Abstract
It is needed the introduction of a new wave dispersion relationship considering the condition of seabed to examine closely the interaction between wave and seabed. In this study, a wave dispersion relationship is newly developed considering the condition of seabed such as permeability and displacement. Wave damping rates are compared and analysed according to the various soil parameters such as seabed soil thickness, elastic modulus, saturation, permeability, and porosity.
파랑과 해저지반의 상호작용을 규명하기 위해서는 우선 해저면의 경계조건을 고려한 새로운 분산관계식의 도입이 필요하다. 본 연구에서는 깊이가 유한한 해저지반의 투수성 및 변위를 고려한 새로운 분산관계식을 유도하였으며, 해저지반의 두께, 탄성계수, 포화도, 투수계수, 간극률 등 다양한 지반상수의 변화에 따른 파랑 감쇠율을 비교 검토하였다.
