美国俄勒冈州的盖尔维勒坝位于南乌姆普夸河的支流考克里克河上,库容为5,200万m~3,工程任务是灌溉、供水和防洪,并装2台1,800kW的小机组发电。该工程坝高49m,原考虑采用土坝,后改为碾压混凝土坝,比土坝方案节省造价13%(为200万美元)。下游面坝坡度0.8∶1,使用无坍落度的碾压混凝土。为达到无坍落度,每立方米棍凝土的水泥用量只有52.8kg,粉煤灰含量为51kg。底部的浇筑层,在4m宽度
The Galville Valley, Oregon, is located on the Coxcreek River, a tributary of the South Umpquu River, with a storage capacity of 52 million m 3. The project is to provide irrigation, water supply and flood control and to install two 1,800 kW small units Power generation. The project dam height of 49m, the original consideration to the use of earth dams, later converted to RCC dam, than the dam program cost savings of 13% (2 million US dollars). Downstream dam slope 0.8: 1, the use of non-slump RCC. In order to achieve no slump, the amount of cement per cubic meter of concrete is only 52.8kg, fly ash content of 51kg. The bottom of the pouring layer, in 4m width
