Part of: Water Power '87


This paper summarizes the findings of an investigative report on roller-compacted concrete dams prepared by Morrison-Knudsen Engineers, Inc. (MKE) under contract to the Electric Power Research Institute (EPRI). The report, published by EPRI in September 1986, provides a broad overview of advances in concrete dam construction as a result of the development of roller-compacted concrete (RCC) technology within the last five years. Data regarding RCC dams completed or in various stages of planning or construction are presented. The technology is defined and compared to other dam construction methods. The project development process for an RCC dam is described, including design considerations, materials investigations and construction. Case studies for several RCC dam projects recently completed, under construction, or planned are presented. Costs of RCC dam construction are analyzed and compared to costs of construction of alternative dam types, including conventional concrete gravity, embankment and rockfill dams.
