Abstract

This paper presents improved dispersion analysis of the surface wave method for estimations of shear wave velocity profile at near surface soils. The conventional surface wave analysis has limited capability to reduce the irregularities and other noises in the dispersion curve. The frequency-wavenumber (f-k) domains analysis with fitting criteria and different mode analysis is presented to obtain reliable dispersion curve of surface wave velocities. The irregularities and noises presented in absolute dispersion curve can be reduced using updated technique with f-k analysis. The significance of the paper is to show how reliable apparent dispersion curve is obtained through f-k transformation with fitting criteria implemented in the MASW method.
