| 中文摘要: |
| 根据大直径薄壁圆筒防波堤的受力特征，提出了防波堤可能出现的3种运动模态：摇摆运动、摇摆-小滑移运动和摇摆-大滑移运动。引入控制侧向滑移的阻滑板-弹簧-阻尼器，建立了在随机波浪荷载作用下的大直径薄壁圆筒防波堤的动力模型，并建立了相应的运动方程。根据大直径薄壁圆筒结构防波堤系统的特点，提出了其附加土质量和其它参数计算公式。通过实例验证，表明本模型对随机波浪荷载作用下大直径薄壁圆筒防波堤动力响应数值模拟是可行的、有效的。 |

| The motion of large diameter cylinder breakwater under the action of random waves consists of three parts: rotation, rotation_small sliding and rotation_large sliding. A model for describing the motion of the cylinder composed of spring_dashpot_antislider for controlling the lateral sliding is introduced and the corresponding motion equation is established. The formula for calculatin
g the additional soil mass and other parameters are deduced according to the characteristics of the large diameter cylinder breakwater. The validity of the model is verified by an example. |
