3D Finite Element Analysis on a 270m Rockfill Dam Based on Duncan-Chang E-B Model
Finite Element Model (FEM) High CFRD Stress Strain
2011/12/21
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 constr...
