Đê cọc rỗng mặt cắt hình móng ngựa - giải pháp công nghệ mới trong bảo vệ bờ biển

Abstract

In recent years, climate change has been progressing more complicated and unpredictable, which has caused significant impacts on human life and economic production. Riverbank and coastal erosions are getting serious and increasing in riverside and coastal areas, especially in the Mekong Delta. The erosions seriously threaten the life of the people and cause huge damages to infrastructure; as a result, affect sustainable socio-economic development. Many measures and technologies have been studied to tackle the riverbank and coastal erosions. In which, offshore breakwaters have been widely studied and applied (e.g. mangrove, melaleuca, and bamboo fences; gabions and geotextile bags; detached riprap pillar breakwater, Busdaco concrete slab armouring, hollow concrete dyke, etc.). Through the analysis and evaluation of the existing measures, the paper introduces a new breakwater structure, the "Horse-hoof-shaped hollow pile dyke" for reducing wave high, promoting sediment, and protecting the coast. This is considered as an appropriate structural arrangement for coastal protection in the Mekong Delta and also the first time applied in Vietnam.
