目的通过对火灾场景下地铁车站内人员疏散情况的仿真分析,可为国家城市轨道交通疏散设计与预案制定提供指导。方法结合上海市某地铁车站远期(2037年)预测客流量,利用Smartfire和BuildingExodus软件对火灾场景下地铁车站内人员疏散情况进行了仿真模拟。结果当一部自动扶梯关闭,同时采用工作人员合理引导等手段对人群的疏散路线进行人工干预时,疏散时间可满足规范规定的6 min要求。结论工作人员的合理疏导可使各个出入口的利用率较均匀,从而节约人群宝贵的逃生时间,有效防止发生重大人员伤亡事故。
Aim Through the simulation analysis of the evacuation of subway station in fire scene, it can provide guidance for the design and plan of evacuation of national urban rail transit. Methods According to the predicted traffic of a subway station in Shanghai (2037), the evacuation of personnel in the subway station under fire scenario was simulated by using Smartfire and BuildingExodus software. Results When an escalator is closed and the staff is properly guided to intervene in evacuation routes of the population, the evacuation time can meet the requirements of the 6-minute regulation. Conclusion Reasonable counseling staff can make the utilization rate of each entrance more uniform, so as to save the crowd valuable escape time effectively prevent the occurrence of major casualties.
