摘要

An empirical mode decomposition (EMD)-based procedure is proposed in this paper to evaluate the experimental dispersion curve of the surface wave (SASW) method. Four field sites were selected to validate the advantages of the suggested EMD-based procedure for determining shear wave velocity profiles, which are also compared with those obtained by using suspension PS logging tests. The results show that the EMD-based procedure can reduce the effects of noise and higher modes on the experimental dispersion curve, and thus can improve the reliability of the evaluated shear wave velocity profiles. In addition, the effective depth of the shear wave velocity profile evaluated by using the SASW method can also be increased when the EMD-based procedure is introduced.
