f INTEGRATION OF DOWNHOLE ACOUSTIC TELEVIEWER IMAGING, ULTRASONIC LABORATORY SHEAR WAVES VELOCITY MEASUREMENTS AND MULTI-CHANNEL ANALYSIS OF SURFACE WAVES FOR GEOTECHNICAL SITE CHARACTERIZATION: RILEY AND DOUGLAS COUNTIES SITES, KANSAS, USA

Geotechnical site characteristics are a function of the subsurface elastic moduli and the geologic structures. This study integrates borehole, surface and laboratory measurements for a geotechnical investigation that is focused on investigating shear wave velocity variation and its implication to geotechnical aspects of two sites in eastern Kansas. The area has a potential of seismicity due to the seismic zone associated with the Nemaha formation where earthquakes pose a moderate hazard. This study is in response to recent design standards for bridge structures require integrating comprehensive geotechnical site characterization.
