Field work for K-NET sites IBR014 and CHB005 in Japan (September, 2015)

Robert Kayen, Paolo Zimmaro, and Dong Youp Kwak performed field work assessing Vs profiles and ground water table using SASW and GPR (ground penetration radar) for K-NET sites IBR014 and CHB005.

Field work for selected sites in Mihama-ward, Chiba in Japan (June, 2015)

Dong Youp Kwak performed field work assessing undistrubed samples to be used for tri-axial tests along with lab tests for sites in Mihama-ward, Chiba, Japan. Surface soils of this region are hydraulic fills formed 1970s, compoased of clays to clean sands depending on hydraulic fill discharge process. The selected sites for advanced lab tests had severe, marginal, and no liquefaction performance during 2011 Tohoku earthquake.

Field work (SASW) for selected sites in Tokyo / Chiba in Japan (July, 2015)

Robert Kayen and Japanese graduate students from Tokyo Tech performed field work assessing Vs profiles for 12 sites where CPT and SPT were assessed at 2014.

Field work (SPT / CPT) for selected sites in Tokyo / Chiba in Japan (June, 2014)

Allan NG performed field work assessing SPT and CPT as well as lab test results for selected sites in Japan. The selected sites are either strong motion observation or ground deformation sites for 2011 Tohoku earthquake.
