| 摘 要： | 目前,采用随机性分析方法计算不规则波对海洋结构物作用时一般均采用Airy波理论,并未考虑波浪非线性的影响。本文基于二阶Stokes非线性波浪理论探讨了采用非线性波浪理论时随机波浪力谱的计算方法,并用一典型算例,对本文公式的计算结果与线性波理论的计算结果进行比较。计算结果表明,在水深较深时不能忽略波浪非线性的影响。

| Abstract: | The Airy wave theory is usually adopted in the calculation of the wave force with neglecting the influence of non-linear wave.By using the second order Stokes wave theory,the wave force is calculated and the method to deduce the formula of the second order Stokes wave force spectrum is explored.A representative example is given,and the results from calculation are obtained in the form of curves for comparison.Results show that the influence of the non-linear wave can't be neglected when the depth of water is great. |
