The gravity arch dam of the Sayano-Shushenskoe hydroelectric station has a construction height of 242.5 m, base width of 107.2 m, crest length of 1066 m, maximum head 220 m, and a volume of concrete of 8,500,000 m/sup 3/. This paper reviews the construction and materials technology involved in building the dam and the practice of staged start-up during construction at incomplete heads. The designers and builders were able to markedly reduce reinforcement of the dam without detriment to its reliability. It was also possible to almost completely eliminate imported rubble to make from gravel concrete all structural elements. Fly ash from a central heating and power plant was used as a binder in the final construction stages. Many aspects concerning possible improvement of the design of the dam, its economy, reliability, and improvement of the scheme of construction became clear during construction while conducting and analyzing on-site observations. These aspects are discussed in detail.
