南京南站到发线运用方案对京沪高速铁路列车追踪间隔时间的影响分析

Impact Analysis of Arrival-departure Track Utilization in Nanjing South Railway Station on Train Tracing Interval Time of Beijing-Shanghai High-speed Railway

本文基于车站进路一次解锁及分段解锁的不同情况,重点研究了南京南站到发线运用方案对京沪高速铁路列车出发及到达追踪间隔时间的影响。在分析到发线运用方案对列车追踪间隔时间影响机理的基础上,对南京南站所有到发线运用方案下的列车追踪间隔时间进行检算。检算结果表明:到发线运用方案主要影响进路分段解锁下的南京南站列车到达追踪间隔时间,通过合理安排进路分段解锁情况下的到发线运用方案可压缩列车到达追踪间隔时间达40s。

Based on the principle of the one-time route and sectional route releases,this paper studied the impact of arrival-departure track utilization in Nanjing South Railway Station on train departure and arrival interval time of Beijing-Shanghai High-speed Railway.In addition,based on the analysis of the influence mechanism of arrival-departure track utilization on train tracing interval time,we studied the impact of arrival-departure track utilization on train tracing interval time.We calculated the train tracing interval time of all arrival-departure track utilization in this station.Our results show that train arrival interval time is the key limiting factor for shortening the train tracing interval time of Nanjing South Railway Station,and arrival-departure track utilization primarily affects the arrival interval time under sectional route release.Therefore,the arrival interval time of this station can be compressed up to 40 s by reasonably arranging the arrival-departure track utilization under sectional route release.
