摘　　要：研究目的:为提高地铁终点站折返线的折返能力,文章以天津地铁6号线双港车辆段站的折返线方案为例,通过对天津地铁已建成和在建地铁终点站折返线的设置型式进行优缺点分析,经过技术方案比选和折返能力的计算,最终确定天津地铁6号线双港车辆段站折返线的设置型式。研究结论:终点站站后折返线的设置应根据规划地形条件,以工程难易程度、折返能力、运营灵活性、客运业务组织、运营灵活性、远期路网发展等因素为主要技术指标,进行综合经济技术比较,选择合理的折返方案。Research purposes： In order to increase the traffic capacity of turn-back track of the metro terminal station,this paper analyzes the merits and demerits of the layout patterns of the built and building turn-back tracks of the terminal stations of Tianjin metrol,compares the the plans,calculates the traffic capacity of the turn-back track and determines the layout pattern of the turn-back track of the terminal station at Shuanggang Vehicle Depot of Line 6 of Tianjin metro.Research conclusions：The turn-back track of terminal station should be laid out according to the terrain condition.The construction difficulty,the traffic capacity of the turn-back track,the traffic flexibility and the long-term development of urban rail transit network should be compared in technology and economy to choose a reasonable plan for the turn-back track.
