摘要：Taking the loess slope covered on mud rock as a research site, this study is based on theoretical foundation of the Horizontal-to-Vertical Spectral Ration(HVSR) and Sediment-to-Bedrock Spectral Ration(SBSR), site earthquake response of the loess landslide covered on mud rock calculated by use of the software FLAC3D, dynamic response of earthquakes was revealed, the simulation between HVSR and SBSR has been discussed, applicability of HVSR has been was analyzed. The results show that: The maximum horizontal displacement is found in the cliff part of the slope, the peak acceleration is the largest at the back edge of the slope and the vertical interface, as the elevation increases, the dominant frequency moves toward the lower frequency, and the higher frequency components are absorbed, the dominant frequencies obtained by HVSR spectrum ratio and SBSR spectrum ratio, and they are basically consistent with the fourier spectrum, the amplitude of HVSR and SBSR spectrum ratio are similar to the change rule of peak acceleration. Therefore, HVSR method can be applied to study the site effect of loess slope covered on mud rock.
