摘要：

In this paper, a two-dimensional S-wave velocity profile inversion method was introduced by the use of H/V spectra and dispersion curves. In the inversion process, a 2.5-dimensional analysis of the wave field due to incident surface (Rayleigh and Love) waves was conducted as a forward analysis assuming that microtremor is considered as composition of waves coming from a variety of directions. Based on the numerical analysis, the proposed method shows a possibility to get a very positive result in the irregular ground. It is also found, however, that enough information about the sources such as incident angle and made of surface wave is necessary for the proposed method.
