摘要
城市轨道交通线路多采用地下隧道的敷设方式,地下隧道的紧急疏散因人员众多、组织困难导致安全隐患。因此,对疏散梯进行合理布置,实现乘客的快速疏散,是必要的。基于Pathfinder疏散仿真软件,通过对市域C型车4编组列车疏散梯的10种布置方式进行仿真,对比分析乘客全部下车和离开列车位置的时间,进行疏散能力评价,得到更优的疏散梯布置方式。首尾车端部车门采用下沉式疏散梯、中间车中间车门采用折叠式疏散梯,全部下车需9.85min,离开列车位置需18.11min。
There are many problems in emergency evacuation,such as large number of personnel,organizational difficulties and hidden safety risks,for laying method of urban rail transit underground tunnel.It’s necessary to arrange the escape ladder rationally for rapid evacuation.Based on the Pathfinder software,ten kinds of the layouts of escape ladder are simulated on the 4 marshalling trains of C-trains of municipal railways.The time when all passengers get off the train and the time when they leave the train position are compared and analyzed.And the evacuation capability is evaluated in order to get the better layout of escape ladder.When sunken evacuation ladders are used for the end doors of front and rear trains and folding evacuation ladders are used for the middle doors of per intermediate train,it takes 9.85 minutes for passengers to get off the train and 18.11 minutes to leave the train position.
