project the equally divided points onto the ground of the 3D terrain model to obtain ground projection points, and obtain the 3D coordinates of each ground projection point.

[0017] S35. Calculate the slope between the equally divided points on the alternative line segments according to the 3D coordinates of the ground projection points, and determine whether the slope is within the allowable slope range.

[0018] S36. If the slopes between the equally divided points on the alternative line segments are all within the slope range, the 3D coordinates of the ground projection points are the layout points of the anchor piles in the retaining rock wall on the boundary of the protection design range.

[0022] A33. Project the equidistant points onto the ground of the three-dimensional terrain model to obtain ground projection points, and obtain the three-dimensional coordinates of each ground projection point;

[0023] A34. Calculate the slope between the equidistant points on the broken line according to the three-dimensional coordinates of the ground projection points, and determine whether the slope is within the allowable slope range;

[0024] A35. If the slope between the equidistant points on the broken line is within the allowable slope range, the three-dimensional coordinates of the ground projection points are the positions where the anchor piles in the rockfall retaining wall are arranged on the boundary of the protection design range; otherwise, prompt for modification and return to execute steps A31 - A34.

[0029] S44. Generate the three-dimensional model of the rockfall retaining wall in the three-dimensional terrain model according to the coordinates of the corner points of the anchor pile and the coordinates of the corner points of the slab between piles.

[0030] As a preferred solution of the present invention, in step S41, the three-dimensional coordinate calculation formula of the pile top P i of the anchor pile is:

[0042] P i7 : x i7 = xi3 ,y i7 = y i3 ,z i7 = z ip -L

[0043] P i8 : x i8 = x i4 ,y i8 = y i4 ,z i8 = z ip -L

[0045] As a preferred embodiment of the present invention, in step S43, the calculation formula for the corner coordinates of the slab between adjacent anchor piles at adjacent points is:

[0046] Qij1 : x ij1 = x ip , y ij1 = y ip + 0.5·H + k, z ij1 = z ip

[0071] The present invention will be further described in detail below in conjunction with test examples and specific implementation modes. However, this should not be construed as limiting the scope of the above-mentioned subject matter of the present invention to the following embodiments. Any technology implemented based on the content of the present invention belongs to the scope of the present invention.

[0072] Embodiment 1

[0073] A flow chart of a three-dimensional automatic design method for a mountainous area dangerous rock retaining and diverting pile-slab wall is as Figure 4 shown, and specifically includes the following steps:

[0074] S1. Store the models and their dimensional parameters of the anchor piles and the slab between piles in the retaining wall into the model library;

[0075] S2. Import terrain data to establish a three-dimensional terrain model, and select the boundary of the protection design range in the top view of the three-dimensional terrain model;

[0076] S3. According to preset conditions, use the "linear layout method" or the "broken line layout method" to determine the layout points of the anchor piles in the retaining wall on the boundary of the protection design range;

[0077] S4. Select the models of the anchor piles and the slab between piles from the model library, layout the anchor piles and the slab between piles on the three-dimensional terrain model according to the points, and complete the three-dimensional model design of the mountainous area dangerous rock retaining and diverting pile-slab wall.

[0078] The specific implementation methods of the above steps are as follows:

[0079] 1. Establish a model library

[0080] Input and store the common types of anchor piles and the slab between piles in the retaining wall and their corresponding dimensions, such as the cross-sectional height H, cross-sectional width B, pile length L of the anchor pile, and the slab thickness m of the slab between piles, into the model library.

[0081] 2. Import terrain data and select the boundary of the protection design range

[0082] Import terrain data and line data to establish a three-dimensional model, such as Figure 5 . Initially judge the protection range according to the terrain and the distribution position of dangerous rock falls, and specify the boundary ABCD of the retaining wall protection range in the top view, such as Figure 6, select the 3D terrain model within this projection range as the basis for subsequent design, such as Figure 7 .

[0083] 3. Setting Principles

[0084] Input the allowable range of the diversion slope i of the rock retaining wall [i min , i max , the minimum protection length R min , the pile spacing (center-center) d, the rock retaining height r 1 , the depth of the bottom plate embedded in the ground r 2 and other design principles.

[0085] Input the single search step angle θ.

