摘　　要：为研究地铁车站疏散能力,以国内某城市正在运营的岛式地铁车站为研究对象,采用数值模拟方法研究1列进站列车发生火灾时的人员安全疏散时间和人员密度,为地铁运营安全提供参考。研究结果表明:远期超高峰小时1列进站列车所载乘客及站台上的候车人员共1897人在5.4 min内全部撤离站台层到达站厅(安全区),同时站台公共区乘客人流密度最大值为0.67人/m2,符合地铁乘客疏散和安全运营要求。In order to analyze the evacuation capacity of a subway station,taking a subway station as the research object,the personnel safe evacuation time and personnel density of a subway station in case of fire are studied by numerical simulation method to provide reference for subway operation safety.The results show that:in the long-term super peak hours,a total of 1897 passengers including persons carried by an incoming train and waiting on the platform will leave the platform level and arrive at the station hall(safe area)within 5.4 minutes.Meanwhile,the maximum passenger flow density in the public area of the platform is 0.67 person/m2,which meets the requirements of passenger evacuation and safe operation.
