摘要 市域（郊）铁路停车线的设置对工程造价及后期运营有较大影响。各设计规范对停车线的设置间距要求不同，不利于市域（郊）铁路的规划及设计工作。本文首先对各设计规范中关于停车线设置间距的规定进行梳理分析，而后通过对轨道交通故障救援基本原则、流程及时间进行研究，得出影响停车线设置间距的关键参数，最后对市域（郊）铁路停车线的设置距离进行计算，提出停车线设置距离的推荐值。

Abstract The setting of suburban railway parking lines has a great impact on project cost and later operation. Different design specifications require different spacing of parking lines, which is not conducive to the planning and design of suburban railway. This paper first sorts out and analyzes the provisions on the spacing of parking lines in each design specification, and then obtains the key parameters affecting the spacing of parking lines by studying the basic principles, processes and time of rail transit fault rescue. Finally, the setting distance of urban ( suburban ) railway parking lines is calculated, and the recommended value of the setting distance of parking lines is proposed.
