| Abstract: | Based on 3D nonlinear finite element method,the failure pattern and stability of 6# overflow section of Nabi RCC gravity dam is studied,and the failure pattern and the stability safety factor of the same are figured out through overload method.Moreover,multigrid method is used to search for dangerous slide block along potential slide paths in order to determine the most unfavorable slide path. |
