Wave Structure Interaction by Installation of New Circular Caissons on Old Circular Caisson Breakwater

摘要

The design and the construction are carried out by installation of new caissons on the back or the front of old caissons to increase the stability of old caisson breakwater.In this study,we use the eigenfunction expansion method to analyze the effects of wave structure interaction when new circular caissons are installed on the back or the front of old caissons.The comparison of numerical results between present method and Williams and Li is made,and the wave force and the wave run-up acting on each circular caisson are calculated for various parameters by considering the wave structure interaction.
