DYNAMIC CENTRIFUGE MODEL TEST ON PILED GEO-WALL

Abstract

This paper proposes a new application of pile foundation to reinforced soil structure by geogrid, in order to improve horizontal resistance of the structure. In this study, the effectiveness of the application and dynamic interaction between pile and reinforced soil structure were confirmed from the results of a dynamic centrifuge model test (25G), and a design method of the reinforced soil structure with using piles (Piled Geo-wall) was proposed through the numerical simulation of the experiment by using two dimensional dynamic FEM analysis.
