武汉地铁徐家棚换乘站设计方案研究

研究目的:武汉市轨道交通7号线是武汉远景规划网络中衔接西部新城组群、南部新城组群的一条重要的市域线路,7号线一期工程共设站18座,其中换乘站9座。徐家棚站为7号线长江以南靠江第一个站,该站位于和平大道和团结路交叉路口处,在线网规划中7号线徐家棚站与5号线、8号线换乘,因此徐家棚站为三线换乘车站,如何处理好三线的换乘关系、做好换乘节点的对接规划预留以及处理好与市政工程之间的关系是本文研究的重点及难点。研究结论:本研究根据三条线路的大致规划走向,结合站址周边环境条件提出徐家棚站换乘方式为三线"工"字形换乘,并将过江公路隧道这一市政工程与地铁车站结合起来统筹考虑工期设计、同期实施,减少不必要的重复建设,本文对于正在或者即将进行的三线换乘车站与市政工程的结合设计有一定参考价值。

Research on Design Plan for Xujiapeng Transfer Station of Wuhan Metro

Research purposes:The line 7 of Wuhan metro is an important line to connect the new west downtown with the new south downtown in long-range plan.The 18 stations,including 9 transfer stations will be built in the first phase project of the Line 7.The Xujiapeng Transfer Station is the first station close to the Yangtze River in the south,it is located in the cross between the Heping Avenue and Tuanjie Road and it will transfer with the Line 5 and the Line 8 of Wuhan metro.So this station will be a three-line transfer station.The researchs on how to deal with the transfer relation among the three lines,how to do the pre-remaining works in the joint plan for the transfer station and how to deal with the relation with the public works are the key and difficult points. Research conclusions:According to the planned alignments of these three lines and the environment conditions around the Xujiapeng Transfer Station,it is proposed the "工"shaped transfer mode should be adopted for the Xujiapeng Station.The river-crossing tunnel should be designed and constructed with the station at the same time to reduce the unnecessary repeated construction.The research presented in this paper can provide the reference to the similar works.
