Abstract
Damage level of coastal structures has been scaled up according to the increase of wave height and duration of a storm due to the global climate change. Therefore the design criteria for a new breakwater is being intensified and structural strengthening works are being also conducted for securing the existing breakwaters. Recently, an interlocking caisson-type breakwater has gained much attention to enhance the stability of the conventional breakwaters. In this study, the dispersion characteristic of wave forces using an interlocking system which connects the upper part of caisson with cables in the normal direction of a breakwater was investigated. From numerical analyses, the higher wave forces are transmitted through the interlocking cables as the angle of an incident wave is larger, and the maximum allowable wave force was capable to be increased by sharing the wave forces with the adjacent caissons. Further, it was also found that the larger the stiffness of the interlocking cable makes the larger wave dispersion effect.strengthening works are being also conducted for securing the existing breakwaters.
