成都市域快线穿越中心城区的线站位研究

Research on the Chengdu Suburban Railway Line and Station Location Passing Through City Center

随着经济的高速发展,城市化、区域化的进程加快,中心城区与周边地区的联系越来越密切,在这种发展形势下,介于城市地铁和干线铁路之间的市域轨道交通系统的出现可以很好地解决市域范围内中、长距离的出行需求。其服务半径大、运行速度快、服务水平高等特点,可加强中心城区各区域以及与外围组团间的快速联系。以成都市轨道交通13号线市域快线为例,在分析其线路特点、客流特点和速度目标特点的基础上,针对站间距和平面线形两个影响中心城区速度目标的因素,通过加减站分析、平面线形优化分析以及越行站分析,对穿越中心城区的市域快线线站位进行研究,总结穿越中心城区的市域快线线站位研究过程中应力求考虑的层面,确保方案合理可行。

With the rapid development of the economy,the process of urbanization and regionalization was speeding up,and the relationship between the central urban areas and the surrounding areas was getting closer.The appearance of the suburban railway system between the city subway and the trunk railway can solve the long-distance travel demand in the city area;its wide-ranging service,rapid running speed,and high service level can strengthen the link between the central urban areas and the surrounding areas.This paper is a case study of the Chengdu Metro Line 13 that analyzes the characteristics of its route,passenger flow,and speed target.Focusing on the two factors of station spacing and horizontal alignment affecting the speed target,this paper researches the suburban railway line and station location passing through the city center by analyzing addition and subtraction station,horizontal alignment,and crossing station.Thereafter,the paper summarizes the aspects that should be considered in research on this topic to ensure that the scheme is reasonable and feasible.
