标准化城市轨道交通车辆段试车线长度设计

Design of Test Line Length for Standardized Urban Rail Transit Depot

随着国家对地铁统型工作的不断推进,配套资源的模块化、标准化规划设计方案有必要开展系统研究。试车线作为城市轨道交通车辆基地的必要配套工程,由于其位置及占地特点的特殊性,其长度将严重制约车辆基地的选址及布局。本文基于中国标准地铁技术参数,采用理论计算和项目经验应用,对城市轨道交通车辆基地试车线长度进行了量化计算,并对不同速度等级列车的车辆基地试车线长度进行了优先推荐说明,对具体工程设计起到一定的借鉴作用。

With the continuous promotion of the unified subway system,it is necessary to carry out systematic research on the modular and standardized planning and design scheme of supporting resources.As a necessary supporting project of urban rail transit vehicle base,the length of test line will seriously restrict the location and layout of vehicle base because of its special location and land occupation characteristics.Based on the technical parameters of China standard subway,this paper uses theoretical calculation and project experience to quantitatively calculate the length of the test line of the vehicle base of urban rail transit,and gives priority to the length of the test line of the vehicle base of trains with different speed grades,which can be used for reference in specific engineering design.
