Rubble-Mound Breakwater Stability Tests for Dos Bocas Harbor, Tabasco, Mexico

摘要

The Port of Dos Bocas is located on the Gulf Coast of Mexico within the State of Tabasco, several miles west of the Yucatan Peninsula. This site has been selected for development of an oil, industrial, and commercial port to be developed through the Mexican Oil Company (PEMEX). The initial purposes of the investigation were to determine, by two-dimensional flume tests, the stability response of three alternate armorings for the proposed breakwater and to evaluate overall performance relative to wave overtopping. Finally, based on results of the initial tests and economic considerations, the best armoring alternative would be selected, and a final recommended section would be developed and tested. The first test sections consisting of 13-Mt. Core-Locs in a water depth of 11 m and 15-Mt. Core-Locs in a water depth of 15 m proved to be stable for significant wave heights up to 7 m. These armor weights are recommended for prototype use. Also, the crownwall elevation of + 10.3 m should be adequate for significant wave heights up and including 7 m.
