高铁站房大空间高架候车层消防设计

On the Design of a Spacious Framed Waiting Room of a High-speed Rail Station

以某高铁站房高架候车层为例,针对站房内高架候车层大空间结构设计不符合国家现行消防标准的情况,提出将"燃烧岛"、"防火舱"等概念用于大空间高架候车层消防设计的思路。通过多种火灾场景及疏散场景的设定,利用FDS模拟烟气蔓延、利用Pathfinder模拟人员疏散的方法验证了其消防设计方案的可行性,为"燃烧岛"、"防火舱"等概念用于大空间消防设计提供借鉴。

This paper raises the idea of the application of “fire - proof bulkhead” and “combustion island” in the design of elevated waiting room in a high - speed rail station against the unqualified design of this kind. The feasibil- ity of this design was tested by a variety of fire simulation scenes, the simulation of smoke spreading and modeling the evacuation and it offers some reference for the application of “fire - proof bulkhead” and “combustion island” in the design of a elevated waiting room in a high - speed rail station.
