基于轨道交通整体网络的市域铁路线路规划研究

A Study on the Suburban Railway Planning based on the Overall Network of Rail Transit

随着我国城市化进程不断推进,市域铁路发展需求不断增加,科学制定市域铁路线路规划,对推进新型城镇化市域铁路发展具有重要意义。在阐述市域铁路线路规划影响因素及结构模式选择的基础上,综合线路选择模型与线网规划模型的特点,建立市域铁路线路规划两阶段联合模型,先通过基于自身建设目标的线路规划模型中所得到较优备选线路集合,再联合基于轨道交通整体网络的线路比选模型的二次筛选,得出一个综合优化的市域铁路线路选择方案。以成德市域铁路线路规划为例,验证线路规划结果,为市域铁路线路规划研究提供借鉴。

With the continuous progress of urbanization in China,the demand for the development of the suburban railway is increasing.It is of great significance for promoting the suburban railway development of new-type urbanization to make a scientific formulation of suburban railway planning.based on expounding the influencing factors and structural mode selection of suburban railway planning,this paper comprehensively considers the characteristics of the line selection model and line network planning model.It establishes a two-stage joint model of city railway line planning.Firstly,the set of better alternative routes is obtained from the route planning model based on its construction objectives,and when combined with the secondary screening of the route comparison and selection model based on the overall rail transit network,a comprehensive optimization scheme of city railway route selection is obtained.Taking the railway line planning of Chengde as an example,the results of the line planning are verified,which can be used for reference for the study of the railway line planning of the city.
