摘要:
为提高地铁隧道火灾下人员应急疏散的安全性,对地铁区间隧道的疏散方式进行分析。基于武汉地铁实际工程,通过Pathfinder软件,对单洞单线、单洞双线及公铁两用单洞单线等3种隧道的疏散方式进行火灾应急疏散数值模拟后得到公铁两用单洞单线隧道疏散效率最高的结论。在此基础上对影响人员疏散的主要因素(疏散人数、疏散出口间距、疏散出口宽度、列车迫停位置等)进行模拟研究,以获得各影响因素与疏散时间、疏散速度的关系。研究表明:缩短疏散出口间距最有利于人员的疏散;只有在疏散出口位于列车长度范围的疏散平台内时,增大疏散出口宽度才能提高人员疏散效率;列车迫停区域距离疏散出口较近时疏散效率较高。

In order to improve the personnel evacuation safety in metro tunnel fire emergency. The evacuation modes of metro interval tunnel are analyzed. According to the actual project of Wuhan Metro, numerical simulation of fire emergency evacuation is carried out for evacuation modes of 3 types of tunnels that are single-hole single-track, single-hole double-track and highway-railway double-duty single-hole single-track tunnels. The results show that evacuation efficiency of highway-railway double-duty single-hole single-track tunnel is the highest. On this basis, the main factors affecting personnel evacuation are simulated and analyzed (number of evacuees, distance between evacuation exits, width of evacuation exit and forced stop position of train) to obtain the relationship between various influencing factors and evacuation time and evacuation speed. The research shows that shortening the spacing distance between evacuation exits is the best for personnel evacuation. Only when the exit is within the train length on the evacuation platform, increasing the width of evacuation exit can improve the evacuation efficiency. When the train forced stop area is close to the evacuation exit, the evacuation efficiency is higher.
