Stress And Deformation

Since no super high CFRD with dam height more than 233m been ever built in the world, more problems of 270m high CFRD are still to be explored and solved. The 270m extra high Maji CFRD is to be constructed. In order to get stress and deformation characteristic of this dam, 3D finite element analysis was carried out. To make comparison on stress and deformation of Shuibuya dam which has been built, the Duncan-Chang E-B model parameters of Shuibuya dam, which was obtained by large scale tri-axial experiment, was used here to prediction this 270m high dam behavior. According to the calculation results, some beneficial conclusions were obtained and the design scheme of the 270m dam will be optimized.
