摘要:
目的：终端折返站的折返能力是决定整条城市轨道交通线路运输能力的关键因素，因此有必要对既有线路终端折返站的折返能力进行研究，分析提升其折返能力的主要限制条件，优化运营组织模式。方法：以上海轨道交通1号线富锦路站为例，分析富锦路站的折返模式。首先，介绍了富锦路站站场，并定义了折返运行关键点；然后，计算了各关键点间列车的运行时间；接着，分析了富锦路站站前折返、站后折返和前后交替折返3种折返模式，并计算了3种折返模式下，各列车在不同关键点所需的折返时间；最后，对前后交替折返模式进行优化，人为延长列车在站后折返线的停车时间，将所有列车的接车间隔和发车间隔调整为相同时间间隔。结果及结论：单一的站前折返效率较低，列车折返时间间隔与中间站台停站时间线性相关；相比于单一的站前折返，单一站后折返的折返效率较高，列车折返间隔与列车折返线停留时间线性相关；前后交替折返模式中，站后折返列车的运行时间较为充裕，导致站后折返列车需要在折返线上停留较长的时间；优化后的前后交替折返时间间隔为110.28 s。

Objective: Terminal station turnback capacity is a critical factor determining the overall transportation capacity of urban rail transit lines. Therefore, it is necessary to study the turnback capacity of existing terminal stations, analyze the main factors limiting the turnback capacity, and optimize the operation organization mode. Method: Taking Shanghai Rail Transit Line 1 Fujin Road Station as an example, its turnback mode is analyzed. First, the station layout and key turnback points are introduced. The time interval between each key point is calculated. Then, the prestation turnback, poststation turnback and alternate turnback three modes are analyzed, the time interval data required at each key point of the above three is calculated. Finally, the alternate turnback mode is optimized by artificially extending the train dwell time on poststation turnback track, adjusting the arrival and departure intervals of all trains to the same duration. Result & Conclusion: The efficiency of single prestation turnback is relatively low, and the turnback time interval is linearly related to the dwell time at intermediate platforms on turnback track. Compared to single prestation turnback, single poststation turnback has higher turnback efficiency, while there exists the same linear correlation. In the alternate turnback mode, the running time for poststation turnback train is relatively ample, resulting in its longer dwell time on turnback track. The optimized interval for the alternate turnback mode is 110.28 seconds.
