摘　　要：出发追踪间隔时间是限制列车实现3 min追踪运行的主要瓶颈之一,压缩出发追踪间隔时间可有效提高线路通过能力.首先,分析高速列车出发追踪运行过程,提出在出站信号机内侧一定距离设置预发车信号机,使列车在出站信号机开放时具有一定初速度且剩余出站距离缩短;并设计预发车过程的“故障导向安全”原则以确保列车不冒进出站信号机;然后,在分析影响压缩出发追踪间隔时间因素的基础上,研究不同预发车方案下的列车控车模式曲线;最后,以上海虹桥站高速场为例进行仿真验证.研究表明:该方法能压缩列车出发追踪间隔时间,压缩效果随预发车距离的增大呈现先上升后下降的趋势;在到发线有效长可提供200 m预发车距离时,最大可压缩列车出发追踪间隔时间26 s以上.The departure tracking interval is one of the main bottlenecks that limit the 3-minute tracking operation of trains,and compressing the departure tracking interval can effectively improve line capacity.The departure tracking process of high-speed trains was first analyzed,and a pre-departure annunciator was set at a certain distance inside the outbound annunciator,making the train have a certain initial speed and shortening the remaining outbound distance when the outbound annunciator was open.At the same time,the principle of“failure-oriented safety”for the pre-departure process was put forward to ensure that the train did not cross the outbound annunciator.Then,based on the analysis of factors affecting the compression of departure tracking interval,the curves of train control mode under different pre-departure schemes were studied.Finally,the highspeed yard of Shanghai Hongqiao Station was studied,and the results show that the departure tracking interval can be compressed by the proposed method.The compression effect increases first and then decreases with the increase in the pre-departure distance,and the maximum compressible departure tracking interval can be more than 26 s if the pre-departure distance reaches 200 m of the effective lengths of the arrival-departure track.
