摘要： 针对某城际铁路地下换乘站站厅1.2×104 m2 的超大防火分区，为确定合理有效的防火分隔方案，采用预先危险性的分析方法对站厅火灾风险进行了辨识，提出了“防火卷帘”“挡烟垂帘”“防火隔离带”3 种基于建筑消防安全性能的防火分隔方案。从合规性、人员安全疏散、火灾蔓延和烟气控制等方面对各方案进行定性分析，并总结优缺点。采用FDS 和Pathfinder 分别构建火灾烟气和人员疏散模型对各方案的消防安全性进行验证，结果表明3 种防火分隔方案均能满足人员的安全疏散。

Abstract: In order to make a reasonable and effective fire separation plan for the 1.2 × 104 m2 station hall fire compartment of an underground transfer station of intercity railway, fire risk of the hall was identified by the method of preliminary hazard analysis. Three different suggestions of using fire shutter, smoke curtain and firebarrier belt were proposed based on fire performance of the station.Advantages and disadvantages were summarized by analyzing compliances, safety evacuation, fire and smoke control of these fire separation schemes qualitatively. FDS and Pathfinder were used to build fire smoke and evacuation models to verify the fire safety of each scheme. The results showed that the three fire separation schemes can all meet the requirements of safe evacuation.
