地铁区间列车中部火灾人员疏散受烟气影响分析

Analysis on impact of fire smoke on personnel evacuation in the middle of metro train

为了研究地铁区间隧道内列车中部发生火灾时人员疏散受烟气的影响,以A型车为例,运用FDS软件模拟火灾烟气对乘客疏散的影响。研究结果表明,列车内部火灾烟气对人员的主要危害指标为温度,疏散平台处火灾烟气对人员的主要危害指标为可见度。

In order to study the impact of fire smoke on the evacuation of passengers when the fire occurs in the middle of the train in the subway tunnel,FDS software is used to simulate the influence of smoke on the evacuation of passengers.The results show that the main hazard risk index of fire smoke in the train is temperature,and the main hazard risk index of fire smoke in the evacuation platform is visibility.
