| Outline of Final Research Achievements |
This research was conducted to construct a three-dimensional numerical model which simultaneously simulates fluid motion and structural deformation. This numerical model will be the basis of the numerical simulation model that can deal with the interactions between wave, structure and soil foundation in future. This study discussed the local scouring of rubble mound due to tsunami over a caisson structure. SPH model, Smoothed Particle Hydrodynamics model, was employed to construct the numerical model to investigate the local scouring phenomena. The validity of the numerical model was confirmed by comparing computed results with measured ones that were obtained through hydraulic experiments. The numerical model properly simulated the scouring phenomena observed on the rubble mound. The numerical model, furthermore, applied to the field breakwater at Hosojima por. This research evaluated the stability of rubble mound and breakwater head with using this numerical model.
