영문 초록

In this study, the hydraulic model tests for the single chamber perforated wall caisson were performed to investigate the reflection coefficients according to the slit shapes. The perforated wall with vertical and horizontal slits was applied to the tests. The random waves were used for the test by using Bretschneider-Mitsuyasu frequency spectrum. The similar reflection coefficients were measured in the vertical and horizontal slit caisson within a similar perforation ratio and area. The reflection coefficient according to relative slit length(S/Hs) was analyzed and the minimum reflection coefficients were measured in relatively small S/Hs (=2.7). The results from horizontal slits showed similar trends with those from the vertical slit perforated wall.
