Nghiên cứu phát triển một số kết cấu mới chống tràn cho đê sông và khả năng áp dụng tại Việt Nam

Abstract

Preventing overflow of river dike crest due to flooding is an urgent need in Viet Nam. However, the recent solution for this issuse contain many problems such as slow deployment time or material storage requirement. To overcome the above shortcomings, the research team has developed 03 new structures: (1) mobile flood protection walls made by composite-coated foam; (2) triangle flood barriers and (3) flood walls assembled by hollow-box concrete unit. These types of structures are designed in details, analyzed by numerical modeling and physical model models for optimization and then manufacture. The paper also analyzed the new properties and application conditions of each type, evaluated the efficiency compared to traditional solutions, thereby proving the feasibility of mobile flood protection solution in solving the problem of overtopping of river dikes with the technical, socio-economic conditions of Viet Nam.
