As a kind of large volume underground vehicles, the subway greatly relieves the traffic pressure of the city. However, the main defect is a closed space can easily lead to high casualty once there is a fire. In this paper, Pathfinder software was utilized to simulate the evacuation in special subway station. The evacuation in dissimilar status was analyzed by setting up the fire scenario and changing the flow rate in the station. The results showed that the pressure of evacuation is mainly at stairway entrance and the width of exit has little effect on relieving the evacuation pressure. Besides, the number of the people in platform need to be restricted to 500 when the train is full; when the number of passengers in the train is 1542, that of people on the platform has to be limited to 480; when the number of passengers in the train is 1224, no more than 800 people on the platform need to be controlled.

地铁作为一种大型地下车辆，极大地缓解了城市的交通压力。但是，主要缺陷是，一旦发生火灾，封闭空间很容易导致高人员伤亡。本文利用Pathfinder软件模拟了特殊地铁站的疏散情况。通过设置火灾场景并更改站点的流量来分析处于不同状态的疏散情况。结果表明，疏散压力主要集中在楼梯入口处，出口宽度对疏散压力的影响不大。此外，火车满时，站台人数应限制在500人以内。当火车上的乘客人数为1542人时，站台上的人数必须限制为480；火车上的乘客人数是1224
