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. In this paper, we compared the interaction between the actual quay piers structure under random wave with the JONSWAP spectrum, the wave force and diffraction wave height of the pier in the model are obey Rayleigh distribution, The coefficient of the group piers is in good agreement with the test results, which can well reflect the interaction between the group of piers. The peak values ​​of the wave crests above the hydrostatic surface are different from those of the test results in the complex layout of the pier groups.
