AN ESTIMATING METHOD FOR A PHASE-VELOCITY OF RAYLEIGH WAVES ON MULTI-LAYERED MEDIA AND ITS APPLICATION TO INVERSION PROBLEM

Abstract

An estimating method for a phase velocity of fundamental-mode Rayleigh waves on multi-layered media is proposed. This method needs only S wave velocity and thickness of each layer. The applicability of this method is examined with a series of numerical simulation. As a result, the phase velocity estimated by this method is fairly close to the exact value. Based on this method, then we apply this method to estimate Vs-profile of ground.
