火灾时期走廊内安全疏散研究

Research on safety evacuation in corridor of fire period

为了更准确计算火灾时期建筑物内人员疏散所需时间的问题,以疏散波理论为基础,分析了走廊中走廊与各房间汇合点的疏散状态,得出了汇合点不发生堵塞现象和发生堵塞现象的条件,并认为在进行疏散时间计算时,应对走廊中每个汇合点进行计算,考虑疏散时的堵塞现象,而不应用固定的疏散速度进行疏散时间计算。

In order to calculate evacuation time in building in fire period more exactly, based on the rarefaction wave theory, the author analyzes the evacuation states of the convergence point of the corridor and all apartments, gets conditions of blocking phenomenon, and determines that in the calculation of the evacuation time it should gets calculation on all convergence points in the corridor, think about the blocking phenomenon in the evacuation, hut can not calculate the evacuation time with fixed evacuation speed.
