The present study aims to give general hints about hydrodynamic interactions for water wavediffraction on a super large floating structure composed of a large number of box-shaped modules withmany small gaps in between.And meanwhile,it also aims to seek for an effective way to take the gap influ-ence into consideration without numerical difficulties existing in conventional methods.An asymptotic ma-tching technique is exploited by virtue of the smallness of gaps.Formal potential solutions are establishedfor the near field around the gap ends and the far field away from gap ends,respectively,and theunknowns in those solutions are uniquely determined by asymptotic matching.The eigen-function expan-sion method is used for the outer far field and a series of pulsating sources at each gap end is introduced tosimulate the gap influence.Strong hydrodynamic interaction is observed and a new resonant phenomenon,the mechanism of which differs absolutely from any known ones,is revealed in the present study.Sharppea
