摘　　要：为了提高不同类型公寓火灾人员逃生虚拟演练的真实性和科学性。以北京市某高校学生公寓的房间及走廊建筑结构火灾为研究对象,基于火灾动态模拟软件(FDS),研究火源大小为2 MW火灾的发生发展过程及其烟气蔓延的动态过程规律,得到房间内危险临界时间,走廊内危险临界时间等参数。结合数值模拟结果,根据逃生时间与危险临界时间动态对比,判断逃生人员的危险程度,实现同一公寓模型火灾逃生虚拟演练表明,理智型并有类似经验的男性最容易逃生。In order to improve the authenticity and scientificity of the virtual drill for fire escapes in different types of apartments.Taking the student apartment building in Beijing as a case study,this paper studied the occurrence and development of fire with a size of 2 MW and the dynamic process of smoke spread based on fire dynamic simulation(FDS)software.Get the dangerous critical time in the room,dangerous critical time in the corridors and other parameters.According to the results of numerical simulation,ac-cording to the dynamic contrast between the escape time and the dangerous critical time,the dangerous degree of the escapeor is de-termined to realize the fire evacuation of the same apartment mod-el.The virtual exercise shows that the sensible and experienced men are the easiest to escape.The results provide a way of thinking for the coupling between virtual reality and numerical simulation of building fire.
