摘要
突发地震危害巨大,往往伴随有火灾等次生灾害。火灾灾害发生后,合理组织人员撤离、有效减少拥挤踩踏事故、提高人们在应对灾害时的疏散效率尤为重要。利用Pathfinder疏散软件模拟了国内某办公楼人员在地震诱发火灾发生时的紧急疏散情况,并采用控制变量的方法对人员行为、人员速度、人员比例等不同参数设置下的疏散情景进行研究。结果发现人员速度和人员比例是影响人员疏散的主要因素,增加速度或者降低中老年人的比例会减少疏散时间,但增大速度或者改变人员比例到一定界限所带来的影响会慢慢减弱。提出了火灾延时疏散的策略,对优化人员逃生行径以及规范人员密集区域应急疏散管理具有很好的参考价值。
Sudden earthquakes pose enormous risks,often accompanied by secondary disasters such as fires.It is particularly important to reasonably organize the evacuation of people,effectively reduce congestion and stampede accidents,and improve the evacuation efficiency of people in response to the disaster when the fire disaster breaks out.The Pathfinder evacuation software was used to simulate the emergency evacuation of the personnel in an office building in China when an earthquake-induced fire occurred.The evacuation scenario under different parameter settings such as personnel behavior,personnel speed,and personnel proportion was studied by using the control variable method.The results indicate that the personnel speed and personnel proportion are the major factors affecting personnel evacuation.Increasing the personnel speed or reducing the proportion of the elderly will shorten the evacuation time,but increasing the personnel speed or changing the personnel proportion to a certain limit will gradually weaken the influence.The research put forward the delay evacuation strategy during fire disasters,which has a good reference value for optimizing the personnel escape behavior and standardizing the emergency evacuation management in densely populated areas.
