在水线上有大直径柱子的海上结构物对周围的波浪场造成了显著的扰动，并在柱子周围产生了较大的爬升。本文讨论了在规则正弦波和具有极端风暴波特征的聚焦波群中对这一效应的预报。给出了竖直圆柱体的线性和二阶非线性解析解。然而，对于非常大的波浪，需要进行完全的非线性分析，这必须基于时间和空间维度的数值离散。简要介绍了一种预报陡波与近海结构物相互作用的有限元方法。
Offshore structures having large diameter columns at the waterline cause a significant disturbance to the ambient wave field, and large run–up around the columns. The paper discusses prediction of this effect in regular sinusoidal waves and in focused wave groups characteristic of extreme storm waves. Results are obtained from linear and second–order nonlinear analytical solutions for vertical circular cylinders. For very large waves, however, a fully nonlinear analysis is needed, which must be based on numerical discretization in both temporal and spatial dimensions. A finite–element procedure for predicting the interaction of steep waves with offshore structures is briefly introduced.
