轨道交通复线的适用性研究及启示

Applicability study and Enlightenment of Multiple Track

在轨道交通快慢车运输组织模式下,往往会存在运能与快速需求间的相互制约问题,而建设轨道复线能够有效疏解快线矛盾并大幅度提高廊道的运输能力。该文综合国内外轨道复线的规划建设经验,分析总结了三种轨道复线的设置形式、特点及适用线路特征,并对上海轨道交通发展提出相关启示。

Under the fast-and-slow train transportation organization of rail transit,there is often a problem of mutual constraint between transportation capacity and fast demand.However,the construction of multiple tracks can effectively alleviates that contradiction and greatly increases the transportation capacity of the passenger flow corridor.Combining with the planning and construction experience of the multiple tracks at home and abroad,the paper analyzes and summarizes the setting forms,characteristics,application and limitations of the multiple tracks,and puts forward relevant enlightenment for the development of Shanghai Rail Transit.
