초록
본 연구에서는 2차원 수리실험을 통해 충격파 및 비충격파 조건에서의 직립식구조물의 월파량 산정식을 제안하였으며, 연구결과는 EurOtop(2007)의 결과와 비교하였다. 특히, 최근의 월파량 산정기법의 연구동향을 고려하여 도표형태가 아닌 함수형태로 월파량 산정식을 제안하였다. 상대여유고와 무차원 월파량의 관계를 비충격파 조건은 지수함수, 충격파 조건은 거듭제곱 함수 형태로 제시하였다. 또한 경사형 상치콘크리트가 월파량에 미치는 영향계수를 제시하였다. 경사형 상치콘크리트의 설치위치가 월파량에 미치는 영향을 검토한 결과에 의하면 설치위치에 따른 차이는 크지 않은 것으로 나타났다.
Abstract
In this study, two dimensional wave overtopping tests for vertical wall were performed and overtopping formulas were suggested for impulsive and non-impulsive wave conditions. The test results from this study were compared with those from EurOtop(2007). The wave overtopping formulas were derived and suggested considering the recent research trends, while the existing method used the diagram. The wave overtopping formulas have the form of exponential and power functions using non-dimensional variables for wave overtopping and freeboard heights for non-impulsive and impulsive condition, respectively. The wave overtopping formula and effective parameters for inclined superstructure were also suggested. It is analyzed that the locations of inclined superstructure do not have the significant effects on wave overtopping, that is, the wave overtopping rate were almost same for each locations.
