Abstract:

Huangmugang Station of Shenzhen Metro line 14,existing line 7 and recently planned line 24 form a underground three line transfer station. The surrounding environment of the station is complex. The research priorities of this station is how to integrate various boundary conditions to form a scheme with perfect building function, economic and safe structure, and with the least impact on the surrounding environment, especially the research on station position and transfer function. During the scheme design process, by sorting out boundary conditions such as surface buildings, underground structures, surface traffic, area planning, engineering geological conditions, passenger flow prediction and station transfer function, the important and difficult points of Huangmugang Station, such as safety of overpass, traffic relief, pipeline modification, construction method, construction equipment selection, station position and transfer function are summarized. The method of breakthrough term by term is adopted to finally put forward the node transfer scheme of "dry" type, in which line 14 adopts the double side station with three floors underground to form parallel and same platform transfer with line 7, and forms platformplatform transfer with line 24.

Key words: metro station, design boundary conditions, station location selection, three line transfer scheme, scheme comparison
