Development of Design Methods for Breakwater Armour Units.

摘要

The research has been completed in accordance with the research proposal dated 1. May 1989. The research program contained the following activities: (1) Coordination of the armour unit research at the Hydraulics Laboratory of the University of Aalborg (AHL) and CERC; (2) Investigation of static load in tests on sloping ramps. Comparison of results from 200 kg concrete units (AHL) with results from 200 g units made of concrete (AHL) and epoxy material (CERC) with the objective of studying size scale effects and surface roughness scale effects; (3) Investigation of the possibility of measuring impact loads in model tests with the small scale units (200 g); (4) Wave tank parametric studies of the dependence of the armour unit stresses on sea state parameters and the geometry of the breakwater. The wave tank tests are coordinated with tests at CERC, cf. item 1; and (5) Establishment of design diagrams including proposal for improvement of Dolose. (KR)
