Interchange channel layout method and system for automatically changing and moving existing road along railway, terminal and readable storage medium

Abstract

The invention discloses an interchange channel layout method and system for automatically changing and moving an existing road along a railway, a terminal and a readable storage medium. The method comprises the following steps: S1, constructing an optimization model of a road and a railway interchange channel line; S2, performing unit grid division on the research area, and decomposing path search into two non-cross section search and cross section search; S3, performing path search on the two non-crossed sections and the crossed section based on the optimization model; and S4, splicing and integrating the N paths, the M paths and the P cross section local lines in the step S3 to form a plurality of complete lines, determining an optimal line by taking an optimization function as a target function, and performing curve fitting of a plane and a longitudinal section based on the optimal line to obtain a final line scheme. The method is decomposed into path search of non-crossing sections and crossing sections, coupling interaction of connecting points and crossing points is weakened, and road and railway interchange channel optimization is achieved.

Description

technical field [0001] The invention belongs to the technical field of railway design, and in particular relates to an overpass laying method, system, terminal and readable storage medium for automatically changing existing roads along railway lines. Background technique [0002] The railway is an important national infrastructure and the main artery of the national economy, and plays an important role in my country's economic and social development. In order to meet the needs of road transportation, the number of roads built and under construction has increased year by year, and the existing road network has become more dense. In the process of railway construction, there are a lot of intersections between existing roads and existing or new railway lines in many cities and regions, and are limited by the intersection angle, effective clearance and line shape of the intersections. In order to ensure that the existing roads In the case of limited time and energy, engineers o...

Problems solved by technology

The second stage: Propose an accurate solution, but the terrain changes and complex constraints are difficult to express with explicit functions, and there are theoretical deficiencies

The third stage: with the continuous innovation of optimization methods and the growth of computer computing power, a heuristic algorithm that does not depend on explicit functions is proposed. Among them, genetic algorithms are widely used in interchanges, but they are still limited to manual given An initial route plan, in the case of determining the start and end points of the route, optimize the route in the research area, and find a route plan that meets the constraints, which has certain limitations and is difficult to apply to the actual situation
