摘　　要：针对现阶段地铁商铺设置中存在的问题,对站厅商铺是否增设排烟口进行讨论并量化分析,采用Pyrosim建模以及FDS软件对目标地铁站站厅商铺的火灾烟气特性进行数值模拟。分析发现,传统排烟模式不能很好控制烟气蔓延、保证人员安全,站厅商铺增设排烟口后,得出车站公共区烟气层厚度、温度以及CO体积分数的分布规律,满足人员安全疏散标准。For the existing problems of shops in subway, this pa- per discussed whether to add smoke exhaust port or not. At the same time, this paper established the model of target subway by Pyrosim and adopted numerical simulation to analyze fire sce- narios characteristics for shop in subway hall by FDS. Through the analysis, the traditional smoke exhaust design does not en- sure the safety of personnel. After adopting the design of adding shop exhaust ports, the variation tendency of the tem- perature, smoke of every area and CO concentration in subway were obtained, which accord with standards of personnel safety.
