Simulation of Armor Blocks In Front of Caisson Breakwater By DEM-MPS Hybrid Model

At a low crown caisson seawall with a large-size wave overtopping drainage, the pick-up of blocks on a caisson mound is one of the important issues in the design of seawall. Therefore, in this study, a simulation by the DEM-MPS hybrid model is carried out. In this model, fluid is calculated based on the MPS method and blocks are tracked by the DEM. In a calculated result, blocks around the top of mound slope are picked up. This fact agrees with the hydraulic experiment.
