摘要
以某地铁站为研究对象,通过火灾模拟软件FDS对假定火灾场景中的温度、能见度、热释放速率、燃烧速率随时间的变化情况进行定量分析,将GB 50157-2003《地铁设计规范》中规定的站台层事故疏散时间与人员疏散可利用时间进行对比,并提出消防安全设计建议。可以看出,目前《地铁设计规范》中关于站台层事故疏散时间"不大于6min"的规定过于笼统,适应性差,应尽快制定专门的地铁设计防火规范。
Taking a subway station as a study instance,fire simulation software FDS was applied to quantitatively analyze the temperature,visibility,heat release rate and burning rate changing with time in assumed fire scene.Evacuation time of platform layer in accident according to GB 50157-2003＂Code for design of metro＂ and evacuation available time calculated were compared and analyzed,and fire safety design suggestions were made.It can be seen that the provision that evacuation time of platform layer in accident being not more than 6 min in ＂Code for design of metro＂ is too general,and has poor adaptability.It was recommended that subway fire protection design specification should be developed as soon as possible.
