Abstract

The invention discloses a longitudinal section line layout method and system, a terminal and a readable storage medium, and the method comprises the steps of obtaining the line information of a to-be-laid line, and constructing a longitudinal section line optimization model; obtaining a feasible region of station apron elevation search and a feasible region of line longitudinal section slope change point search based on the constraint conditions, and generating an initial layout result of a line longitudinal section, wherein the initial layout result is an initial value of a design variable; and based on the longitudinal section line optimization model, the feasible region of station apron elevation search, the feasible region of line longitudinal section slope change point search and the initial layout result of the line longitudinal section, optimizing by adopting an optimization algorithm to obtain a longitudinal section line layout result. According to the invention, the distribution of the gradient change points of the longitudinal section of the subway line and the collaborative optimization of the elevation of the station level are realized, and the coupling relation and dynamic characteristics of the gradient change points of the longitudinal section of the line and the elevation of the station level are considered, so that the scheme is more reasonable.

Description

technical field [0001] The invention belongs to the technical field of circuit design, and in particular relates to a longitudinal section circuit layout method, system, terminal and readable storage medium. Background technique [0002] The comprehensive cost of the subway is not only related to its operation plan and train control mode, but also the line design plays an important role, especially the longitudinal section design of the subway line. The design scheme of the longitudinal section of the line determines the station platform elevation and the layout of the slope change point, in which the station pad elevation determines the depth of the station and the construction method of the station, which in turn affects the construction cost of the subway; and the layout of the slope change point determines the slope of each slope section of the line and slope length, which determine the height of the train rising or falling, running time and running distance during the t...
