摘　　要：在河床式厂房整体稳定计算中,基底扬压力是主要荷载之一。依托乌干达伊辛巴水电站项目,对河床式厂房整体稳定计算中的扬压力折减系数取值进行研究,比较了中美两国规范对于扬压力折减系数的取值规定。将扬压力设计计算值与渗压计的实测值进行了对比分析,探讨了扬压力折减系数设计取值中存在的问题,提出了新的计算方法,可以为类似工程提供参考。Uplift pressure along the base is one of the main loads in stability calculation of run-of-river powerhouse.The uplift pressure reduction factor in stability calculation of run-of-river powerhouse is studied based on Isimba Hydropower Station in Uganda.Provisions about uplift pressure reduction factor of Chinese codes and American codes are compared with each other.Design values of uplift pressure are compared with monitoring values.With that,existing problems in the design value of uplift pressure reduction factor and new calculation method are put forward,which can be referred by similar engineering.
