某地铁火灾人员疏散分析

Analysis on people evacuation in a subway fire

采用人员疏散软件,模拟火灾工况下人员安全疏散所需要的时间。采用CFD技术分别模拟计算列车中部起火和头部起火两种情况下烟气层高度、温度及浓度的变化。在此基础上,根据人员安全疏散准则,对地铁人员疏散危险性进行分析,为地铁排烟系统的合理设计和人员疏散方案的制定提供参考依据。

Using people evacuation software,required safety evacuation time was simulated firstly.Then CFD was used to simulate height,temperature and concentration of smoke layer in the cases of fire happened separately at head and middle of train.And according to the rule of people safety evacuation,risk of people evacuation was analyzed,giving reference for appropriate design of smoke exhaust system and people evacuation plan.
