Static and dynamic constitutive model of rockfill materials with its application in concrete panel rock-fill
dams", Doctoral degree thesis of Dalian University of Technology.
The types of the dams are concrete gravity, earthfill, concrete-face rock-fill
GEI will lead the design of the 6,400 acre-foot upper reservoir, a lined impoundment that will be formed by an earth- and rock-fill
dam with a maximum height of more than 200 feet and a crest length of 5,900 feet.
The dam was planned to be a concrete faced rock-fill
The earth and rock-fill
dam will be approximately 3,600 feet long and 650 feet high, which will make it the twelfth highest embankment dam in the world.
