십자주름 어초의 거동과 안정성에 관한 기초적 연구

Abstract

The artificial reefs are selected considering material, shape, and characteristics of the artificial reef in accordance with the purpose of use and the characteristics of the seawater area. Therefore, in order to maintain the function for the these purpose, it is necessary to examine the stability of the selected artificial reefs. In this study, artificial reef model used Cross-Wrinkle artificial reefs of 6.11×5.0×8.33(cm) scaled 1/36. And it reviewed about scour, subsidence, deposition by real sea monitoring and hydraulic model test. As Results of real sea monitoring, it appeared maximum subsidence of 20cm around Artificial reefs within no sliding and no overturn and Artificial Reefs kept stable conditions for two years. In hydraulic model test for scour and subsidence around artificial reefs, it appeared maximum 1.1cm subsidence and unstable in three cases. First case, relative depth(D/H) was less than 2.0 about both longitudinal and horizontal array of ARs. Second case, the surf parameter was less than 0.20 in longitudinal array. Third case, the surf parameter is less than 0.23 in horizontal array.
