基于Pathfinder的地下商场消防安全疏散模拟

The fire safety evacuation simulation of underground shopping mall based on Pathfinder

对Pathfinder人员疏散软件进行了简单介绍,根据工作中发现的地下商场人员疏散问题,结合实例针对防火卷帘两侧防火门正常和锁闭两种情况,综合考虑烟气运动和防火卷帘下降情况,运用Pathfinder软件进行模拟分析确定人员疏散时间。结果表明在防火门被锁闭情况下,人员疏散将可能导致发生严重问题。

This paper simply introduced the Pathfinder personnel evacuation software,according to the underground mall personnel evacuation problems found in the work,combining with the examples,according to fire door lock and normal two cases of both sides of fire shutter,comprehensively considering the smoke movement and fire shutter declining situation,application of Pathfinder software made simulation analysis to determine the evacuation time. The results showed that under the situation of fire doors were locked,the personnel evacuation likely to cause serious problems.
