본연구에서 Penney and Price(1952) 의해석해를사용하여반무한방파제, 양익방파제등에서발생하는파랑의회절및다중반사현상에대한해석해를구하였다. 구조물에서의반사현상을양익방파제를지나는회절현상으로간주하여방파제에서발생하는단일반사및다중반사현상을규명하였다. 이를바탕으로방파제의위치와입사파랑의각도에따라다른경우에도해석해를구할수있다. 이러한해석해는국내의항만실무자들에게회절및다중반사현상에대한이해를도울수있을것이며, 실무의해안및항만구조물설계시에사용되는수치프로그램들의정확도를판단할수있는비교대상으로사용될수있으리라판단된다.
Abstract
In this study, we get an analytical solution for the diffraction and multi-reflection around a semi-analytical solutions for single- and multi-reflections around the breakwaters by assuming that the reflected wavesare regarded to be those diffracting through a breakwater gap. On the basis of these solutions, it is possible tounderstand the wave diffraction with diferent cases of incident wave direction and breakwater layout. Thesesolutions may help harbor engineers to understand the phenomena of diffraction and multi-reflections around thebreakwaters. These solutions may also be used to evaluate the applicability of wave transformation models whichare used in designing coastal structures.
