建筑物火灾时期安全疏散模型

Safety evacuation model in building fire

为了更准确计算火灾时期建筑物内人员疏散所需时间的问题,提出了一种全新的计算方法,研究了火灾时期人员疏散的规律。由于建筑物密集人员疏散过程服从波传播规律,因此提出了疏散波概念,建立了疏散波数学模型,并介绍了疏散波数学模型意义。该模型对建筑物火灾时期楼梯间入口处安全疏散过程的研究及疏散设施的设置具有一定的理论指导意义。

To calculate the personnel evacuation time, a new calculated method is presented in this paper, and the rule of the personnel evacuation is researched as well. For the personnel evacuation process in building obedient the law of wave propagation, the evacuation wave is given out, and the mathematical model of evacuation wave was built too, the meaning of which is introduced as well. It has theory significance for the study on evacuation process at entrance of stairwell fire and the establishment for evacuation facility.
