位于美国西北部俄勒冈州的威洛·克里克坝,是世界上第一座全碾压混凝土坝,主要用于防洪,兼顾灌溉和旅游。威洛·克里克坝是一座重力式溢流坝,最大坝高52米,坝顶长521米,坝体积为33.1万米~3。由于采用碾压混凝土筑坝方法施工,全部工程造价仅为1,400万美元,约为土石坝造价的55%,为混凝土坝造价的1/3。在进行威洛·克里克坝的设计和填筑试验时,设计人员考虑到要使铺筑层层间完全密实不透水,将增
Willow Crick Dam, located in the northwestern United States of Oregon, is the world’s first fully-meshed RCC dam and is mainly used for flood control as well as for irrigation and tourism. Willow Crick Dam is a gravity overflow dam, the maximum dam height of 52 meters, 521 meters long dam, the dam volume of 331,000 meters ~ 3. Due to the construction of roller compacted concrete dam construction, the entire project cost only 14 million US dollars, about 55% of the cost of earth-rockfill dam, concrete dam cost of 1/3. During the design and filling tests at Willough Creek Bar, designers considered that to make the pavements layers completely and impervious to water,
