| Abstract: | The dynamic stability analysis of rock mass in high arch dam abutment is one of the main contents of anti-seism research of high arch dam. The theories and methods for dynamic stability analysis of rock mass in high arch dam abutment are systematically summarized in such aspects as the anti-seism standard, the criteria of stability evaluation, the structural and dynamic property of rock mass in dam abutment, as well as the limit equilibrium analysis method of rigid body, the discrete element method, the rigid body-spring element method, the lagrange discontinuous deformation analysis method, the numerical manifold method and the probability theory and method. The recent progress on the above aspects is also introduced. It can be shown that the theories and methods need to be investigated broader to meet the demand of dam construction practice. |
