MODEL VIBRATION TEST OF SHEET-PILE QUAY WALL WITH PERSISTENT BACK-FILLING COMPOSED OF STEEL-MAKING SLAG

Abstract

 While the importance of national resilience has been recognized and various studies on the redundancy and ductility in harbor structures are being conducted, new persistent geo-material that is a mixture of steel-making slag and dredged soil has been suggested by the authors. In this study, seismic resistance characteristics of the new geo-material were examined by model vibration test of sheet-pile quay wall. Through comparative study with cement improved soil, it was manifested that crack growth and deformation of the new geo-material was more limited, and shear resistance properties were more prominent than cement improved soil.
