基于Matlab求解无配线曲线车站线路参数及设计方法研究

Study on Solving Line Parameters and Design Methods of Stations without Siding

随着我国城市化进程的高速发展,市域(郊)铁路作为一种大运量、快速化的交通体系,成为了解决中心城区与周边城镇交通拥堵问题的重要途径。本文通过分析无配线曲线车站的线路特征,推导出线路参数的几何关系方程组,利用Matlab及HRCAD的辅助设计程序,确定了线路参数的最优解,实现了夹直线段长度最短、工程投资最省的线路设计。研究成果可为市域(郊)铁路车站设计提供参考。

With the rapid development of urbanization in China,suburban railway,as a high-capacity rapid transit system,has become an important means for solving the traffic congestion problem in the central urban area and surrounding towns.In this paper,the author derives the geometric relation equation set of line parameters by analyzing the line characteristics of stations without siding curves,finds the optimal solution of line parameters by using the auxiliary design programs of Matlab and HRCAD,and on this basis,realizes the line design where the length of intermediate straight line segment is the shortest and the engineering investment is the lowest.The research results can provide reference for the design of suburban railway stations.
