【Abstract】 The models of interaction between breaking wave and breakwater,elastic vibration,sliding motion and rocking motion of breakwater are presented.The models are used to simulate the processes of vibrating-sliding-rocking motion of upright breakwater under breaking wave impact.The effect of each motion on the breaking wave force,displacement,rotation,sliding force and overturning moment of breakwater is investigated.The reason of the difference between Minkin and Goda formulae for breaking wave pressure is also discussed.更多还原
