| Abstract: | With respect to geologic problems of the Wanjiakouzi double-curvature arch dam,3D geomechanical model test is done to simulate the discontinuous rock mass of the dam foundation,mechanical properties of rock,foundation treatment and the whole dam.The impact of the foundation on structure deformation and stability of the dam is studied,and the whole process and mechanism of the dam and its abutments from the beginning of loading to the model＇s failure are displayed.As a result,the failure mechanism and the safety against overloading of the dam are learnt. |
