天津地铁6号线一期工程地下区间停车线设计

Design of underground parking track of Tianjin metro line 6 phase Ⅰ project

由于城市土地资源日益紧缺,城市轨道交通车辆基地等大宗用地规划选址难度不断增加,越来越多车辆基地选址于城区边缘,使线路长度相应增加,导致运营行车组织、车辆运用及管理、故障救援及夜间维保作业组织等运营管理工作难度加大。天津地铁6号线一期工程于地下区间设置12列位停车线,通过介绍其功能定位、总体方案及实际运营效果,总结设计过程中存在的问题,并给出解决方案,为类似工程地下停车线设计提供参考。

Due to the increasing shortage of urban land resources,the difficulty of planning and locating largescale land use such as urban rail transit vehicle bases is increasing.More and more vehicle bases are located at the edge of urban areas,which increases the length of the track correspondingly,leading to the increasing challenges in operation and operation organization,vehicle operation and management,failure and emergency rescue and night maintenance operation organization,etc.and the operational management is becoming more diffi cult.In the fi rst phase of Tianjin metro line 6 project,12 parking tracks are set up in the underground section.Through introducing its function orientation,general scheme and actual operation effect,the problems existing in the design process are summarized and the solutions are given,which provides reference for the design of underground parking tracks of similar projects in the future.
