| 摘 要： | 本文用谱分析方法对方柱群墩结构在不规则波作用下的相互影响进行了计算。研究了在不同入射波向时每个方墩的群墩影响系数随墩距变化的规律并与折算圆墩的结果进行了比较。入射波谱采用Ｂｒｅｔｓｃｈｎｅｉｄｅｒ谱。计算结果表明方柱墩群与折算圆柱墩群的群墩影响系数较为接近且随着墩间距的增加趋近于孤立墩情形。

| Abstract: | The rundom wave effect on large square caissons is studies based on spectrum analysis method. Using Bretschneider spectrum as incident wave spectrum, the grouping coefficients of square caissons are obtained for various incident wave direction and caisson spacing. It is indicated that the grouping coefficients of square caissons are a little larger than that of equivalent circular cylinders. Larger grouping effect occurs with small caisson spacing. With the increase of caisson spacing, the grouping coefficients of both square caisson and equivalent cylinder decrease and become close to each other. |
