| 摘 要： | 本文应用理论推导及数值计算方法,对浅海非线性随机波浪的荷载谱进行了研究;将波面方程、海水质点的水平速度及加速度分解成一阶和二阶分量,通过引入Hermite多项式,得到了波面方程与其一阶分量的自相关函数之间的关系,从而确定了一阶波面分量的谱密度,进而得到了单位桩柱长度上的波浪力及总波浪力的谱密度。

| Abstract: | The wave force spectra of nonlinear random sea waves in shallow waters is studied in this paper by theoretical derivation and numerical computational methods. This is done by decomposing the wave profile and the velocities and accelerations of water particles into first and second order components. The relationship between autocorrelation functions of wave profile and its first order component is then determined by introducing Hermite polynomial. The spectral densities of the velocities and accelerations of water particles, the wave forces on unit pile length and the total wave forces are obtained in the same way. |
