Description: Technical note
Introduction: The CORE-LOC series of armor units, recently developed by the Corps of Engineers, provides optimized concrete armor units for protecting all coastal structures. The unit was designed to be placed in a single layer on either steep or shallow slopes. The unit shape was designed to have much lower stresses than existing slender armor units and to produce an armor layer with very little or no rocking units during design conditions. The unit was designed to also be used as a repair unit for dolos slopes because the dolos shape is overly slender producing high stresses in the interior of the unit. Also, the impact stresses due to rocking have been found to be very high in dolos armor units and dolos layers typically have between 1 percent to 2 percent of the on-slope units rocking, even for small wave conditions.
