The author used the records of motion on some major earth dams in recent twenty years, including Tunghsing Dam, Jenyih Dam, Tsengwen Dam, and Nanhua Dam, to make some analysis in the time and frequency domain, such as producing acceleration history, velocity history, displacement history, fourier spectrum, and response spectrum. Then, the vibration characteristics of the analyzed earth dams could be identified. It shows that the responses of motion in time domain are the largest in transverse direction at the top of the dams. There are some significant correlations between PGA, PGV, and PGD in different directions and positions at the dams. In frequency domain, the resonant frequency of the dams seems to relate to their heights considerably. en_US DC.subject 地震 zh_TW DC.subject 共振頻率 zh_TW DC.subject 反應譜 zh_TW DC.subject 傅氏譜 zh_TW DC.subject 時間歷時 zh_TW DC.subject 土石壩 zh_TW DC.subject Time History en_US DC.subject Earth Dam en_US DC.subject Fourier Spectrum en_US DC.subject Earthquake en_US DC.subject Resonant Frequency en_US DC.subject Response Spectrum en_US DC.title 臺灣土石壩中小地震記錄之分析 zh_TW dc.language.iso zh-TW zh-TW DC.title Analysis of Seismic Records of Earth Dams Subjected to Small and Moderate Earthquakes in Taiwan en_US DC.type 博碩士論文 zh_TW DC.type thesis en_US DC.publisher National Central University en_US
