摘　　要：研究了大空间建筑中仓室消防措施的有效性,按照规范设计的工况设计了全尺寸实验,研究了机械排烟和水喷淋对烟气层温度及高度的控制效果,并将结果与消防措施实效的情况下相比较,说明按照规范设计的消防措施能够有效的控制火灾,在规范设计基础上增大风机排烟量和水喷淋压力,取得了更加良好的效果,达到了灭火的目的。The fire protection of compartments in atrium is analyzed. According to the criterion, when the compartments catch fire, the mechanical exhaust can control the height of the smoke layer, and water spray can reduce the temperature of the smoke layer, if the fire protections are invalidated, the fire of compartments will be dangerous. After increasing the flow of the mechanical exhaust and the pressure of the water spray, it proves to be more efficient, the fire protections can not only control the fire , but also can put out the fire.
