| Abstract: | Xiluodu arch dam is a high concrete dam in the southwest of China.Comparison of the mode shape and natural frequency of the dam foundation system under different water levels and different foundation simplified models is analyzed with linear elastic finite element method.The seismic response caused by different combinations of earthquake records under different water level are computed with time history method.Estimation of numerical results and discussion of high arch dam analysis are performed in this paper. |
