防波堤의 任意 配置에 對한 波浪 廻折 = Wave diffractions for Arbitrary Disposition of Breakwaters

다국어 초록 (Multilingual Abstract)

In harbor design, it is a necessary condition to retain calmness inside a harbor. For this purpose, breakwaters are disposed as exterior structures against incident waves. There are cases that necessitate main and auxiliary breakwaters according to frequent directions of incident waves. In these cases, harbor entrances have various geometric shapes in horizontal plane. In the program developed here, harbor entrances are classified into six different cases by the disposition of breakwaters and the attack angle of incident waves. For each case, the diffraction phenomena inside and around harbor entrance are analysed by superposing the solutions of Sommerfeld's. The method gives fairly good results compared with those reported before, and also is proved to be computationally very efficient. Therefore, the method may be applicable to the preliminary design of breakwater dispositions, and also the program can be used as the basic subroutine in the calculation of wave height distributions inside a harbor with reflected waves.
