地铁列车火灾应急处置模拟

Simulation of Emergency Response of Subway Train Fire

使用PyroSim模拟列车突发火灾后不停车、区间停车自然排烟、区间停车机械排烟等情况下的烟气蔓延,使用Pathfinder模拟列车区间停车疏散。结合郑州地铁应急处置措施,综合分析各关键时间节点乘客所处环境的危险情况,对比乘客疏散所需时间及火灾时可用疏散时间,对列车突发火灾时的应急处置提出建议。

PyroSim is used to simulate the natural smoke exhaust after an emergency fire of the train without stopping,interval parking,and the mechanical smoke exhaust of the interval parking.Pathfinder is used to simulate the parking evacuation of the train interval.Based on the emergency response measures of Zhengzhou metro,this paper comprehensively analyzes the dangerous situation of passengers′environment at each critical time node,compares the evacuation time required by passengers and available evacuation time in the case of fire,and puts forward some suggestions for emergency response in the case of train fire.
