市域铁路段场布点对收发车效率的影响分析

The Effect on Receive and Depart Efficient by Suburban Railway’s depot distribution

市域铁路车辆段、停车场常设于线路起终点车站附近,但在工程实践中,受场坪面积、地质条件等多因素控制,线路起终点不一定具有布设段场的条件,则段场需布置在线路区间。通过对车辆段场在线路两端与区间多种组合布点型式,通过对压道时间、发车就位时间、发车空驶距离、收车时间、收车空驶距离五个量化指标分析,对列车运营初期在时间和空间上的运营效率进行分析比较,提出推荐意见,可为其他市域铁路段场布点方案研究提供参考。

depot or parking lot of suburban railway generally housed in beginning or ending. The depot distribution is affected by area^ address conditions etc. the beginning or ending are not always satisfying the condition, depot has to distributed in railroad section. Comparing one depot plus parking lines, one depot in middle, one depot plus one parking lot, then Analyzing running performance by count the time of track-bed compaction, departure time, departure distance, receive time, receive distance to different depot distribution. Integrating the merits and demerits of various indicators , propose the recommendable options.it has reference significance for depot distribution to suburban railway projects.
