【 摘 要 】

A calculation method is presented to determine the strength of a block revetment against wave loading. The critical loading on such a revetment is present during wave run-down when still relatively high pore pressures exist in the filter layer and the blocks can be pushed out of the revetment. The strength of placed block revetments against this loading is not only composed of the weight of the blocks, but also of the friction and clamping forces. Friction and clamping forces are incorporated in a calculation method, using a simplified model that takes into account the horizontal and vertical forces separately. Example calculations show the forces that can be expected in such a cover layer.
