同站台换乘车站方案研究

对城市轨道交通中几种常见的同站台同方向换乘车站进行了分析比较。双岛4线换乘站只方便同站台同方向换乘的乘客,对反方向换乘的乘客很不方便。这种车站占地宽,施工对城市交通影响较大,工程造价高。单岛三层4线式车站可进行同站台同方向换乘,反方向换乘也很方便,通过调整线路组合还可进行同站台反方向换乘。这种车站使用方便,占地少工程造价低,应该进行推广。对一些为适应盾构法施工的变型车站方案,乘客使用不方便,工程造价高,应持慎重态度。

On Schemes for One-platform- interchange Station

With analysis and comparison of different one-platform-interchange stations,this paper argues that one-island-three-layer station has many advantages over double-island-interchange station in terms of passenger interchanging,land use and programme cost,etc.Considering the convenience for passengers and the cost of construction,the author holds that more caution shall be given to those modified stations which are constructed by shield method.
