Deterministic computer-aided optimum design of rock rubble-mound breakwater cross-sections
AbstractThe deterministic computation of the optimum rubble-mound breakwater cross-section is executed on a micro-computer. Moreover the application of CAD-software within the optimization process is examined.The quarry production, divided into a number of categories, and long-term distributions of deep water wave heights and water levels, form the basis of the computation. Deep water wave heights are converted to wave heights at site. A set of alternative cross-sections is computed based on both functional performance criteria, and Van der Meer's stability formulae for statically stable structures. Construction costs and maintenance costs are determined of each alternative. The optimum is derived by minimizing the sum of the construction costs and maintenance costs. Moreover, the programme provides means to economize the use of the quarry.At this stage the computer programme is useful for feasibility studies of harbour protection or coastal protection in regions, where use can be made of a quarry in the neighbourhood of the project site. Use of concrete armor units is excluded in this study. Concrete armor units are excluded sofar, but will be implemented in the next stage.
