摘　　要：纵横方向跨度较大的现代大型商业建筑,难以完全依照传统的防火设计方法进行防火设计.根据现代大型商场的设计特点,提出将大型共享空间作为"亚安全区".采用计算机模拟的方法,从烟气流动和人员疏散两个方面进行量化分析,结果表明大型共享空间可以在较长时间内保持安全,可以视为人员疏散的"亚安全区",并为消防人员侦察扑救火灾提供暂时安全场所.设置"亚安全区"是解决大型商业建筑消防设计难题的一种有效思路.As the span of the length and width of large-scale modern mall become larger and larger,the fire safety design cannot be accorded with the traditional fire code completely.Based on the space characteristics of the large-scale modern mall,the authors bring forward that the large share space can be taken as a sub-safety zone to deal with the fire safety problem.The fire safety of the large share space is analyzed quantitatively from smoke movement and occupant evacuation by simulation method.The result shows that the large share space can keep safety in a long time,and can be regarded as a sub-safety zone for occupant evacuation and fire fighting.Utilizing large share space as a sub-safety zone is an available method to resolve the fire safety design difficult of large-scale mall.
