摘　　要：本文利用火灾动力学模拟软件(FDS)数值模拟了不同防火间距对工业建筑间火灾蔓延的影响,在此基础上,对比分析了烟气温度、热辐射和能见度等火灾参数的变化,得出了防火间距对火灾蔓延的影响规律,为工业建筑间的安全防火间距设计提供参考依据.In this paper,the effect of the different fire separations on the fire spread between industrial buildings was numerically simulated by fire dynamics simulator（ FDS） software. The variation of the fire parameters such as the flue gas temperature,the thermal radiation,and the visibility was comparatively analyzed on this basis. The law of the effect of the fire separation on the fire spread was concluded,which provides for the design of the safe fire separation between industrial buildings the reference basis.
