轨道交通试车线长度计算及正线试车设计要求

Length Calculation of Rail Transit Test Line and Test Design Requirements of Main line

试车线长度对轨道交通车辆基地用地规模控制起重要作用,也是车辆基地规划设计的关键点。通过对轨道交通试车线功能需求、列车牵引制动特性和关键控制因素等综合分析,提出试车线设置原则及长度计算等技术要求,为试车线的规划设计提供技术依据;对用地条件受限的车辆基地,提出降级设置试车线的具体方法,并结合工程实际案例对正线试车区段的选址、长度以及相关专业配套等设计要求进行了探讨。

The length of test line plays an important role in controlling the scale of vehicle base,and it is also the key point in vehicle base planning and design.Through the comprehensive analysis of function requirements of test line,train braking characteristics and key control factors,the principle of train test line and length calculation are proposed providing the technical basis for planning and design of test line.For the vehicle base with limited land resources,it gives the specific approach to degrade test line.Combined with an actual case,the location and length of test section of main line and engineering requirements of related supporting disciplines are discussed.
