摘　　要：水布垭水电站混凝土面板堆石坝坝高233m,采用强夯处理河床砂卵石覆盖层作为大坝基础,是200m以上级高坝第一例。强夯处理结果满足设计要求。强夯加固处理的试验、施工与检测,可为今后同类型堆石坝基础处理的设计与施工提供参考。The concrete faced rockfill dam of the Shuibuya Hydropower Station measuring 233 m in height, was constructed on the sand and gravel layers consolidated by foreed tamping. It is the first of dams over 200 m. The foreed ramping meets well the requirement of design. The testing, construction and inspection of the forced tamping operation on this project may be used as reference material for foundation treatment of projects of similar natures.
