EXPERIMENTAL STUDY ON THE SEISMIC PERFORMANCE OF THE SHEET-PILE FOUNDATION

概要

論文の詳細を見る
A new bridge foundation named "Sheet-pile foundation" is proposed. Sheet-pile foundation consists of a footing and sheet piles surrounding the footing. By installing sheet piles into the ground around the footing and connecting together, both overturning and sliding resistance of the foundation against the seismic action will be increased. This technique can be applied as the seismic retrofit method of foundations as well. In this study, the seismic performance of the sheet-pile foundation is experimentally investigated. 2 series of shaking table tests under the centrifugal gravity were performed, with utilizing model foundations with 5m square footing as the prototype.
