| Abstract: | Three-dimensional elastic-plastic FEM method is adopted to calculate dam stress and distortion of Dongping arc dam before and after perforate, and equivalent stress calculation is performed. The result shows, the stress and distortion satisfies safety requirement. And on the basis of the whole dam emulation analysis, through performed, which is the reference of reinforcing. |
