PLEA FOR THE PLACEMENT OF ARMOUR BLOCKS IN ORDERLY PATTERNS

Fernando Vasco Costa

Abstract


Just by placing hollow blocks in orderly patterns, all in the same direction and well interlocked among themselves, not only will their resistance against localized wave actions be greatly increased, but their resistance will vary little from one block to another. Furthermore, the risks of their breakage due to "rocking motions" and of the rapid spreading of damage once initiated, will be essentially eliminated. To render possible the placement of blocks under the water surface in predetermined positions, in the presence of waves and currents, the blocks should be suspended simultaneously from three or four inclined cables.
