在波浪从深水向浅水传播过程中 ,考虑弱非线性效应具有重要的实用价值 ,因此得到广泛的讨论和研究。本文根据文献 [6 ]导出的考虑能耗的定常缓坡方程 ,结合文献 [5 ]给出的显式非线性弥散关系 ,得出了含弱非线性效应的缓坡方程 ,用该方程对浅水中波浪的传播进行了计算 ,将计算结果和试验数据进行了比较 ,结果表明 ,含弱非线性效应的缓坡方程可以用于讨论浅水中波浪传播的弱非线性效应 ,所得计算结果与试验结果更为吻合。 In the process of wave propagation from deepwater to shallow water, considering the weak nonlinear effect has important practical value, so it has been widely discussed and studied. Based on the steady gentle slope equation considering energy consumption derived from [6] and combining with the explicit nonlinear dispersion relation given in [5], a gentle slope equation with weak nonlinear effect is obtained in this paper. Using this equation, The results are compared with the experimental data. The results show that the mild slope equation with weak nonlinear effect can be used to discuss the weak nonlinear effect of wave propagation in shallow water. The calculated results are in good agreement with the experimental results.
