摘要
高校教学楼人员密集,火灾载荷大,是重点的消防安全管理场所。为研究该类建筑物的消防安全特性,联合使用火灾动态模拟软件Pyrosim和人员疏散模拟软件Pathfinder,开展了火灾蔓延和发展规律以及人员紧急疏散情况的数值模拟研究。建立模型对典型教学楼火灾及人员疏散情况进行全尺寸数值模拟分析。根据仿真实验所得结果和数据,分析了教学楼发生火灾不同时刻火势蔓延情况,烟气扩散情况,有毒气体浓度、温度分布和能见度的变化规律以及人员紧急疏散情况。研究结果可为类似建筑物消防安全设计提供参考性依据,有针对性地设定消防应急预案,对现场消防工作具有一定的指导作用。
University teaching building is the focus of the fire safety management with staff density fire load.In order to study the fire safety characteristics of this kind of buildings,the fire dynamic simulation software Pyrosim and the personnel evacuation simulation software Pathfinder were used to study the law of fire spread and development and the emergency evacuation.The model was established to simulate and analyze the fire and evacuation of typical teaching building by full size numerical simulation.According to the simulation results and data,the paper analyzes the fire spread,smoke diffusion,toxic gas concentration,temperature distribution and visibility change in different time of the fire in the teaching building,and the emergency evacuation situation.The results show that the model can effectively carry out the fire analysis of teaching building,which can provide the reference basis for the fire safety design of similar buildings,and has a certain guiding role in the fire emergency planning and on-site fire prevention.
