摘要
结合地铁内行人紧急疏散的交通特性,针对地铁火灾的危险性及其特点,利用性能化评估方法对地铁消防安全进行分析,再利用Legion软件模拟火灾情况下人员疏散,用安全疏散容量和人员疏散时间两个指标对地铁消防安全进行性能化评估。以某双层地铁站为例,设定火灾发生在列车上的场景,计算可知闸机容量最小,为地铁站的安全疏散容量。闸机应为地铁站消防安全设计的重点部位。
Based on the pedestrian traffic characteristics during e vacuation in metro, according to the risk of metro fire and its characteristic, the metro fire safety was analyzed by performance based assessment methods. After that, the Legion soft ware was used to simulate the pedestrian evacuation in fire. Two indexes were used to finish the metro fire safety assess ment,those are safe evacuation capacity and pedestrian evacua tion time. The scenario was set as fire in the train with the ex ample of double deck metro station. The calculation showed that minimum capacity of gates was the security evacuation capacity of the metro. The gate should be the key positions of the metro station fire safety design.
