영문 초록

The sliding stability of monolithic vertical caisson of composite breakwaters is quantitatively analyzed by using a reliability model, FMA of Level Ⅱ, in order to study the variation of sliding failure of caisson due to the occurrence of extreme waves exceeded deepwater design wave. The reliability index and several parameters in the wave pressure formula are inter-related to find out the effects of extreme wave exceeded design wave on the sliding failure of vertical monolithic caisson. The sliding failure of caisson seems to be largely increased as the heights and periods of extreme waves exceeded design wave increase, also depends directly on the water depth in front of the composite breakwaters. From the numerical simulations carried out with several kinds of extreme waves exceeded design wave which are assumed to be occurred during the service periods of breakwater, it is found that the effects of the wave height on the sliding failure of caisson may be more dominant than those of wave periods and angles of wave incidence.
