| Abstract: |
| The numerical analysis of stress deformation behavior of the concrete diaphragm wall in a supper-deep overburdened layer of Yele Hydropower Station is carried out by using Duncan-Chang non-linear elastic model and two-yield surface elastic-plastic model.The influences of the numerical calculation model, the joint of the wall, the joint at the top of the wall, and calculating parameters of the residue at the bottom of the wall on the stress deformation behavior of the concrete diaphragm wall are analyzed. |
