海上桩基支撑结构不规则波波浪力实验研究

Experimental study of the wave forces on the offshore pile-supported structures in irregular waves

该文针对几种典型桩基支撑结构,实施了一系列不规则波波浪物理模型实验。通过分析波浪力和波要素等实验结果与桩基支撑结构几何特征尺寸之间的关系,提出了当量直径的概念。归纳了统一的桩基支撑结构不规则波波浪力经验公式,同时在此公式的基础上探究了群桩系数的变化规律。

Based on several typical pile-supported structures, a series of physical model experiments in irregular waves were conducted. Through analyzing the relationships between the experimental results of wave loads, wave elements and the characteristic geometric scales of pile structures, an equivalent diameter was proposed. Unified empirical formulas of wave loads for pile-supported structures in irregular waves were obtained, and the variations of pile group effect coefficients were investigated on the basis of the empirical formulas.
