长大铁路隧道紧急救援站疏散设施设计参数研究

Study of Design Parameters of Evacuation Facility of Emergency Rescue Stations in Long Railway Tunnel

为了得到基于最少疏散时间和短暂聚集时间原则的铁路隧道紧急救援站疏散设施设计参数,采用building-EXODUS人员疏散仿真计算软件,考虑人员疏散的特点、速度及路径等因素,对不同横通道间距、横通道宽度和站台宽度等参数组合下的人员疏散时间进行计算。研究得到:1)紧急救援站疏散横通道的间距不大于60 m,宽度不小于3.5 m;2)17节车厢编组的普速列车紧急救援站站台的长度不小于500 m,站台高度不低于0.3 m,站台宽度不小于2.5 m。

The evacuation time in different combinations of parameters of spacing and width of evacuation passageway and width of platform is calculated by building-EXODUS simulation software considering characteristics, speed and path of evacuation, so as to improve the design parameters of evacuation facility of emergency rescue stations in long railway tunnel based on the principle of the minimum evacuation time and short gathering time. The study results show that： 1 ） The spacing of evacuation passageways should be smaller than 60 m, of which the width should be larger than 3.5 m. 2） The length of emergency rescue station platform of ordinary speed train with 17 carriages should be larger than 500 m, of which the height should higher than 0.3 m, and of which the width should larger than 2.5 m.
