Dynamic behavior of sheet pile quay walls is not sufficiently investigated because of a few case histories of sheet pile quay wall damages during 1995 Hyogoken-nambu earthquake. A series of centrifuge model tests and 2-dimensional finite element analyses based on effective stress concept were conducted to investigate the stability of sheet pile quay walls during earthquakes. Two actual quay walls were modeled in the tests and the analyses and subjected to examination in this study: the south quay wall of Fishery Wharf at Kushiro East Port and the south quay wall of wharf No.1 at Kushiro West Port as damage and no-damage cases, respectively. Results of the model test and the numerical analysis corresponded well with the actual residual deformation of sheet pile quay walls.
