This paper presents the results of wave action on walls made of closely spaced cylindrical cells 10m to 20m in diameter with both vertical and chamfered superstructures. In these tests the waves, wall dimensions, and water depth in front of the walls were subject to large-scale changes. The total wave force which acts on the cylinder with vertical superstructure is approximately equal to that acting on the corresponding length of the plane vertical wall. In case of chamfered superstructure, the total force is essentially decreased. The wave pressures are variably distributed around the cylinder surface and depend upon wave steepness. Recommendations for calculating the wave pressure against walls made of cylindrical cells with both vertical and chamfered superstructures have been worked out from the results of more than 600 experiments.
