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 improve the reentry ability of the return line of the subway terminal, the article takes the return line of the double-deck depot of Tianjin Metro Line 6 as an example. Based on the setting of the return line of the completed and underway subway terminal of Tianjin Subway Station, Analysis of advantages and disadvantages, through the technical options and the ability to reincarnate the calculation, and ultimately determine the line of Tianjin Metro Line 6 Shuanggang depot return line set the type. Research conclusions: The setting of the return line after the terminal station should be based on planning topographic conditions, such as engineering difficulty, reentry capability, operational flexibility, passenger business organization, operational flexibility, forward road network development and other factors as the main technical indicators, Comprehensive economic and technological comparison, choose a reasonable return program.
