天津轨道线网车辆基地资源共享方案研究

研究目的:根据天津快速轨道交通线网规划,针对天津城市基础设施建设发展较快,用地日趋紧张的特点,在满足各线正常运营要求的前提下,通过路网资源共享优化车辆段的规模、合理设置联络线,以控制轨道交通用地,节省地铁工程投资。研究方法:结合轨道线网中九条地铁线路修建的先后顺序、厂、架修车辆段的设置条件以及各线路的功能及形态、地铁系统车辆选型的一致性、模块化和可继承性,进行综合技术分析比较,采用厂、架修任务量分析计算,方案对比的研究方法。研究结果:针对国内城市快速轨道交通建设的快速发展,研究探索出一套车辆综合基地资源共享的建设模式和一系列有指导性的技术措施。研究结论:天津市快速轨道交通线网内共设置2处厂架修车辆段,一处设4台位厂、架修段,另一处设2台位厂、架修段,共计6台位,满足线网内规划线路车辆厂、架修的需要,以及与之配套的4处线间联络线。

Program Research on Resource Sharing for Rolling Stock Base of Tianjin Rail Transit Network

Research purposes: In accordance with the rail rapid transit network plan of Tianjin and the characteristics of fast development of urban infrastructure construction and shortage of land for usage,the research is made on optimizing the scale of rolling stock depot and layout of connecting line rationally through network resource sharing on premise of meeting the requirements of normal operation for each line,in order to control usage of land for rail transit and reduce investment in Metro project.Research methods:With consideration of the construction sequence of nine metro lines in network,conditions of layout of depot for shop and un-wheeling repair,function and pattern of each line,and consistency,modularization and(hereditability) of type selection of rolling stock of Metro,the integrally technical comparison is made by adopting methods of program comparison,analysis and calculation of amount of work of shop and un-wheeling repair.Research results:A set of construction modes for resource sharing by the integral rolling stock base and a series of(instructional) technical measures are offered through making research according to the situation of fast development of rail transit in China.Research conclusions:Two depots for shop and un-wheeling repair rolling stock should be laid out for Tianjin rail(rapid) transit network,with 6 repair positions totally,including one depot with 4 positions and the other with 2 positions,so it can meet requirements of car running on the planned line in network for shop and un-wheeling repair network and requirements of 4 connecting lines forming a complete network.
