Abstract

The stability of low-crested rubble mound structures has been treated before by various researchers. In the first phase of this study two data sets from different laboratories were combined to one homogeneous data set. Re-analysis of these data resulted in a design diagramme for the stability of the seaward side, the crest, the rear and the total armour layer of the structure. Secondly, model tests were performed on carefully selected rock with different rock shapes (angular, flat and rounded) and different gradings, all for a low-crested structure. Results show that the differences between the various rock types were small, especially for the start of damage. The influence of the length/thickness ratio showed even no infuence at all which means that the sometimes strict requirements in construction may be released.
