摘　　要：为提升沙河滩车辆段列车出段效率,满足后续增车需求,对列车出段能力进行分析与测算。首先列举出影响列车出段能力的3个关键要素,然后对这3个要素的影响方式进行分析,并测算全自动运行模式下的列车出段效率,最后对进一步提高列车出段能力提出两点建议。一是提升列车在咽喉区内行车速度,出段能力可提升到11.64列/小时,二是对信号系统设备升级,进一步缩短列车唤醒和自检时长。In order to improve the train departure efficiency of Shahetan Depot and meet the demand for additional trains,this paper conducts analysis and calculation on the train departure capacity.Firstly,it lists three key factors that affect the train departure capacity,and then analyzes how these three factors exert influence.Secondly,it calculates the train departure efficiency under the FAO mode.Finally,it provides two suggestions to further improve the train departure capacity.The first is to increase the train running speed in the throat area,so that the train departure capacity can be increased to 11.64 trains per hour.The second is to upgrade the signaling system equipment,so that the train dormancy and awakening time can be further shortened.
