PAPER NO: 157 THE CORE-LOC™ ARMOURING TECHNIQUE EXPERIENCE ON EIGHT RECENT PROJECTS

The Core-Loc™ armour unit is the result of many years of research at the U.S. Army Corps of Engineers Waterways Experiment Station (WES), Coastal and Hydraulic Laboratory (CHL). (Melby and Turk 1996. 1997. Turk and Melby 1998) that has involved two and three-dimensional hydraulic model studies, definition of internal stresses using load cell based procedures and defining the distribution of stress in the unit using finite element methods.

The Core-Loc™ unit is intended to be placed in a single Dhalkut, Oman layer in an armour layer on a breakwater or revetment and may be considered as an advanced or refined • Fishing Harbour version of an Accropode® unit. Core-Loc units have • 46 700 cubic meters of concrete also been designed to repair damaged Dolos • 7 200 units of 3.9, 6.75 and 9.0 cubic meters breakwaters (Turk and Melby, 1997).
