| 摘 要： | 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。

| Abstract: | 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. |
