【 摘 要 】
In this study, the modeling of damage progression of rubble mound revetment and the performance evaluation based on laboratory experiments and numerical computations are performed. The model profiles for the damaged revetment are made on the basis of the experiments to measure the profile change. The model profiles corresponding to the degree of damage are determined by using some empirical equations that are related to the deformation quantity of the revetment. To examine the change of performance due to damage progression, the model profiles are also used in other experiments and numerical computations. The reflection coefficient and overtopping rate are taken as performance indices. The measured reflection coefficient shows a tendency to decrease, while the overtopping rate increases more than twice as much as that of the initial profile with damage progression of the revetment. The computed reflection coefficient and overtopping rate agree reasonably well with the experimental data.
