A new kind of quay-wall structure using geosynthetics has been proposed for renovating existing sheet-pile quay-wall structures to increase their earthquake resistance capability. The proposed structure adopts the combined techniques of stabilized soil and geogrid for a quay wall, which is referred to simply as an ‘SG-WALL’. This paper presented a numerical comparison study on quay-wall structures improved by SG-WALL method and the traditional anchor-pile reinforced method. The analysis results showed that SG-WALL method has a better effect to improve the seismic performance of a quay-wall structure than the traditional anchor-pile improvement method.
