Generation of random shear wave velocity profiles using harmonic wavelet transform

A soil site always has a spatial variation of a shear wave velocity which could cause an uncertainty of a result of a seismic site amplification analysis. This kind of a uncertainty can be managed by a Monte-Carlo (MC) simulation using the random shear wave velocity profiles which can exist in the target site. In this paper, the method based on Harmonic wavelet transform (HWT) is proposed to generate the random shear wave velocity profiles for a given site from a limited number of the field Vs profiles. The proposed method is applied to a field in Korea to show a feasibility.
