Centrifuge model tests were conducted to clarify the basic characteristics of resistance to caisson overturning of a reinforcing embankment composed of wave-dissipating blocks. The behavior of the reinforcing embankment during caisson overturning was observed by static loading tests, and the resisting moment was measured. It was found that the resisting moment tended to increase as the inclination angle increased, but as the inclination angle increased, the reinforcing embankment were deformed and the initial resisting force against repeated external forces decreased. However, for a small tilt angle of 0.5 degrees, the deformation of the embankment is small, and the resistance force is maintained against the repetitive external force. As for the effect of the shape of the embankments on the resisting moment, the shape effect is relatively small if the number of total blocks is the same. However, it is effective to make the height of the embankments higher than the thickness of two layers.
