THE CORE-LOC® ARMORING TECHNIQUE EXPERIENCE ON RECENT PROJECTS

This paper discusses recent experience with the application of the Core-Loc armor unit. Practical issues associated with implementation of CoreLoc as the armor unit on breakwaters are discussed, including stability, placement technique, packing density, the toe and the crest details. INTRODUCTION The Core-Loc armor unit is the result of many years of research at the U. S. Army Corps of Engineers (USACE) Waterways Experiment Station (WES), Coastal and Hydraulic Laboratory (CHL), (Melby and Turk 1996, 1997, Turk and Melby 1998) that has involved twoand three-dimensional hydraulic model studies, measurement of internal stresses using load cell based procedures and analysis of the distribution of stress in the unit using finite element methods. The Core-Loc unit is intended to be placed in a single, armor layer on a breakwater or revetment and may be considered as an advanced or refined version of an Accropode unit. Core-Loc units have also been designed to repair damaged Dolos breakwaters (Turk and Melby, 1997). 1 Principal, W. F.
