城市轨道交通多层地下车站公共区排烟方案设计

随着城市轨道交通线网建设的发展,后建线路深埋将会加大,地下车站也将由原来常规的两层变为多层。车站深埋后对人员疏散和排烟系统提出了新的课题。在分析了地铁排烟系统设计与民用建筑的区别的基础上,研究提出了多层车站排烟系统设计及运行模式,包括站台、站厅及中间层的排烟系统方案及运行模式设计,可为同行提供参考。

Multi-storey underground rail transit station design smoke in public areas

With the development of the construction of urban rail transit network,the depth of subsequent-built metro line will increase,and the skeme of underground stations will transform from the usual 2-level into the multilayer.Deep buried design of the station raises new issues for the the evacuation and smoke exhaust system.On the basis of the analysis on the difference of smoke exhaust system between metro and civil building,the paper proposes a desgin scheme of ventilation and smoke exhaust system with the operation mode for the multi-layer station,including the sytems in the platform,concourse and mid-level respectively.The conclusion is expected to be useful for the peer reference.
