高层建筑楼梯井直灌式送风加压研究

对直接向楼梯井内送风加压取代《高规》中规定的通过专用送风井向楼梯井内送风加压的可行性，在北京、上海、太原、都江堰等地的实际高层建筑中进行了试验验证，并在实测数据基础上进行了理论计算和CFD模拟分析，并分析了其经济性。结果表明，采用直灌式送风加压不仅可以满足《高规》中对压力值的要求，而且使楼梯井内上下压力更加均匀；同时也增加了使用面积，降低了工程造价。

Research on pressurization by direct blowing to stairwells for high-rise buildings

For validating the feasibility that direct blowing pressurization substitutes that with special air supply well specified on Code for Fire Protection Design of Tall Buildings, conducts experiments in actual highrise buildings in Beijing, Shanghai, Taiyuan and Dujiangyan. Based on the measured data, makes theoretical calculation and CFD simulation, and analyses the economic effects of this pressurization method. The results show that adopting this method can not only obtain the pressure required but also make stairwell pressure uniform, and moreover increase utilization area and reduce engineering costs.
