摘　　要：将防火隔离带应用到物流仓库中,以阻止货架之间火灾的蔓延。根据防火隔离带的理论模型,通过FDS模拟得到烟气层的最高温度,运用理论计算得到防火隔离带的宽度。结果表明,在设定的火灾场景下,货架之间需要设置7.9m宽的防火隔离带;在火源热释放速率确定的情况下,火源热辐射远大于烟气热辐射。火源对可燃物的直接热辐射是决定防火隔离带宽度的主要因素。The fire isolation belt is applied to the logistics warehouse, in order to prevent the spread of fire between the shelves. Based on the theoretical model of fire isolation beh, through the FDS simulation the highest temperature of the smoke layer was gotten, then the fire isolation beh width was calculated by the theory. The results showed that in the setting fire scene, the fire isolation heh width between the shelves is 7.9 m; when the heat release rate is determined, the fire ther real radiation is far greater than the smoke laycr thermal radiation. Direct fire radiation is a major factor in determining fire isolation belt width. Key words： logistics warehouse; fire isolation belt ; thermal radi ation; fire spread
