The authors make several observations on the cracking of the Sayano-Shushenskoe Dam. First, they state that the dam was constructed of concrete with high thermal properties in blocks whose sizes considerably exceed the analogous parameters for hydraulic structures constructed elsewhere in the area. They state that solidity of the enlarged blocks was provided by traditional technological and technical measures not requiring considerable added expenditure. They conclude that by far the most cracks in the dam have been caused by the use of cantilever formwork which called for early striking of the concrete, and which have a negligible width and depth of penetration into the masses. They state that this cracking does not pose a danger to the structure and that therefore the use of the industrial cantilever formwork was justified. The authors conclude that through cracking in the first column of the dam, related to the presence of inspection galleries at the middle of its width, can be eliminated by locating the latter at a distance of not more than 0.2-0.25 of the column width from the column joint. Finally, they state seepage through the cracks is negligible.
