The new Porto Torres breakwater, Italy

摘要

Porto Torres, a busy Mediterranean industrial harbour in northern Sardinia, has been significantly enhanced by a new 2.4 km breakwater incorporating a deep-water shipping quay. The £45 million project links up with an existing 1.7 km offshore breakwater using a unique combination of rubble mound and caisson walling techniques. This Paper describes the design, model testing and construction of the project and reports on the success of its innovative wave-absorbing caisson wall design.
