Abstract

Vietnam - a country which has 3260km coastline long, 89 estuaries and more than 300 islands. At present, there are many protective structures with inclined roof shapes combined with low crest walls, vertical walls with bullnose to reduce overtopping flow and wave pressure impacting the dyke. However, top and vertical walls create the great reflected waves and the force on the structure. From the current situation as well as the above urgent requirements, the research team of the National Key Laboratory of River and Marine Dynamism has proposed a hollow wall structure with a wave-attenuated nose in a shore protection project. Hollow-wall structures with wave-attenuated jets have perforated corrugated front ends, wave dissipation chamber with different proportions of holes and chambers size, is made by reinforced concrete materials or some new materials.
