| 内容記述 | In Japan, not only breakwaters but also seawalls inside surf zone are normally covered with wave-dissipating concrete blocks in front of the vertical wall. The placement of wave-dissipating concrete blocks is helpful to reduce wave overtopping, transmitted waves and wave pressure acting on the wall. The vertical structure with a detached mound made of wave-dissipating concrete blocks (hereinafter referred to as “the detached type”) is a kind of structure. It is basically pointed out that the detached type is more effective than the conventional type in both wave control function and stability. But the values of wave overtopping rate, wave transmission coefficient and time-averaged water elevations in wave chamber on the detached type may not be estimated quantitatively. Moreover the wave pressure acting on the wall is not proved for steep bottom slope. Therefore, we have carried out the experiment to examine the performance of the detached type using 2 models for bottom slope of 1/10 in a long wave flume. The volume of fluid method is employed in numerical simulation. As a result of both physical model test and numerical simulation, the values of wave overtopping rate, wave transmission coefficient and time-averaged water elevations are confirmed for slope of 1/10. It is also found out that the wave pressure acting on the wall shows impulsive wave pressure at around still water level. | |||||
