摘要
通过性能化防火设计对北京地铁四号线北京南站的相邻区间隧道消防排烟进行定量分析,结果表明,当列车发生一般规模的火灾时,与疏散人员同向运动的火灾烟气对人员的安全威胁并不大;但当发生较大规模的火灾时,与烟气流动同向的疏散人员将不能够保证安全。
Through the quantitative analysis to Beijing South Station adjacent metro tunnel＇s smoke extraction of metro Line 4 tender in Beijing, it is proved that when the smoke flowing direction is same with the passenger evacuating direction, the life safe of passenger is threatened a little by smoke when the subway train fire is common scale, but the life safe of passenger will not be ensured when the fire is comparatively large-scale.
