| 摘 要： | 提出了有限振幅波对复合圆柱绕射波浪力（矩）的一种实用计算方法．在Ｓｔｏｋｅｓｎ阶绕射波速度势已定条件下，用此法可对ｎ＋１阶水波所致波浪载荷进行积分形式的工程估算．实算中对慢收敛的无限自由表面积分可采用数学上的渐近方法化简运算；对直立圆柱第２阶波浪力的实算结果与有关实验数据吻合良好．

| Abstract: | A utility method is presented and used to calculate the Stokes finite amplitude wave forces on vertical circular cyclinders commonly used in offshore structures. The n 1 order diffracted wave loads may be evaluated by using this method when the n order wave velocity potential is given. A special asymptotic method may simplify the calculation of the nonlinear term integral over infinite free surface. The results of second order diffracted wave forces on an isolated surface piecing vertial cylinder tally with the related experimental data. |
