摘　　要：站前交叉渡线折返是目前城市轨道交通采用较多的一种折返形式,提高该类折返线能力对提高线路运能具有重要意义。文章分析了站前交叉渡线单股道和双股道折返的技术作业过程,通过列车牵引制动运行仿真,研究了进站速度和道岔限速2个关键因素对折返能力的影响,提出了提高折返能力的若干措施。该项研究可为城市轨道交通折返站设置提供依据。Scissors crossing in front of the station is a common turn-back form in urban mass transit so that improving the turn-back capacity is important for the line transport capacity. The process of turn-back on single track and double track are simulated during traction and braking operation and the influence of approaching speed and switch speed restriction are analyzed. Based on the analysis, some measures are suggested on improving the turn-back capacity as reference to construction of urban mass transport station.
