Thiết lập mô hình thí nghiệm nghiên cứu sóng tràn qua đê biển có kết cấu hình trụ rỗng tại đỉnh ở đồng bằng sông Cửu Long

Abstract

There are a lot of coastal defence constructions along our country coastline in form of sea dike combined with a vertical wall to reduce overtopping discharge and the height of dikes. Vertical wall structures often create high reflection waves and forces on structures are also very big. Because of these reasons, author and others in a research group of Hydraulic Construction Institute had used a new structure called quarter circular breakwater to replace the vertical walls. Some of interaction characteristics between wave and structure were studied, especially in overtopping wave. The quarter circular breakwater, which was placed at the crest of dikes, has perforated at the sea side with different ratios. It can be made by reinforced concrete or high strength non – metallic as well as other new materials.
