Description
In this study, we conducted microtremor array exploration at a site with inclined bedrock to deduce S-wave velocity in shallow soil. The S-wave velocity of the 1st layer and the depth to engineering bedrock evaluated from microtremor array exploration are consistent with the results of measurement-while-drilling, surface wave exploration method and H/V spectra of microtremors. In order to estimate the effect of bedrock inclination on the phase velocity, 2D model was constructed from aligning the 1D profiles. The difference between the phase velocities from FEM analysis with the 1D and 2D models can be recognized in the long period range.
