Embodiment Construction

[0034] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings, but they do not constitute a limitation of the present invention, but are only examples; at the same time, the advantages of the present invention will become clearer and easier to understand through description.

[0035] The prerequisite for parallel design of two different design lines is that the left and right sides of the two lines have been designed with normal cross-sections, and road width, slope and gutter components have been installed respectively.

[0036] refer to Figure 1-7 Shown: a method for road parallel cross-section design, which includes the following steps;

[0037] ①. Select the main design line 1 and the secondary design line 2 that need to be designed concurrently;

[0038] ②. Set the parallel paragraphs for the main design line 1 and the secondary design line 2;

[0039] ③. According to the calculation of the line relat...

Abstract

The invention discloses a road parallel cross section design method. The method comprises the steps that (1) a primary design line (1) and a secondary design line (2) needing parallel design are selected; (2) segments needing to be parallel of the primary design line (1) and the secondary design line (2) are set; and (3) segmentation processing is performed on the primary design line (1) accordingto line position relation calculation of the primary design line (1) and the secondary design line (2), and each sub-segment primary line (1.1) and a corresponding sub-segment secondary line (2.1) are acquired. The method overcomes the defect that in the prior art, it is difficult to express side slopes and side ditches on a cross section precisely with a two-dimensional graph, and the method hasthe advantage of improving the accuracy of parallel design.

Description

technical field [0001] The invention relates to the field of road cross-section design, in particular to a method for road parallel cross-section design. Background technique [0002] In highway design, due to terrain, geological conditions or tunnel setting requirements, there are often two proposed highways that are relatively close to each other, such as the left and right halves of a separated subgrade, the ramp and the main line of an interchange. The cross-sections of the proposed highway often interfere with each other, so the slope, side ditch and drainage between them need to be designed comprehensively during the design process. [0003] Due to the irregularity of the horizontal distance and vertical height difference between the two proposed roads, the slope and gutter between the two roads are actually a three-dimensional surface entity in space, and it is difficult to use a unified mathematical model to accurately Express. Therefore, it is difficult to accurat...
