ABSTRACT A series of wave basin experiments have been conducted to investigate the interactions between short-crested waves and complex pile groups. A statistical analysis of the interactions between short-crested random waves and a pile group with nine piles in a side-by-side arrangement has been shown in our previous study. As a parallel study, the short-crested random wave action on a pile group with eight small-scale piles in a double-row side-by-side arrangement is experimentally investigated in this paper. Variations in the coefficients of the pile group effect with the KCLD 1/3 parameter and standard deviation σθ of directional spreading are given. The relations of the inline force, transverse force, and resultant force are illustrated, and the wave loading of the piles in the group is ascertained. The results show that wave directionality plays an important part in the short-crested random wave action on pile group structures, especially on the transverse force of the piles. The pile group effect in a double-row side-by-side arrangement is weaker than that in simply a one-row side-by-side arrangement due to interactions between the rows of the piles.

双排并排桩群短顶随机波相互作用试验研究：统计分析

摘要 已经进行了一系列波盆实验来研究短波峰与复杂桩群之间的相互作用。在我们之前的研究中已经展示了对短波峰随机波与九桩并排排列的桩组之间相互作用的统计分析。作为平行研究，本文以双排并排布置的8个小型桩群对短顶随机波作用进行了实验研究。给出了桩群效应系数随 KCLD 1/3 参数和方向扩展的标准偏差 σθ 的变化。说明了直线力、横向力和合力的关系，并确定了群桩的波浪载荷。结果表明，波浪方向性在短顶随机波浪作用对群桩结构，特别是对桩横向力的作用中起重要作用。由于各排桩之间的相互作用，双排并排布置的桩群效应比简单的单排并排布置的桩群效应弱。
