摘要

摘要: 波浪的方向分布对波浪的传播及其与工程结构物的作用都具有明显影响，目前现有的研究大多是基于单向波浪进行的。为了研究方向分布对群墩结构上的爬高影响，基于规则波浪与群墩作用的理论解，结合多向不规则波浪的造波方法，建立了多向不规则波浪与群墩作用的计算模型，同时进行了物理模型试验对模型的有效性进行了验证。系统地对群墩周围及表面上的波浪爬高进行了计算分析，结果表明，方向分布对波浪爬高具有较大的影响，且不同位置处的影响并不相同，在实际的工程设计中如果按照单向波浪计算，可能低估或者高估群墩周围的爬高。

Abstract: The wave directional distribution has a significant effect on the wave propagation and its interaction with offshore structures. Most of the researches are based on unidirectional waves. In order to study the effect of directional distribution on the wave run-up on cylinders, a numerical modeling of multidirectional waves interaction with an array of cylinders was established based on the linear theory of wave interacts on an array of cylinders combined the method to generate multidirectional wave. A wave basin experiment was carried out, and the numerical calculation results were verified by the results of the physical experiment. The wave run-up around cylinders was calculated systematically, the results show that wave directional distribution has significant effects on wave run-up, and the effect is also based on the position around the cylinders. In the engineering design, if the calculation is based on unidirectional wave, it may underestimate or overestimate the wave run-up around the cylinders.
