Abstract
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.
Highlights
The performance-based design of coastal structures is recently becoming standard
The reflection coefficient and overtopping rate are taken as performance indices, and laboratory experiments and numerical computations using the model profiles are conducted to investigate the variations of the indices due to the damage progression of the revetment
A series of laboratory experiments were conducted in ten wave flumes to investigate the profile change due to damage progression of the rubble mound revetments under some conditions
Summary
The performance-based design of coastal structures is recently becoming standard. It is necessary that the relation between the damage of structure and the performance degradation is evaluated to apply the performance-based design. We perform the modeling of damage progression of rubble mound revetment based on the experimental data of damaged profiles. The model profiles will contribute to the performance evaluation of the damaged revetment through the use of them in laboratory experiments and numerical computations as Ota et al (2010) mentioned. The reflection coefficient and overtopping rate are taken as performance indices, and laboratory experiments and numerical computations using the model profiles are conducted to investigate the variations of the indices due to the damage progression of the revetment
