Abstract

To repair armor blocks damaged by high waves, an expensive in-water repair work using a crane barge must be done. A wire connection with among blocks can be effective to save maintenance cost. But, to conduct hydraulic experiment of among blocks connected by wire is considerably difficult because of a lack of a physical model of wire satisfying dynamic similarity. In the present study, simple wire model based on the distinct element method has been developed to investigate the effect of wire connection of armor blocks as a resistance of damage under high waves. Validation of developed wire model is conducted by comparing model predictions with field observations.
