摘　　要：在122.9 m高的试验塔上,采用定流量法,探究在特殊单立管系统的4层分别采用3种不同偏置管设置方法,开展了比对试验研究;同时,在偏置管处采用增加辅助通气管的形式,以期缓解立管轴线偏置对系统的影响。结果表明,偏置设置会改变系统的压力分布、降低系统的排水能力;增加辅助通气管会在一定程度上降低轴线偏置对系统的影响。A constant flow drainage system was used in a 34-layer tower. Three offset scenarios of the special single stack were investigated. The effects of assisted ventilation pipes, which were excepted to mitigate the impact of riser axes offset, were investigated as well. The results indicated that all offset scenarios decreased the drainage pipes reduced the impact of main capacity and changed the pressure distribution. The assisted ventilation stack offset to the drainage system.
