摘要
研究建筑火灾疏散中人员早期行为及逃生过程中的行为规律,对于建筑火灾人员疏散模拟及安全逃生管理具有重要意义。通过对火灾中人员行为反应过程的分析,把影响人员行为的因素归纳为三个方面:建筑因素、火灾因素和人员因素。利用国内外试验数据,对人员在火灾中早期反应以及火灾对人员疏散行动速度的影响进行了量化分析。引入当量速度的概念,提出了人员在火灾影响作用下的逃生速度量化表达式。用当量速度实现疏散过程与火灾发展过程的结合,使人员疏散模拟更接近实际情况。
It＇ s important to study the characteristics of early reaction and the behavior rules of people for simulation and management of evacuation in buildings under fire.Three factors that affect human behavior in fire are concluded by analyzing the process of evacuation,namely,construction factor,fire factor and evacuee factor.A quantitative analysis on early human behavior and the impact of fire on move speed is performed by using test data.Equivalent speed is proposed to achieve the quantitative expression of the move speed when people are evacuated in a building under fire.By applying the equivalent speed in simulation of evacuation,the result of simulation will be closer to the practical situation.
