Nghiên cứu áp dụng tính toán cọc chịu tải trọng ngang ở khu vực đồng bằng sông Cửu Long phục vụ cho công tác thiết kế - xây dựng kè ven sông ở kênh Xáng Xà No - tỉnh Hậu Giang

Abstract

n Vietnamese current situation of economic development, along with the demand for developing transportation infrastructure for external relations, it is crucial to invest in domestic traffic network throughout provinces all over the country. In which, Southern areas of Mekong and Ho Chi Minh City obtain routes beside interlaced rivers with a large majority of weak ground base. Flood and erosion annually cause damages for people and property of state and people living near such areas. At present, there have been a number of solutions to prevent erosion and effectively protect the structures including sheet pile wall and prestressed concrete, etc. However, such measures requires relatively high costs. Meanwhile, Vietnam is still in a developing period with limited budget, thus requesting the state to pay more attention to budget savings. For such reasons, in this research, the author will present the method of “Reinforced concrete piles combining with reinfoced concrete sheet” to preserve and protect the ground behind the wall. Such concrete sheets are responsible for preventing surface layer from sliding and ensure to connect the piles via pilework. This is one of the most effective method in saving costs in comparison with sheet pile wall and prestressed concrete as mentioned. Therefore, the research on “Study of lateral loaded piles in weak ground in Vi Thanh Town, Hau Giang Province” is put the highest priority by the agency concerned.
