Session report: Applications of shear wave velocity on various geotechnical problems

The shear wave velocity (V-s), which is directly related to the small strain shear modulus, G(max), has a great potential in the applications of various geotechnical problems. In this paper, the advantages of using V-s in geotechnical applications are illustrated and the main features of various intrusive and non-intrusive V-s measuring techniques in the field are summarized. The V-s has been applied to the various geotechnical problems including not only traditional earthquake related problems but static deformation analysis. The procedure to evaluate the degree of consolidation using V-s during the ground improvement of soft clay is discussed in detail and applied in the Busan Newport construction site. The degree of consolidation evaluated using the V-s matched well with that obtained from field settlement record, showing the potential of using V-s in the evaluation of degree of consolidation. Finally, the papers submitted to the session TS6 are briefly discussed.
