摘　　要：分析了烟气在大空间建筑内的充填情况 ,得到不同火源下的烟气填充计算模型 ,并在大空间实验厅内进行了全尺寸油池火对比试验。试验结果表明 ,烟气在大空间内的温度并不高 ,但烟气层下降速度很快。计算结果和试验结果对比表明 ,在大空间内仍可利用火灾区域模拟方法计算烟气的运动。对于油池火 。Analysis was made for smoke filling process in large space building, and some full-scale pool fire tests for comparison were made in USTC large space experimental hall of Univ. of Sci. and Technol. of China. The results show that the temperature rise of smoke layer is very low, but the descending of smoke layer is very quick. The zone model can still be used to simulate the smoke movement in large space. For the pool fire, the calculation model should be selected according to the heat release rate.
