摘　　要：高校图书馆由于人员密集、馆内藏书众多、设施材质易燃等特点,给火灾应急管理带来极大挑战。利用Revit构建图书馆BIM模型,运用Pyrosim软件建立FDS模型实现火灾场景模拟,分析火灾发生时各楼梯口处能见度、温度和CO浓度随时间的变化情况,得出各场景下疏散可用时间(ASET)。然后,运用Pathfinder软件建立Agent-based模型模拟图书馆火灾应急人员疏散,得出应急疏散必需时间(RSET)。最后,依据综合分析ASET与RSET的结果提出图书馆火灾疏散应急管理建议。Due to the characteristics of dense personnel,large collection of books and flammable facilities,college libraries face serious challenge of fire emergency management.Revit was used to build the BIM model of the library.To analyze the change of visibility,temperature and CO concentration with time at the landings when a fire occurs,and obtain the available safe egress time(ASET)in each scene,using Pyrosim to build FDS model to realize the simulation of fire scene.Then,In order to gain require safe egress time(RSET),the agent-based model was established by using Pathfinder to simulate the evacuation of library fire emergency personnel.Finally,according to the results of comprehensive analysis of ASET and RSET,some suggestions on emergency management of library fire evacuation were put forward.
