摘要
从《地铁设计规范》相关条文规定出发,探讨车辆基地出入线列车一度停车再起动的平纵断面关系;分析列车在停车时、停车后和起动时等三种不同工况的受力情况。根据牵引计算原理,建立其平纵断面关系模型。以长沙市轨道交通2号线西延二期工程为例,计算出入线的最大坡度与最小曲线半径。
From the view of some provisions in ＂M etro Design Code＂,the relationship between plane and vertical sections for metro train temporary stopping and re-starting on metro vehicle depot entering and exiting route are discussed,the force situation of three kinds of working condition,including the stopping,stopped and re-starting is analyzed. Then,according to the theory of traction calculation, a relationship model between the plane and vertical sections is established.Taking the west extension of Changsha metro Line 2 on the second phase for example,the maximum grade and the minimum curve radius on the entering and exiting route in metro vehicle depot are calculated.
