摘　　要：本文对随机波浪作用下某实际群墩码头结构的相互影响进行了数模与试验的比较.入射波谱采用JONSWAP谱,数模中假定墩柱波浪力及绕射波高服从Rayleigh分布,数模得到的群墩系数与试验结果符合较好,能较好地反映出群墩间的相互影响、静水面以上的波面峰值与试验结果在墩群布置复杂的区域存在一定的差别.Numerical results of random wave actions on pier group are compared with experiments , illustrated by an engineering project. JONSWAP spectrum is used as incident wave spectrum. Wave force on each pier and diffracted wave height are assumed to obey Rayleigh's distribution. It is shown that the numerical results of pier group coefficients agree well with experiments. Interactions between pier groups in random wave are predicted well by numerical model, although there exist some difference in maximum wave crest between numerical computation and experiments in the region where the arrangement of piers is complicated.
