摘要
研究了某大型商场建筑发生火灾时火灾现场的环境变化对疏散人群的影响,利用火灾烟气模拟软件Pyrosim 2014分析火灾时火场温度、CO气体浓度以及能见度的变化情况,给出人员安全疏散的最佳时间。利用人员紧急疏散模拟软件Pathfinder 2014分析了疏散人群安全疏散时间。提出将建筑火灾烟气蔓延过程的模拟结果与人员疏散过程的模拟结果进行对比分析,是火灾风险评估一种有效的方法,不仅能找出建筑物存在的消防问题,还可为建筑防火设计和消防整改提供依据。
This paper researched the influence of fire scene environment changes on evacuating people when a fire happens in a large complex building. The changes of fire scene temperature,CO gas concentration and visibility were simulated by using of fire smoke simulation software Pyrosim 2014,which gave the best time for people safety evacuation. The time of people safety evacuation was analyzed by using of urgent evacuation simulation software Pathfinder 2014. It is pointed out that the comparison and analysis of simulation results between fire smoke speading process and people evacuation process are an effective means of fire risk assessment,which can not only obtain the fire problems of buiding,but also provide the basis of fire protection design and fire rectification in a large complex building.
