摘　　要：发生突发事件时,及时把地铁站内的人员疏散至安全区域是保障地铁公共安全的必要措施.阐述了人员疏散社会力模型的基本原理,分析了郑州地铁火车站的内部结构、出入口和客流分布情况,计算了人员疏散的时间.以社会力模型为基础,采用FDS+Evac软件对一列满载列车上的乘客及站台候车的乘客从站台层疏散至站厅层各出口的过程进行了模拟,比较了不同人群的疏散时间,分析了出口熟悉程度和出口宽度对疏散时间的影响.When emergency occurs,it is necessary to take measures to evacuate occupants in the metro station to safe areas in time in order to protect the safety of metro public. This article expounds the basic principle of the social force model of occupants evacua-tion,analyzes the internal structure,entrances and distribution of passengers flow of Zhengzhou metro railway station,calculates the e-vacuation time. Based on the social force model,using FDS+Evac software,the process of evacuating the passengers in a full train and in the platform from the platform layer to the exports of station was simulated,the evacuation time of different crowd was compared, and the influence of the familiarity and the width of the exports on the evacuation time were also analyzed.
