N2 - The shear wave velocity (VS) profile has been used as one of the key design parameters for the analysis of static deformations as well as for the seismic design of geotechnical structures. Various seismic methods are widely used for site characterization and can be grouped as intrusive and non-intrusive methods. Each seismic test has its own special features, merits and demerits, and applicability to evaluate spatial stiffness variation, and it is important to evaluate and understand those characteristics to use it properly. For comparative study of field seismic tests, round robin test was performed at Seohae Grand Bridge site in Korea. Three universities, five site investigation companies, and one research institute have participated. Intrusive methods used in this study include borehole seismic tests such as downhole, crosshole, SPT based uphole, and Suspension PS logging methods as 1-D characterization of VS profile. For non-intrusive stiffness evaluation of a site, surface wave methods such as SASW, MASW, HWAW, ReMi methods are utilized for 1-D and 2-D characterizations. Discussing points in this study include (1) the reliability and limitation of each method, (2) the cause of difference in results (3) the suggestions for better VS profile evaluation, (4) the feasibility of 2-D subsurface image mapping based on surface wave methods.
