| Abstract: | The seismic stability of earth-rock dam under seismic action is a comprehensive topic related to earthquake engineering,earthquake-resistant structure,rock mass mechanics and so on.Spectral element method is a special method of computation fluid mechanics,which combine finite element method with spectral method,and it possess both the flexibility of finite element method and the property of fast convergence of spectral method,and memory requirement and CPU time are reduced obviously at the same time. |
