摘要
本文基于二维源分布法给出了求解任意截面群墩结构波浪荷载的数值计算方法。该方法与Isaacson的孤立方墩试验结果符合较好,并与Spring和Monkmeyer的圆形群墩理论解相一致。文中对2个方形等截面群墩在不同kb时的群墩系数进行了讨论,并比较了折算圆群墩的理论群墩系数。探讨了群墩截面几何形状不同与群墩间相互影响的关系,得到了一些对海岸及近海工程中群墩结构设计有意义的成果。
A numerical method for determining wave forces on large vertical caissons of arbitrary-section is described based on two-dimensional wave source representation method.For an isolated square caisson,the numerical predictions agree reasonably well with the results from Isaacson's experiment.Computer results for a pair of circular cylinders conforms to the closed-form solution of Spring and Monkmeyer.Interaction of two square caissons with various kb is discussed and compared with equivalent circular-section caissons.The results obtained in the paper are expected to be useful in coastal and offshore engineering.
