수리모형실험을 통해 경사식 호안 배후면 포장체 상부면에 작용하는 월파력과 하부면에 작용하는 양압력을계측하고 설계에 활용 가능한 경험식을 제안하였다. 상부구조물의 파라펫, 수심, 상대여유고 및 소파블록 피복두께조건을 다르게 실험을 수행하여 경사식 호안 상부구조물 및 배후 포장체에 작용하는 파력을 분석하였다. 이를 통해월파에 의한 파력과 양압력에 영향을 미치는 주요 상관변수를 식별하고, 포장체에 작용하는 파력을 산정할 수 있는경험식을 제안하였다.
Abstract
Physical experiments were conducted to establish an empirical formula that predicts the wave force on the upside of the pavement behind crown wall of rubble mound seawall due to wave overtopping as well as the uplift force on the downside of the pavement. The experiments were performed by different conditions of the parapet, water depth, relative freeboard, and thickness of the armour layer. Then, the wave force on the upside and downside of the pavement behind the crown wall was analyzed. The parameters that affect the wave overtopping force and the uplift force were identified and empirical formulae were suggested for evaluating the forces on the pavement.
