城市轨道交通高架车站站台型式研究

Research on Platform Types for Urban Rail Transit Elevated Station

城市轨道交通高架线路具有投资成本低、施工周期短、施工难度低、运营成本低、线路适应性良好等优点,高架车站站台型式选择由此也成为设计者非常关注的问题。从工程建设、车站功能、乘客使用等方面分析了岛式站台和侧式站台的优缺点,并分析了鱼腹式岛式车站的特点。在此基础上,分析了高架车站不同站台型式的适用条件,认为站台选型应以客流预测为基础。在满足远期客流及潮汐客流要求的前提下,车站站型依次推荐为侧式、鱼腹式岛式、普通岛式车站。

The elevated urban rail transit line has advantages of low investment,short construction period,low construction difficulty and operating cost,as well as good line adaptability.Therefore,the selection of platform type for elevated station has become the main concern of designers.Through analyzing the advantages and disadvantages of island platform,side platform and fish belly platform from aspects of engineering construction,station functions and passenger convenience,the applicable conditions of different platform types are discussed,and passenger flow prediction is considered as the basis for the selection of platform type.On the premise of satisfying long-term passenger flow and tidal passenger flow,the side type,fish belly type and standard island type stations are recommended in turn.
