地铁区间火灾工况下疏散指示联动方案的对比分析

Comparative Analysis of Evacuation Instruction Linkage Scheme Under Fire Condition in Metro Interval

地铁区间环境复杂、空间狭窄,一旦发生火灾,极易造成群死群伤的严重后果。为了快速、准确地联动区间疏散指示设备,同时配合隧道风机的排烟,对比研究了地铁区间火灾工况下的疏散指示联动方案。介绍了3种类型区间疏散指示设备,以及火灾报警系统与综合监控系统的两种关系,进行了区间火灾时乘客疏散流程及疏散方向分析。经过对比研究火灾报警系统与综合监控系统不同关系下的区间火灾工况下的疏散指示联动方案,推荐了最优的的区间疏散指示联动方案。

Metro interval environment is complicated and narrow.Once fire occurs,serious consequences of mass death and mass injury are of high possibility.In order to quickly and accurately coordinate the interval evacuation indicator system and cooperate with the smoke exhaust of the tunnel fan,the evacuation instruction linkage scheme under the fire condition in metro interval is comparatively studied.Three types of interval evacuation indicator system,and two types of relationship between FAS and ISCS are introduced,and the passenger evacuation process and evacuation direction analysis in case of interval fire occurrence is conducted.After comparatively studied the excavation instruction linkage scheme under different relationship between FAS and ISCS,the optimal interval excavation instruction linkage scheme is recommended.
