| Abstract: | In this paper, the dynamic Property of the system of spillway dam-reservoir-foundation has been computed by finite elements(2-dimenslon and 3-dimension), and earthquake response of the spillway dam has been computed by both the response spectrum and time-history analysis. The results of analyses show that this type of spillway dam is favourable for improving it's earthquake resistant behavior, and both stability and stress state of the spillway dam can satisfy the requirements of national defence. Finally, the suggestion for improving dynamic behavior of the spillway dam has also been proposed. |
