| 摘 要： | 首次将随机波浪荷载应用于矩形沉箱防波堤的动力分析，并将其动力运动过程分为：摇摆、摇摆一滑移运动两种运动模态，同时引入了侧向阻滑板一转角弹簧一阻尼器和阻滑板一竖向弹簧一阻尼器两种模型体系，建立了相应的动力计算模型，推导出了各运动模态的动力方程，并分别采用Fortran语言编译的程序和有限元软件ANSYS对两种模型进行实施。通过实例的计算分析表明，两种模型和方法均可有效地对随机波浪作用下沉箱防波堤动力响应进行数值模拟，而后者更符合实际受力情况，精度更高。

| Abstract: | Random wave load is applied to dynamic response analysis of rectangular caisson breakwater for the first time, and the motion process of rectangular caisson breakwater is classified as rotation motion mode and rotation-slidlng motion mode corresponding to the lateral antlslider-rotation spring-damper sys- tem and the lateral antislider-vertical spring-damper system. The dynamic equations of two motion models are established and a program compiled by Fortran language and ANSYS program are utilized for the solution. It is shown from the engineering example that both proposed models and methods can be applied to simulate the dynamic response of rectangular caisson breakwater subjected to random wave loads effectively, the latter of which is more consistent with the working pattern with higher precision. |
