摘　　要：在人员聚集的大型建筑物中,一旦发生火灾,受困人员能否在安全疏散时间内撤离火区,最大限度地减少火灾人员伤亡,一直是建筑火灾应急救援研究领域急待解决的重大课题。以地下商业街为例,应用群集疏散行为模型,对人员疏散时间进行了理论分析和计算。通过火灾时期人员密度变化对人员安全疏散时间的影响分析研究,合理确定了地下商业街火灾风险控制人员密度临界值为0.7人/m2,其研究成果对大型建筑物中的人员疏散设计也具有一定的指导意义。In the large building where a lot of people get together,once a fire occurs,if people can escape from the building in the safety evacuation time is always an important topic of the emergency study.Taking an underground commercial street as example a human evacuation model was applied to calculate and analysis evacuation time in theory.By analyzing the influence of personal density on evacuation time during the period of building fire,it was determinzed reasonably that the critical personnel density value of the underground commercial street is 0.7 people per square meter.The research results have important significance to introduce the evacuation design in large building.
