Abstract
This paper describes the results of shaking table tests and effective stress analyses to investigate effect of seismic reinforcement for gravity type quay walls using ground anchors. As a result, the following conclusions are obtained. 1) Caisson displacement is constrained with the ground anchors due to the tensile force. 2) Dynamic behavior of quay walls with ground anchors is not affected by the difference of rubble mound layer thickness. 3) The relationship of the ground anchors between the tensile force and the elongation shows a hysteresis loop. 4) Effect of the ground anchors is confirmed by the analyses considering of both non-linear characteristic of the sand and the ground anchors.
