城市铁路隧道防灾疏散及消防方案

Disaster Prevention and Fire Control Schemes for Evacuating People from Urban Railway Tunnel

研究目的:针对城市铁路隧道的特点,进行火灾时的消防及逃生分析,本文主要就单洞双线隧道提出几种防灾疏散逃生方案及主要消防设施的布置原则,供今后城市铁路隧道消防设计参考。研究结论:平行设置专用疏散通道、垂直主隧道设置紧急出口或在隧道中部设置救援站,是常用的几种防灾疏散方案;隧道宜结合竖井设置纵向排烟;隧道内外均应考虑消防给水水源及设备。

Research purposes：According to the characteristics of the urban railway tunnel,this paper makes analyses of evacuating people and fire control when there is fire,and puts forward some schemes for evacuating people and the main principle for arranging the fire fighting devices for the purpose of providing the reference to the fire control design for the urban railway tunnel.Research conclusions：This paper offers some commonly-used schemes for evacuating people.Namely,the special evacuation passage parallel with the main tunnel;the emergency exit along the main tunnel;rescue station in the middle of the tunnel.Longitudinal smoke emission model should be adopted with making full use of the shaft.The water supply for fire demand should be considered inside and outside the tunnel.
