摘要
从哈尔滨市245家大型商场火灾荷载调查入手,分析并确定大型商场火灾荷载分布的数学模型,在此基础上研究影响大型商场可用安全疏散时间的火灾增长系数和燃料质量燃烧速率等不确定性参数的分布。利用火灾动力学和统计理论耦合的方法计算大型商场设定火灾场景下可用安全疏散时间的分布,结合工程实例分析某大型商场火灾下的可用安全疏散时间分布。
The fire load distribution mathematical model of mega shopping malls was figured out by studying on the fire load statistics of 245 mega shopping malls in Harbin. The distribution mathematical model of fire growth parameter and the mass combustion rate were also worked out by the fire load survey results. On this basis, the uncertainty analysis method of the available safety evacuation time(ASET) of mega shopping malls could be established and worked out by coupling fire dynamics and statistics theory. Finally, the uncertainty analysis method of ASET was advanced expounded by a real engineering case.
