| Abstract: | According to the characteristics of the seepage prevention system of Pubugou earth-rock dam,FEM is applied to analyzing the seepage flow and the stress and strain of the whole dam.Then considering the construction of the joint area between the concrete cut-off walls and the core wall,sub-model method is adopted to further study the joint area;and better numerical results,which can be offered to the designer for optimizing the design of the dam,are achieved. |

| Keywords: | FEM sub-model method joint area stress and strain seepage prevention structure |
