Abstract

This study reports physical experiment campaign to measure horizontal wave pressure acting on a solid caisson that is protected with double-layer Tetrapods and core-layer of rubble stones. The main focus of this study was to evaluate the effects of crest level of the armor layers on the measured wave pressures. The measurements were conducted with four different models in terms of the coverage of the front face of the caisson: no coverage, full coverage up to the crest of the caisson, and two different partial coverages where the crest level of the armor layers were lower than the crest of the caisson. The wave pressures above the still water level showed significant discrepancy depending on different armor coverages, especially for the caisson that are partially protected by armor blocks. It seemed that impulsive loadings acted at times on the top exposed part of the caisson if the caisson is imperfectly protected by armor blocks.
