摘要
城际铁路隧道人流量大环境复杂,列车一旦在隧道内发生火灾,会造成重大的人员财产损失。为了研究单洞双向隧道内列车着火后人员疏散安全性,采用Pathfinder软件对着火列车停留在隧道内部的人员疏散规律进行分析,探讨此类隧道内的安全疏散设施布置以及人员疏散模式。结果表明:随着纵向楼梯宽度的增加人员疏散总时间不断减少,同时人员在纵向疏散楼梯口堵塞时间增加;随着纵向疏散楼梯口间距的增大,人员疏散所需总时间先减小后增大,疏散间距为70 m时,人员疏散时间最短。纵向疏散楼梯宽度和疏散楼梯口间距的优化,可为单线双向隧道内的疏散系统设计提供参考依据。
Intercity traffic involves a large flow of passengers and the railway tunnel environment is complex.Once a fire breaks out,it will cause major property damage and casualties.In this paper,Pathfinder software was used to analyze the rule of evacuation for people in railway tunnel after the train was on fire,and the layout of safe evacua-tion facilities and evacuation mode in tunnel under such evacuation mode were discussed.The results indicate that with the increase of the width of the longitudinal stairs,the total evacuation time decreases and the blocking time at the longitudinal exit increases.With the increase of the distance between longitudinal evacuation outlets,the total e-vacuation time first decreases and then increases,and when the evacuation distance is 70 m,the evacuation time is the shortest.
