【摘要】：针对高速列车火灾逃生通道狭小的特点,首先利用Pyrosim仿真软件结合真实燃烧试验所得的材料参数,进行了列车的火灾仿真。通过火势扩散程度、温度、热流量和烟层高度变化,确定了火灾状况下列车内乘客的极限逃生时间。然后通过人群疏散演练试验,并用Pathfinder软件对疏散情况仿真建模,确定了人群实际的疏散逃生时间。在列车中部起火后,引导疏散方案与自由疏散方案均能满足仿真所得的极限逃生时间要求,但引导疏散方案的效率更高。通过对整列列车的轨道面疏散仿真发现,若配有逃生梯的车厢起火,应及时将逃生梯转移,以大幅提高疏散效率。
[Abstract]:Aiming at the narrow fire escape passage of high-speed train, the fire simulation of high-speed train is carried out by using Pyrosim simulation software combined with the material parameters obtained from the real combustion test. The limit escape time of passengers in the train was determined by the variation of fire diffusion degree, temperature, heat flow rate and smoke height. Then through the crowd evacuation drill test and the Pathfinder software to simulate the evacuation model, the actual evacuation time of the crowd is determined. After the fire in the middle of the train, both the pilot evacuation scheme and the free evacuation scheme can meet the limit escape time requirements obtained by simulation, but the guided evacuation scheme is more efficient. By simulating the evacuation of the track surface of the whole train, it is found that if the compartment equipped with escape ladder catches fire, the escape ladder should be transferred in time in order to greatly improve the evacuation efficiency.
