Abstract
As global warming continues, the ratio of intense typhoon is increased while the frequency of typhoon is reduced. High waves which are generated by an intense typhoon are expected to be higher than design waves. In order to cope with such environmental changes efficiently, researches of long structures have been attempted. When oblique incident waves propagte, the wave force acting on the long structure can be reduced due to the phase different of hydrodynamic pressures. Interlocking caisson breakwaters can be categorized as a concave-convex, a key block, a cable, and a filling material. We carry out the hydraulic experiment with regular waves in a wave basin for the stability comparison of open-cell caisson breakwaters and conventional caisson breakwaters. The open-cell caisson breakwater is one of interlocking caisson breakwaters of the filling material. Gravels as the filling material are filled out in open-cells. As a result,the open-cell caisson has high stability about 10% comparing with the conventional caisson. Because the frictional resistance force by gravels in the open-cell is increased even though the incident wave propagates to the normal direction of the breakwater in which the pressure acting on the breakwater has no phase difference.nvironmental changes efficiently, researches of long structures have been attempted.
