摘要
某大型超市具有人员活动集中、火灾荷载密度较大以及疏散距离超长等特点,超出现有建筑防火规范要求,给判断是否安全带来不确定性。该文利用性能化设计方法研究了该超市在设定火灾条件下烟气填充以及人员疏散情况,并通过安全疏散时间判据来分析人员是否能够全部疏散。研究结果表明:在满足设定的火灾条件下,该超市的保护人员和财产的安全目标是可以达到的。
Evacuation is quite difficult for a large supermarket under a fire case because of large population, big fire density and long evacuation distance. The performance-based fire protection analysis was employed in this paper for a large supermarket. Smoke movement and human evacuation were investigated and the required safety egress time criterion was used for assessing whether the occupants could evacuate successfully. The human and property safety objectives can be reached under the conditions of design fires.
