This paper describes a measurement campaign of the shear wave velocity from in situ tests and laboratory tests. The results from all tests are presented and compared. The shear wave velocity has a direct relationship to the shear modulus, an important parameter for earthquake engineering. The research is performed on Belgian Boom clay. The Seismic Cone Penetration test (SCPT) and the Spectral Analysis of Surface Waves (SASW) test are preformed at the research site in order to obtain the in situ shear wave velocities propagating both in vertical and horizontal directions. In the laboratory, undisturbed specimens are tested in triaxial cell with multi-directional bender elements under isotropic consolidation stresses of 100, 200 and 400 kPa. Using bender element technique, shear wave velocities propagating in vertical and horizontal directions are directly obtained in the undisturbed Belgian Boom clay sample. Laboratory results are widely consistent with In situ data.
