小型碾压混凝土坝的建造作为美国华盛顿州的综合利用工程修补项目的一部分,并增进了碾压混凝土坝在一些方面的应用知识。特别是,土基坝址所采用的碾压混凝土技术的适应性。在土基上必须采取控制渗流和水力坡降的措施以防止地基管涌,并且必须要按允许的基础沉降设计。锡达福尔斯(Cedar Facls)工程位于美国华盛顿州西雅图市东南方约64公里(40英里)的锡达河上。锡达福尔斯坝是为西雅图市居民和工业供水、发电和防洪的。该工程于1902—1904年动工兴建,主要是为抬高切斯特,莫斯湖的水位,当时建造了一座高4.88米(16英里)的填石(?)笼坝,1013年为了增加库容,又在距该坝下游2.4公里处建造了一座高70.12米
The construction of a small roller compacted concrete dam is part of a comprehensive utilization engineering repair project in the state of Washington in the United States and enhances the application of some aspects of RCC dams. In particular, the adaptability of RCC technology used in earth-based dam sites. Measures to control seepage and hydraulic ramps must be taken to prevent subduction on subsoil basis and the design must be subsided on an allowable basis. The Cedar Facls project is located on the Cedar River about 64 km (40 miles) southeast of Seattle, Washington. Cedars Falls is a city that provides water, electricity and flood control to Seattle city residents and industry. The project was started in 1902-1904, mainly to raise the water level in Chester and Moss Lake. At that time, a 4.88-meter (16-mile) rockfill dams had been built. In order to increase the storage capacity in 1013, , And a height of 70.12 meters was built 2.4 kilometers downstream of the dam
