摘要
为了更好地模拟实际波浪的非线性和洋流的影响,该文介绍了一种适用范围广,边界条件拟合好,可考虑洋流作用的非线性波浪理论——流函数波浪理论。将流函数波浪理论计算得到的部分结果与线性波理论计算得到的相关结果进行比较,结果表明流函数波浪理论能够很好地考虑波浪的非线性;初步探讨了流函数波浪理论在考虑洋流作用方面的优势;最后推导了流函数波浪理论在海底的随时空分布的波压力公式,比较了非线性波浪荷载与线性波浪荷载。
To simulation nonlinearity and the impact of ocean currents of actual wave, stream function wave theory which is a wide scope, good boundary conditions, considering currents nonlinear wave theory is introduced. Part of the results with related results calculated by linear wave theory obtained were compared, the results show that the stream function wave theory can consider nonlinearity of wave well; the advantages of the stream function wave the- ory in considering the role of ocean currents is explored; wave pressure formula for the distri- bution of time and space on the seabed is derived in the last, nonlinear wave load with linear wave load is compared.
