摘要
由于地铁隧道空间的密闭性,地铁隧道发生火灾时人员疏散困难,可能引发重大事故。文章通过建立地铁隧道火灾人员疏散模型,运用Pathfinder软件对不同的地铁隧道火灾疏散场景进行分析,确定完成疏散所需要的时间。根据仿真分析结果,对联络通道的宽度和间距进行优化,并利用仿真分析验证其有效性。
Because of the closure of subway tunnel space, pedestrian evacuation is difficult in subway tunnel fires and may causes major accidents. In this paper, based on evacuation model for subway tunnel fire, Pathfinder software is used to analyze different evacuation scenarios of subway tunnel fire and determine evacuation time. According to simulation results, the width and spacing of contacting channel are optimized, and effectiveness of the optimization results are verified by simulation analysis.
