| Abstract: | Taking the strong motion observation on some concrete dams (such as Danjiang dam, Gezhouba dam, Xinfengjiang dam and Tanling dam) as instances, the instruments and measuring method used in vibration observation of a prototype concrete dam and the preliminnary result obtained are introduced in this paper. The contents of antiseismic analysis on concrete dams, including the dynamic structure characteristic analysis, the stability analysis and the strength computation of dams, and the antiseismic analysis method, including the preudostatics method and response spectrum method, are presented briefly. Finally, the results from using the strong motion observation records to make the antiseismic analysis for Xinfengjiang dam and Tanling dam are discribed in detail, and the importance of the observation for earthquake prevention and protection for concrete dam is shown. |
