摘要
城市轨道交通折返站的折返能力是决定线路运营效率的关键因素之一。介绍了尽端式站后折返线信号设备的布置原则。从最快解锁道岔和列车以最小距离停在折返信号机前的角度,对尽端式折返线设计长度及列车折返时间进行分析计算,得出在最高折返效率下的折返线理论长度,为工程建设提供理论依据。
The back-turning capacity of urban rail transit station is one of the most important factors to affect the operation efficiency.In this paper,the principle of turning-back line signal devices layout at dead-end station is introduced.Through analysis and calculation of the turning-back time and the design length of turning-back line based on the fastest unlock switch and the shortest train stopping distance,the theoretical length of turning-bake line is obtained,which has the highest turningback efficiency and could provide some theoretical support for other engineering projects.
