摘　　要：为降低火灾风险,减少人员疏散所需时间,提高应急疏散效率,以山西某医院高层建筑为研究背景,运用火灾动态模拟软件Pyrosim和火灾动力学模拟工具(Fire Dynamics Simulator,FDS)建立高层建筑火灾数值模拟模型,分析烟气层高度、温度、能见度和CO浓度随时间的变化情况。然后利用Pathfinder人员疏散模拟模块建立人员应急疏散模型,计算人员所需的安全疏散时间,分析烟气层高度、温度、能见度及CO浓度对人员疏散的影响。最后,通过区域划分对人员疏散路径进行优化以减少安全疏散时间。In order to reduce the risk of fire,reduce the evacuation time and improve the efficiency of emergency evacuation,a numerical simulation model of high-rise building fire was established by writer’s team using Pyrosim and Fire Dynamics Simulator(FDS)to analyze the changes of smoke layer height,temperature,visibility and CO concentration with time in a hospital high-rise building in Shanxi Province.Then the Path finder evacuation simulation module is used to establish the emergency evacuation model,calculate the required safe evacuation time,and analyze the influence of smoke layer height,temperature,visibility and CO concentration on evacuation.Finally,the evacuation route is optimized by region division to reduce the safe evacuation time.
