장대 케이슨 방파제에 작용하는 다방향 불규칙파랑의 파력감소계수 산정

초록

By employing multi-directional random waves, a parameter controlling the force acting on a long caisson breakwater is investigated in detail. Both JONSWAP(Joint North Sea Wave Project) and asymmetric directional spectra are adopted for frequency and directional spectra. It is found that the parameter decreases as the length of caisson and the angle of main direction of incident waves increase. Furthermore, the parameter is much similar to that of regular waves as the maximum spreading parameter increases. The parameter, however, decreases as asymmetry parameter increases when the main direction of incident waves is oblique to the breakwater.
