摘　　要：采用Fire Dynamic Simulation(FDS)场模拟软件模拟了高层建筑条形走廊四种不同工况下的火灾烟气温度。防烟空气幕的设置和排烟口的组合使用能够有效降低火灾烟气对人员安全疏散的造成的影响,其倾角的逐步增大能有效增强其防烟能力,并且能降低走廊内的烟气平均温度。改变防烟空气幕的初始速度对防烟效果改善不明显,考虑经济运行和实用性,可以在较小的出口初始风速情况下调整空气幕倾角以提高空气幕的防烟能力。[Abstract]Fire Dynamic Simulation （FDS）was applied to simulate the model of high-rise building aisle. Smoke temperature was analyzed under four different working conditions. The combination of air curtain and exhaust port in aisle can effectively reduce the influencing of safety evacuation due to fire smoke. And the ability of smoke-preventing can be enhanced and the average temperature of smoke in aisle can also be reduced with the increasing gradually of deviation angle of air curtain. The improvement of smoke-preventing effects was unclear with the change of initial velocity of air curtaln..Concerned about economical cost and practicality, ability of smoke-preventing can be improved by regulating deviation angle of air curtain, at relatively small air velocity through outlet.
