某商场优化防火门开向对人员疏散的影响

Influence of opening direction of fire door on people evacuation in an underground supermarket

结合某大型地下超市的建筑结构和人员分布,应用网络节点疏散模型模拟人员疏散情况,并根据防火分区布局和疏散楼梯布置情况对内部防火门的位置和开启方向进行优化设计。计算结果表明:防火分区间防火门的优化设计使各个防火分区的疏散时间和疏散楼梯的利用率相当,总体疏散速度加快,对整体人员疏散很有利。

Based on the building structure and people distribution in a large underground supermarket,using network evacuation model to simulate people evaluation,and according to allocation of fire compartment and evacuation stairs,optimization design was made about location of fire door and opening direction.The results showed that optimization design of fire door makes the utilization rate of every fire compartment proper and evacuation bottleneck can be avoided,which quickens the whole evacuation speed and is meaningful for people safety.
