DEVELOPMENT OF PREDICTING MOTION OF FLOATING CAISSON UNDER REGULAR AND IRREGULAR WAVES

Breakwaters for outer harbor facilities are considerably affected by wave conditions, rendering the control of caisson motion difficult. Its during breakwater installation is important to improve its operational efficiency and safety. In recent years, has been studied using 3D solid-gas-liquid three-phase simulations. Nakamura et al. (2021) investigated dynamic characteristics floating caissons under regular irregular waves. Takagi sway contact with mounds when bottom clearance was changed demonstrated validity their numerical method. However, due inevitable scale effects small-scale experiments simulations, these studies require examination at a large scale. this study, simulation developed Arikawa (2009) used investigate life-sized waves case conducted Port Kochi (Ishimi 1996).
