地铁是人流比较集中的地方,而它与外界的联系主要为出入口,人员密集,排热排烟困难,发生火灾时与地面建筑或其它地下建筑火灾相比有它特殊的性质,所以地铁发生火灾时的人员疏散是一个非常重要的课题,本文通过对某明挖两层岛式地铁站发生火灾进行模拟分析,探讨了地铁火灾时的人员疏散问题。 Subway is a place where people are more concentrated, and its main connection with the outside world is entrances and exits. It is crowded with people and it is difficult to exhaust heat and smoke. In the event of a fire, it has a special character compared with ground buildings or other underground fires. When the evacuation of personnel is a very important issue, this paper simulates and analyzes the occurrence of fire in a subway station with two open-cut tunnels, and explores the evacuation of personnel in subway fire.
