The evacuation situation of metro station in fire and other emergency situations is analyzed based on the research background of certain transfer station in Dalian metro.Through the survey of the number, age, gender and other parameters, the evacuation models are established.The models consider the different cases of emergency evacuation of the crowd with the application of Pathfinder software.The time of all evacuation to a safe area and evacuation at different times in the process of personnel distribution are obtained.That evacuation process is not conducive to the crowd evacuation "level" is found through the evacuation model and simulation under different circumstances.The conclusions of the study can be used as a reference for similar metro systems.These results also can be used as a reference for formulation of emergency crowd, evacuation organization, related emergency management and other aspects.%以大连地铁某换乘站为研究背景,对地铁站在发生火灾等紧急事件人群的疏散情况进行了分析.通过对调查统计人群的数量、年龄、性别等参数,应用pathfinder软件,建立地铁换乘车站人员疏散模型,并对该站在不同情况下发生紧急事件的人群疏散进行了研究.通过疏散模型,模拟不同情况下全部人员疏散至安全区域的时间,获取疏散过程中不同时刻的人员分布规律,找到疏散过程中不利于人群疏散的"关卡".文章结论可为国内外地铁换乘通道设计、紧急情况下的人群疏散组织及应急管理等方面提供一定的指导意义.
