摘　　要：采用复数响应法，研究日本大阪上町逆断层地表地震响应．根据谐波震动分析和阪神地震实测地震波非线性动力计算，得到深部断层影响下的地震响应分布规律及频率特性．研究表明：深部断层对地震响应产生影响，使地表出现地震响应“增强带”及“干扰带”．In this paper,the complex response method is used to study the earthquake response of the earth′s surface of Uemachi fault in the city of Osaka Japan.According to harmonic wave analysis and nonlinear dynamic calculation based on the observed seismic wave during Osaka Kobe earthquake,the distribution regularity and frequency characteristics of earthquake response influenced by the fault are obtained.The result shows that owing to the existence of the fault the earthquake response is affected,and the strengthening zone and interference zone of response appear on the earth′s surface.
