Dynamic Centrifuge Model Tests on Pile Foundation of Plate-shape Building in Soft Clayey Ground and its Numerical Analyses

Abstract

A dynamic centrifuge model tests were carried out to investigate the seismic behavior of a plate-shape building's pile foundation in the soft clayey ground. Also, the detailed seismic response analysis was carried out to confirm its reproducibility. It was confirmed that it was easy to stabilize the clayey ground made by wet-tamping method and the dynamic response of the building and the pile's stress were well-represented by the analyses, even if the shear strain of the clayey ground was increased by the strong motion.
