摘　　要：The random wave load is applied to dynamic response analysis of circular caisson breakwater. The motion process of circular caisson breakwater is classified as rotation motion mode and rotation-and-sliding motion mode. The dynamic model system composed of damper-antislider to control the lateral sliding is introduced, and corresponding dynamic equations of two motion modes are established. The formulas to calculate added mass and new conversion relation of the unit rota- tional stiffness coefficient are put forward according to the characteristic of the circular caisson breakwater. An engineering case is calculated by a program compiled in Fortran language using proposed dynamic model and method. The validity of the model is calibrated.随机的波浪负担被用于圆形的沉箱防波提的动态反应分析。圆形的沉箱防波提的运动过程作为旋转运动模式和 rotation-and-sliding 运动模式被分类。动态模型系统填写了 ofdamper-antislider 控制侧面的滑动被介绍，并且二个运动模式的相应动态方程被建立。计算增加的质量和单位的新变换关系的公式旋转僵硬系数根据圆形的沉箱防波提的特征被提出。设计的格被用建议动态模型和方法用 Fortran 语言编译的一个程序计算。模型的有效性被校准。
