Design of RCC Gravity Dam of Suofengyin Hydropower Station

After comparing dam types,the dam of Suofengyin Hydropower Station was determined to choose RCC gravity one.The dam with a highest of 115.8 m and a dam crest length of 164.58 m is made up with two block dam sections on the right and left banks and a spelling section on the river bed.The structure design and selection of concrete materials are favorable to quicken constructing and rolling on a big plane.Comparing with common concrete dam types,RCC dam has some features such as using less cement,simplifying measure of temperature control,shortening construction period,less cost and etc.
