摘　　要：针对在运地铁线路行车能力不足的现象,分析了行车能力的计算模型。线路行车能力的薄弱环节在于折返站的行车能力。研究折返站的行车能力重点在于研究行车间隔。车站的配线方式决定了不同的折返方式。而不同折返方式可分解为不同的折返流程。所有流程中,行车间隔最大的环节决定了折返站的行车能力。详细分析了各种折返流程的行车间隔。结合广州地铁滘口站行车能力的优化方案,提出了提高折返站行车能力的措施,将滘口站折返时的行车间隔从126 s减小至120 s以内。Aiming at the phenomenon of insufficient running capacity of subway line, the calculation model of running capacity is analyzed. The weak link of the line traffic capacity lies in the traffic capacity of the turn-back station. The research on the traffic capacity of the turn-back station focuses on the study of the traffic interval. The wiring mode of the station determines the different turn-back modes, and the different turn-back modes can be decomposed into different turn-back flows. The link with the largest traffic interval in all flows determines the traffic capacity of the turn-back station. The traffic interval of various turn-back flows is analyzed in detail. According to the optimization plan of Guangzhou metro Jiaokou Station, some measures are put forward to improve the capacity of turn-back station, and the interval of Jiaokou Station is reduced from 126 s to less than 120 s.
