Abstract:
Three seismic methods were used to acquire shear wave velocity at a test site: crosshole test, seismic refraction (using S waves, which are not used as frequently as P waves in seismic) and Multichannel Analysis of surface Waves (MASW). These methods were comparatively evaluated. The crosshole data, considered to be more accurate than other methods data, were used as a “yard stick” for evaluating the accuracy of MASW shear wave velocity data. The results show a good agreement between the surface seismic methods data (seismic refraction and MASW) and the crosshole test data (performed in boreholes).
