【Abstract】 The irregular wave forces on the piles of small diameter are experimentally investigated. The total in-line forces on single vertical pile and on each pile in- array in irregular waves are. measured. For single pile, the relation ships betw- een CD,CMand K-C numder are determined with the best least-square method in time domain.In the case of two piles in the side-by-side arrangement and the tandem arrangement,a grouping-pile factor, Kc, is used to consider the inter- ference between two piles. Based on the experiments,the plots of Ko versus K-C number and the relative distance, 1/D, are given.更多还原
