Abstract
The Spectral analysis of surface waves (SASW) method has been successfully used in evaluation of elastic moduli profiles of layered systems. Recently, there have been attempts to implement the SASW method and surface waves in evaluation of damping/attenuation properties of layered systems. Results of numerical simulations are presented for the purpose of explanation of effects of damping properties of individual layers on the overall attenuation properties, as measured during actual SASW testing. A parametric study conducted examines effects of a number of parameters, including the system stratification that may lead to dominant wave propagation in terms of higher Rayleigh modes. Correlations between the overall attenuation characteristics and soil stratification, effect of higher Rayleigh modes, damping characteristics of individual layers, was found to be similar to correlations for the surface wave velocity.
