对提高天津地铁双林站折返能力的研究

地铁是一种大容量、高效率的城市交通方式,而折返能力则是制约地铁通过能力的关键因素.分析天津地铁运营的具体情况,指出双林站折返能力的不足之处,提出3种改进方案;通过方案比选,选定"在双林站前增加一条渡线"的可行性措施,可以彻底改善该站的折返能力.结论:只有从硬件和软件两方面结合起来共同考虑,才能最大限度地提高列车的折返能力,充分发挥地铁的运输效能.

Study on Improving Turn-back Capacity of Shuanglin Station on Tianjin Metro

Metro is an effective urban traffic system and its turn-back capacity is a key factor which determines its whole carrying capacity. By analyzing the operation of Tianjin metro, this paper points out the insufficiency of turn-back capacity of Shuanglin Station and puts forward three schemes for improvement. In the end, a feasible scheme is accepted by comparing the proposed options, in line with which a crossover is added in front of Shuanglin Station in order to improve the turn-back capacity of the station completely.
