The invention discloses an automatic complicated mountain railway line trend generating method. The automatic complicated mountain railway line trend generating method includes the steps of S1, collecting information; S2, dividing the whole line selection research range into a plurality of grids, and adding the collected information as grid attribute; S3, performing bi-directional scanning on the grids; S4, according to the scanning result, updating the grid data including optimal connecting grid of the current grids and connection cost information from the current grids to an initial point; S5, adding distance graphs generated after bi-directional scanning, and generating the line trend according to the optimal connecting grid and the connection cost information from the current grids to the initial point in the distance graphs. The automatic complicated mountain railway line trend generation method has the advantages that the comprehensive cost such as engineering, operation and environment is regarded as objective function, the line-structure-environment coupling limits are considered, and automation degree and practicability are high.
Description
technical field [0001] The invention relates to a method for automatically generating the direction of railway lines in complex mountainous areas. Background technique [0002] With the implementation of the "Western Development" strategy, the construction area of my country's railways is changing from the eastern plains to the western mountainous areas. The "Twelfth Five-Year Plan for Western Development" proposes that during the "Twelfth Five-Year Plan" period, the western region will add 15,000 kilometers of railway operating mileage. All design units are faced with the heavy task of designing the western mountainous railway. The design of railway route selection is the core work of railway construction. In the complex mountainous area in the west, plane obstacles and elevation obstacles coexist, bridges, tunnels and other structures inevitably increase, there is a complex coupling constraint relationship between lines-structures-environment, and it is difficult to co...
