摘　　要：大朝山水电站碾压混凝土掺合料采用新型 PT掺合料 ;拦河坝为全断面碾压混凝土 ,河床坝段的碾压混凝土采用斜层平推铺筑法施工 ;大坝上游为全断面碾压混凝土双曲拱围堰 ,下游为碾压混凝土护面的土石过水围堰 ;溢流坝面为碾压混凝土台阶式溢流面 .其中拱围堰和土石过水围堰已经过三个汛期的过流考验 .现场的各种检测资料证明 ,大坝碾压混凝土质量优良 .大朝山水电站的实践证明 。In Dachaoshan Hydropower Station ,the new PT admixtures are used. The dam is RCC dam. The pouring layers are slanting in the RCC construction of river bed dam section. It is RCC double-curvature cofferdam in the upstream of dam ,and the cofferdam in downstream is earth and rock overflow cofferdam. The spillway face are RCC benched spillway face. These cofferdams were tested for three flood seasons. It is proved from inspecting data that the RCC is of high quality. It is shown from the application of Dachaoshan Hydropower Station Dam RCC that the RCC could be widely applied in water project construction .
