Abstract
본 논문에서는 부유 플랩형 고조방파제의 응답특성에 대해서 연구하였다. 효율적인 연구를 위하여 파동장은 선형 포텐셜 이론을 적용하여 모형화하였으며, 구조물의 운동은 Newton의 운동 제2법칙을 사용하여 나타내었다. 유체 영역은 통상의 2차 보간함수를 갖는 등매개변수요소로 모형화하였으며, 방사경계조건에 접하는 외부 영역은 무한요소로 처리하였다. 수리실험결과와의 비교를 통하여 수립된 수치모델의 타당성을 입증하였으며, 개발된 수치모델을 이용하여 마산만에 부유 플랩형 고조방파제 적용가능성에 대해서 살펴보았다.



In this paper, wave responses of buoyant flap-typed storm surge barriers was studied numerically. Wave motions were modeled by using a linear potential wave theory, and behaviors of structures were represented as a Newton's 2nd law of motion. The near field region of the fluid was discretized as conventional quadratic iso-parametric elements, while the far field was modeled as infinite elements. Comparisons with the results from hydraulic model tests show that the present model gives good results. By using the model, the applicability of a buoyant flap-typed storm surge barrier in Masan bay was investigated considering field environmental conditions.
