Abstract
This study introduced a solution to renovate a caisson-type gravity quay wall by grouting and deepening and investigated its dynamic behavior using the geo-centrifuge test. The experiments were conducted for both existing and renovated quay walls. During the tests, the acceleration and caisson displacements were recorded. The results indicated that both models increased acceleration from the base to the surface. However, the increase in the renovated quay wall was lower than that of the existing case. The deformed shape of the caissons was different between the two cases. In the case of renovated quay wall, the caisson slipped horizontally, while in the existing case, it rotated to the seaside. The displacements of the caisson significantly decreased after renovation, implying that damage resistance increased.
