摘　　要：以武汉某地下商城为研究对象,使用FDS模拟软件,在地下商城超市和商城通道分别设置着火点,通过对发生火灾时商城内各测点的温度场、烟气浓度场的分布进行数值模拟分析研究,得出两种着火位置下商城的烟气层高度、烟气层温度及CO2浓度的分布规律,并给出了相应的人员逃生措施。A physical model to Wuhan underground mall was taken as example, using FDS simulation software, setting ignition spot respectively in underground mall supermarkels and mall passage, the temperature of each nmasuring poinl and smoke coneentration field were analyzed by numerical simulation. The height and temperature of smoke layer, CO2 concen tration distribution law were oblained, and the corresponding measures for evacuation were Riven.
