【摘要】 选择福建沿海地区两种不同岩土工程地质条件的场地,通过实测地微动信号并进行相关分析、频谱分析,讨论了场地土对地微动的频率响应特征。结果表明,不同土层岩性对地微动的放大与滤波作用具有各自的特点,场地土对地微动的响应存在着频率依赖、频率选择现象。更多还原

【Abstract】 Microtremor signals are observed in situ at Fujian coastal site with different engineering geological conditions. The signals are auto-correlated and analyzed by FFT,and the characters of frequency response of site on microtremor signals are discussed. The results show thatthere are respective characters of magnifying and filter on microtremor for each site with different geoogical condition,and frequency-depen-dence and frequency-selection for the response of site on microtremor.更多还原
