首次将随机波浪荷载应用于圆沉箱防波堤的动力分析,并将其动力运动过程分为摇摆和摇摆-滑移运动两种运动模态.引入了控制侧向滑移的阻滑板-阻尼器系统,提出了一种新的摇摆-滑移动力分析模型,建立了相应的运动方程.根据圆沉箱结构的特点提出了附加质量等动力参数的计算公式以及新的地基刚度系数转换关系.利用Fortran语言环境编写程序,按此动力模型和方法对工程实例进行计算,计算结果表明了本模型和方法对随机波浪荷载作用下圆沉箱防波堤动力响应的数值求解的可行性和有效性.
For the first time, the random wave loads are applied to the dynamic analysis of the breakwater of round caissons, and the dynamic movement process is divided into two kinds of movement modes: sway and sway-slip movement.A sliding plate-damper system is introduced to control the lateral slip, A new model of rocking-sliding dynamic analysis is proposed, and corresponding equations of motion are established. According to the characteristics of circular caissons, the formulas of additional dynamic parameters such as mass and the conversion relation of the stiffness coefficient of foundation are proposed. Fortran language environment The program is calculated and calculated according to the dynamic model and method. The calculation results show the feasibility and effectiveness of the proposed model and method for numerical solution of the dynamic response of the round caissons breakwater under random wave loads.
