Abstract
: In this paper, the results of geophysical surveying methods based on the surface waves are presented. Surface wave velocity dispersion depending on the frequency or spectral analysis was used for subsurface soil properties evaluation. Multichannel analysis of surface waves (MASW) seismic cross sections and spectral analysis of surface waves (SASW) seismic soundings were compared with results of non-dispersive seismic refraction and down-hole methods. In order to analyse the estimated value of soil stiffness derived from the shear wave velocity, geotechnical penetration tests (Standard Penetration Test, SPT and Dynamic Probe Heavy, DPH) were conducted. Statistical correlations of shear wave velocity (vs) and dynamic penetration test blow counts (SPT-N and DPH-N) have revealed high confidence of the estimated soil stiffness based on the surface wave velocity for Eurocode 8 (EC8) ground types.
