摘　　要：在超高层足尺试验塔上,设置两种不同高度的排水系统,分别采用定流量法与瞬间流量法,考察DN150铸铁伸顶通气系统内的压力分布情况,探究压力与流量之间的相关性,最终确定排水系统高度与通水能力之间的关系。结果表明,在定流量法中,超高层排水系统的排水能力小于小高层排水系统;在瞬间流量法中,超高层排水系统与小高层排水系统的排水能力基本相同。In a super high-level full-scale experimental tower, two sets of drainage systems of dif- ferent heights were set up and tested using the constant flow method and the instantaneous flow method, to explore the pressure distribution in DN150 cast iron pipes used in the drain-waste-vent （DWV） sys- tem, to investigate the correlation between pressures and flows, and to eventually determine the relation- ship between the height and the drainage capacity of a DWV system. It was concluded that, using the constant flow method, the drainage capacity of a high-level DWV system was lower than that of a low-lev- el DWV system; while, using the instantaneous flow method, the two systems exhibited similar drainage capacity.
