摘　　要：根据沈阳市地铁1号线部分典型站点建筑设计的相关数据,选择火灾常发生点建立物理模型,运用场模拟的方法,利用计算流体力学(CFD)的数值模拟软件STAR-CCM+对列车在典型车站的火灾进行了数值模拟,研究在一定通风速度下该换乘站火灾烟气的温度场、浓度场等蔓延规律。总结出地铁火灾发生时烟气流动的规律特点,并据此提出相应的人员安全疏散措施。According to the architectural design of part of the typical site data of the Metro Line 1 in Shenyang City, and se- lecting fire prone point to establish the physical model, the nu- merical simulation of typical transfer station fire was made with the use of numerical simulation software STAR- CCM of computational fluid dynamics （CFD）, through the application of field modeling method. The smoke spread rules and charac- teristics of temperature field and concentration field of the transfer station fire with certain ventilation rate were studied, which provide the measures for evacuation.
