摘　　要： 以某高校男生宿舍楼为载体,研究发生火灾时宿舍楼内人员的应急疏散情况。利用PyroSim和Pathfinder软件分别建立宿舍楼的火灾模型和疏散模型。通过PyroSim分析烟气层高度、烟气温度和能见度对疏散到一层楼梯口人员的影响。通过Pathfinder模拟发现宿舍楼人员疏散时间为414.8s,且当因火灾在一层楼梯口使人员处于危险境地时,还有大量人员没有疏散到楼外。提出增加外挂楼梯子的改进措施,得出最优的应急疏散方案,疏散时间减少1min。 Take a male dormitory building in college as an example,emergency evacuation of people in the building was studied.Pyrosim and Pathfinder were used to build the dormitory building fire model and evacuation model respectively.The impact on evacuation to the first layer was analyzed by calculating smoke layer height,the flue gas temperature and visibility of evacuation through Pyrosim.The dormitory building evacuation time was 414.8 s by Pathfinder simulation,and a lot of staffs couldn＇t evacuate outside the building when the fire was on the first floor stairway.Evacuation improvement measure as increasing outside hanging the stairs was put forward,which was concluded that the optimal emergency evacuation plan and evacuation time was reduced by 1 min.
