某体育馆防排烟及人员疏散方案优化研究

An optimizing study of smoke exhaustion and personnel evacuation in a gymnasium

大型体育馆类建筑设计中往往考虑到美观和使用功能等因素,使得诸如防火分区面积、疏散距离等消防设计远超我国现行消防规范要求,从而引发一系列诸如火灾蔓延特征改变、烟气扩散规律变更等问题。通过性能化方法对某体育馆进行消防设计评估,利用火灾模拟软件FDS模拟不同火灾场景,结合人员疏散软件pathfinder进行人员疏散分析,确定其排烟量、优化人员疏散方案,确保其能达到消防安全目标。

Considering the factors such as appearance and function in large gymnasiums＇ design, some fire- fighting designs like areas of fire compartments and evacuation distance go beyond the existing fire rules, causing a series of problems, such as the change of fire spreading characteristics, change of smoke move- ments and so on. At the same time, larger evacuation distance may lead to larger evacuation time. This pa- per evaluates the fire protecting system in a large gymnasium by using FDS and Pathfinder, and determines smoke exhaust rate, optimizes evacuation strategy, in order to achieve fire safety objectives.
