Assessment of soils compaction using multichanel analysis of surface wave

Abstract : The shear properties of soils are of fundamental interest in civil or environmental engineering, particularly for designing building foundations or predicting site effects in seismic hazard studies. Dynamic compaction improves the soils mechanical characteristics obtained by in- situ investigations (cone penetration tests (CPTs). Vs profiles obtained by inversion of surface wave before and after compaction have allowed a good evaluation of the compaction performance and demonstrate the potential of this technique in geotechnical investigations
