【 摘 要 】

A design algorithm for the optimal cost effective rubble mound structures is developed considering extreme wave statistics and wave control functions as well as the stability under the irregular wave attack. In the algorithm, the conventional deterministic design method and the optimization technique, SUMT (Sequential Unconstrained Minimization Techniques) are used to evaluate the minimum cross section of the structure. The applicabilty and design sensitivity of the algorithm is examined using experimental data on stability, run-up / overtopping and reflection under the various irregular waves that have different wave grouping characteristics. The field conditions not only the construction method but also the costs can be introduced in the cost estimation subroutine.
