摘要为了研究短峰波与复杂桩群之间的相互作用,进行了一系列波池实验。在我们以前的研究中,已经显示了短峰随机波和九个并排布置的桩群之间的相互作用的统计分析。作为平行研究,本文对短峰随机波浪作用于双排并列式8根小桩群桩进行了试验研究。给出了群桩效应系数随KCLD 1/3参数和定向扩展标准差σθ的变化规律。阐明了群桩的纵向力、横向力和合力之间的关系,确定了群桩的波浪荷载。结果表明,波浪方向性对短峰随机波浪对群桩结构的作用,特别是对桩的横向力有重要影响。由于排桩之间的相互作用,双排并排布置的群桩效应比单排并排布置的群桩效应弱。
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.
