市域快线安全线长度计算新方法

New Method of Safety Line Length Calculation for Suburban Express

通过分析城市轨道交通安全线设置的相关需求,结合市域快速轨道交通的特点,分析了影响安全线长度的主要因素,提出了安全线长度计算新方法,以解决安全线的有效长度对于具体线路缺乏针对性的问题。并以福州机场线大鹤站为例进行计算,计算得到安全线理论长度为55.00 m,比实际站场设置的安全线长度缩短1.64 m,验证了该计算方法的可行性。

Targeting the problem of effective length of safety line lacks specificity in each line,by analyzing relevant requirement of urban rail transit safety line setting,considering suburban rapid rail transit characteristics,the main factors influencing safety line are analyzed.Taking Dahe Station of Fuzhou Airport Line as an example,the theoretical length of safety line is calculated to be 55.00 m,which is 1.64 meters shorter than that of the actual station.The feasibility of the calculation method is verified.
