摘要
火灾中人员疏散的开始时间是一个受多方面因素影响的随机量。现行的火灾数值模拟计算中常将它处理成一常量 ,显然与实际不符。该项研究采用统计理论的正态分布函数 ,建立了一个随机数学模型 ,研究火灾中人员疏散开始时间的范围 ,结合实例数据 。
When human behavior of evacuation in fires is concerned, the evacuation start time is a very important parameter. The evacuation start time, which is affected by many random variables, is a random variable. However, in most of the simulation of evacuation, it is regarded as a constant .It is obviously unreasonable. In this study, the evacuation start time is described by adopting normal distribution function and random variable model in order to describe the character of evacuation start time of man in fires. A common formula is given by fitting to experimental data to realize fix quantity study.