[0086] 4. Selection Method

[0087] Select the automatic design method "linear layout method" or "broken line layout method", where:

[0088] (1) Linear layout method: This method means that the rock retaining wall is arranged in a straight line on the top view. The specific operation is as follows: Arbitrarily select a point M as the reference point within the previously determined protection range. The program starts with the horizontal X direction as the starting direction and automatically searches at a preset step length. A straight line passing through the base point M and penetrating the protection boundary is made at every interval of the step angle θ until the search angle ≥ 360°. For example, the i-th straight line intersects the protection boundary ABCD at points EF. Judge whether the protection length L EF satisfies L EF > L min . If not, skip to the next straight line. If it is satisfied, equally divide the line segment EF at a fixed distance with the pile spacing S to obtain equally divided points a, b, c... etc., as shown in Figure 8. Then project the equally divided points onto the ground to obtain the ground projection points (i.e., the center points of the ground piles) a′, b′, c′... and obtain the three-dimensional coordinates of each projection point a′(x a , y a , z a ), a′(x a , y a , z a ), a′(x a , y a , z a )... etc., as Figure 9 . Calculate whether the scheme where the i-th straight line is located meets the design principles, that is, judge whether the calculated slopes i ab , i bc , i cd ... are within the allowable range of the slope [i min , i max , and then give the judgment result. If there are multiple schemes where the straight lines are located that meet the design requirements, the user can independently select a scheme.

[0089] where i ab ,i bc ,i cd ... The mathematical expression is:

[0090]

[0091]

[0092]

[0093] Zigzag layout method: This method means that the retaining wall is arranged in a zigzag form in the top view. The straight-line layout method is to search for a layout scheme that meets the conditions, while the zigzag layout method is to specify a layout scheme. The principle for judging whether the scheme meets the requirements is the same as that of the straight-line layout method. The difference is that if the requirements are not met, the reasons for not meeting the requirements are given, and the user adjusts the layout line according to the prompt. The program judges in real time whether the adjusted scheme meets the requirements as the user makes adjustments, and the whole process continues until the design requirements are met. The specific operation is as follows: For the zigzag layout scheme GHIJ, as Figure 10 ,it is equally divided at a fixed interval with the pile spacing S to obtain equally divided points a, b, c... etc., as Figure 10 ,and then the equally divided points are projected onto the ground to obtain the ground projection points (i.e., the center points of the ground piles) a′, b′, c′... and the three-dimensional coordinates of each projection point a′(x a ,y a ,z a ),b′(x b ,y b ,z b ),a′(x c ,y c ,z c )...,as Figure 11 。Calculate whether the scheme where the zigzag line is located meets the design principle, that is, judge whether the calculated gradients i ab ,i bc ,i cd ... are within the allowable gradient range [i min ,i max , and then give the judgment result and prompt the user to modify, and so on in a loop until the modified scheme meets the requirements.

[0094] 5. Calculate and generate the model

[0095] After determining the layout scheme, the three-dimensional coordinates of the top of the i-th anchor pile P i ,y i ,z i ) can be calculated according to the projection point i′(x i (xip , y ip , z ip ), select the models of the anchor piles and the slab between piles from the database to obtain data such as the pile width B, pile height H, pile length L, slab thickness k, etc.

[0096] Among them, the three-dimensional coordinates of the top of the i-th pile are P i The calculation formula is as follows:

[0097] x ip = x i

[0101] Taking the top coordinate of the pile as the origin, calculate and determine the coordinates P i1 ~ P i8 of each corner point of the pile (8 corner points of the cuboid). According to the top coordinates P i and P j of two adjacent piles, calculate and determine the coordinates Q ij1 ~ Q ij8 of each corner point of the slab between the two piles (8 corner points of the cuboid), generate a three-dimensional design drawing, such as Figure 12 , and at the same time, a two-dimensional design drawing can also be drawn.

[0112] The coordinates of each corner point Q ij1 ~Q ij8 between the i-th and j-th piles are calculated as follows (in clockwise order):

[0113] Q ij1 : x ij1 =x ip , y ij1 =y ip +0.5·H + k, z ij1 =z ip

[0114] Q ij2 : x ij2 =x jp , y ij2 =y jp +0.5·H + k, z ij2 =z jp

[0115] Qij3 : x ij3 = x jp , y ij3 = y jp + 0.5·H, z ij3 = z jp

[0116] Q ij4 : x ij4 = x ip , y ij4 = y ip - 0.5·H, z ij4 = z ip

[0117] Q ij5 : x ij5 = x ij1 , y ij5 = y ij1 , z ij5 = z ip - r 1 - r 2

[0119] Q ij7 : x ij7 = x ij3 , y ij7 = y ij3 , z ij7 = z jp - r 1 - r 2

[0120] Q ij8 : x ij8 = x ij4 , y ij8 = y ij4 , z ij8 = z ip - r 1 - r 2
