为了更好的规划人员疏散路线,组织有效疏散,减少人员伤亡,为火灾风险评估、性能化设计及人员疏散提供强大的技术支持,利用FDS+Evac和Pathfinder疏散软件对服装厂建筑内同一火灾场景下人员疏散进行了模拟,有效地避免了由于单一软件造成的片面性,同时比较2种软件存在的差异.结果表明,使用FDS+Evac软件模拟,撤出楼层所用的时间约为104 s,而使用Pathfinder模拟,撤出楼层所用的时间约为95 s,FDS+Evac考虑了就近原则,人员一般会考虑在离自己较近的出口撤出,但并没有考虑人员的反应时间及心理因素.在Pathfinder模拟中分析了个体行为,与现实情况比较相符,但不能选择最优出口,经分析得出:在服装厂火灾疏散模拟中,Pathfinder与现实更接近.
In order to better plan evacuation routes, organize effective evacuation, reduce casualties, provide strong technical support for fire risk assessment, performance design and personnel evacuation, use the FDS + Evac and Pathfinder evacuation software to simulate the same fire scene in the garment factory building The evacuation of personnel was simulated to effectively avoid the one-sidedness caused by a single piece of software and to compare the differences between the two kinds of software.The results show that the time taken to evacuate the floor is about 104 seconds using FDS + Evac software simulation, Pathfinder simulation, evacuation time is about 95s, FDS + Evac considered the principle of proximity, personnel generally consider withdrawing from their own exit, but did not take into account the reaction time and psychological factors staff.In the Pathfinder The simulation analyzes individual behavior, which is in line with the actual situation, but can not choose the optimal exit. The analysis shows that Pathfinder is closer to reality in the simulation of fire evacuation in the garment factory.
