摘　　要：分别建立了直立式防波堤与破碎波相互作用、防波堤的弹性振动、滑移运动和摇摆运动分析模型 ,对破碎波冲击作用下防波堤的弹性振动—滑移运动—摇摆运动过程进行了数值模拟 ,研究了各种运动对破碎波冲击力及其作用效应—防波堤的位移、转角。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.
