摘　　要：地铁车站是人员密集场所,当发生突发事件时,需对人员进行及时安全疏散,地铁站出口作为重要的疏散设施,其疏散性能将直接影响应急疏散效率。以某地铁站为研究对象,根据人员安全疏散条件建立疏散时间模型并计算应急疏散时间,使用Pathfinder人员疏散软件模拟计算出站内人员疏散完成所需的时间,并与理论时间对比。结果表明,人员在规定时间内均可全部疏散且关于中心轴对称的两个出口疏散性能基本相同,并提出人员疏散优化措施,以为提高疏散效率提供依据。The subway station is a crowded place.In case of an emergency,it is necessary to evacuate people in a timely and safe manner.As an important evacuation facility,the exit of the subway station will directly affect the efficiency of emergency evacuation.Taking a subway station as the research object,the evacuation time model was established and the emergency evacuation time was calculated according to the safety evacuation conditions.The Pathfinder personnel evacuation software was used to simulate and calculate the time required for the evacuation of personnel out of the station.The results show that all the personnel can be evacuated within the specified time and the evacuation performance of the two exits with central axisymmetric is basically the same,and the optimization measures for personnel evacuation are put forward to provide basis for improving evacuation efficiency.
