摘要
借助火灾模拟软件Pyrosim,建立了全尺寸的隧道和列车模型,研究了车厢内尾部发生火灾工况下纵向排烟和半横向排烟方案的排烟效果:至火灾发生900s时,纵向排烟方案下人员疏散至隧道内车头位置后便处于安全区域,半横向排烟方案下人员疏散至火源左侧第一个排烟口或车头范围以外便处于安全区域;纵向排烟方案人员完全疏散出车厢可用安全疏散时间比半横向排烟方案多约370s,人员疏散至安全区域可用安全疏散时间比半横向排烟方案多约640s。
With the fire simulation software Pyrosim,a full-size tunnel and train model was established,and the smoke exhaust effect of longitudinal ventilation and semi-transverse ventilation schemes when fire broke out in the tail of the carriage were studied:When the fire occurred for 900 seconds,people evacuate to the front of the train in the tunnel will be safe under longitudinal ventilation scheme,and evacuate to the first exhaust outlet on the left of the fire or outside of the front will be safe under semi-transverse scheme.The available safety egress time for people to evacuate out of the carriage and evacuate to safety area under longitudinal ventilation is respectively 370 seconds and 640 seconds longer than the semi-transverse scheme.
