群桩是海岸和海洋工程中广泛使用的结构，如跨海桥梁和海上风力涡轮机基础。在计算桩上波浪力时，必须考虑群桩的影响。另外，真实的海浪是多向的。然而，相关的法规和研究主要集中在单向波对群桩的作用。考虑多向不规则波与群桩相互作用的研究较少。在这项研究中，我们实验研究了多向不规则波之间的相互作用和一个小规模的，垂直的底部安装的桩群，包括9个桩并排排列。提出了一个新的参数KCLD 1/3= KC 1/3×L/D，以综合考虑相对桩径D/LandKC 1/3数对波浪纵向力和横向力的影响。结果表明，定向传播对多向不规则波与桩的相互作用，尤其是桩的横向力有显著影响。研究了波浪力、横向力和合力之间的关系，确定了不同桩型间波浪力的差异。这些结果可为工程结构的设计提供参考。
Pile groups are widely used structures in coastal and ocean engineering, such as in cross-sea bridges and offshore wind turbine foundations. The effect of a pile group must be considered when calculating the wave forces on piles. In addition, real sea waves are multi-directional waves. However, the associated regulations and studies have mainly concentrated on the action of a unidirectional wave on pile groups. Few studies have considered the interactions between multi-directional irregular waves and pile groups. In this study, we experimentally investigated the interactions between multi-directional irregular waves and a small scale, vertical bottom-mounted pile group comprising nine piles in a side-by-side arrangement. We propose a new parameter:KCLD1/3=KC1/3×L/D, to comprehensively consider the effects of the relative pile diameterD/LandKC1/3number on the wave inline force and transverse force on piles. The results show that directional spreading has a significant effect on the interaction between multi-directional irregular waves and piles, especially on the transverse force of piles. The relationships between the inline force, transverse force, and resultant force are studied, and the differences in the wave force among different piles are determined. These results may provide a reference to facilitate the design of engineering structures.
