摘　　要：在超高层足尺试验塔上,考察DN110 PVC-U专用通气排水系统隔层安装结合通气管工况下的气流分布情况,探究结合通气管设置方式对通气立管内风向以及结合通气管处风向、通气流量的影响情况。试验表明,在模拟超高层住宅排水系统中,隔层安装结合通气管工况下通气立管中同样会出现两处气流方向频繁反复的楼层区域,且随着排水流量的增加该区域的位置有逐渐向下移动的趋势;出现气流方向频繁反复的中部楼层区域的平均通气流量较附近其他楼层的平均通气流量更高;横支管最大正、负压均有偏向于正压的波动趋势。In a super high-level full-scale experiment tower, the DNllO PVC-U specific vent stack drainage system with the yoke vent installed at intervals was explored. The influence of the change of the setting of the yoke vent on the wind direction and the ventilation flow was investigated. showed that in the simulation of a high-level residential Experiments drainage system, the compartment installed with the yoke vent under the conditions of ventilation stack frequent direction changes appeared in two floor ar- eas, and with the increase in drainage, central area was higher than that in other towards the positive pressure fluctuation. the area moved downward. The average ventilation flow in the floors, and the Pmax and Pmin of the horizontal stack were shifted
