| To reduce the construction costs of seawalls and lower the environmental impact of construction、 we have been working to develop a new high mound composite structure. Several studies have focused on the hydraulic characteristics of high mound composite seawall; however sufficient examination has not been carried out on the oblique wave conditions. Three-dimensional hydraulic model experiments were conducted to investigate the wave force characteristics and wave overtopping characteristics under oblique wave conditions. Based on the phase difference of impulsive wave force acting on upright sections、 wave force reduction rate for oblique waves were proposed. Furthermore、 influence of incident wave angle on wave overtopping rate and wave splash height were studied. |
