建立了沉箱式防波堤弹性振动—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——摇摆运动过程进行了数值模拟，并研究了摇摆运动对防波堤位移、转角、滑移力和倾覆力矩的影响。结果表明，摇摆运动可有效减小防波堤的的滑移力和倾覆力矩。在防波堤设计中可考虑允许出现摇摆运动，以实现更为经济的结构设计。
建立瞭沉箱式防波隄彈性振動—搖襬運動分析模型，對破碎波遲擊作用下防波隄的彈性振動——搖襬運動過程進行瞭數值模擬，併研究瞭搖襬運動對防波隄位移、轉角、滑移力和傾覆力矩的影響。結果錶明，搖襬運動可有效減小防波隄的的滑移力和傾覆力矩。在防波隄設計中可攷慮允許齣現搖襬運動，以實現更為經濟的結構設計。

The model for analyzing caisson vibration and swinging motions was set up and the numerical simulation of breakwater elastic vibration and swinging motions under the action of breaking wave was made.The effect of swinging motion on the breakwater displacement,angle of rotation,sliding force and overturning moment were studied.The results show that the sliding force and overturning moment can be reduced by swinging motion.It can be considered that swinging motion is allowed to appear in the design in order to realize the more economic structural design.
