Abstract
The slender, complex types of armour units, such as Tetrapods and Dolosse are
widely used for rubble mound breakwaters. Many of the recent failures of such
structures were caused by unforeseen early breakage of the units, thus revealing
an in balance between the strength (structural integrity) of the units and the
hydraulic stability (resistance to displacements) of the armour layers. Breakage
is caused by stresses from static, pulsating and impact loads. Impact load generated stresses are difficult to investigate due to non-linear scaling laws. The
paper describes a method by which impact loads on. slender armour units can
be studied. by load-cell technique. Moreover, the paper presents DoJos design
diagrams for the prediction of both breakage and hydraulic stability
