Abstract: The ability of the spectral analysis of surface waves (SASW) test to detect underground obstacles has been investigated. The SASW test is simulated by the finite-element method. The fluctuations in the dispersion curve, ...

Abstract: The usual inversion procedures for spectral analysis of surface waves (SASW) testing assume that only one Rayleigh mode is dominant, and thus fail to give reliable results for irregular soil profiles and some complex ...
