The demand for large discharge sluices in Viet Nam is increasing as the constructions of small river barriers show their restrictions in flooding and salt intrusion protection. The main objective of this study is therefore to research an appropriate design for the sluice structure type that can be applied in Vung Tau Go Cong, which is the largest project of discharge sluice in Viet Nam so far. From the literature review, it can be seen that in the Netherlands, several units of sluice caisson have been applied but their main function was only to permanently close the basin, while in Viet Nam only a single caisson is applied as small river barriers. It is to say that a large discharge sluice with several units of caisson has never been built so far. In contrast with this type of structure, most of discharge sluices and barriers in the world have been build according to the “pier structure type”. In the Netherlands piers and bottom slabs are normally placed on batter pile foundations. Meanwhile in Viet Nam, piers are often placed on vertical pile foundations and a bottom slab is replaced by supporting beams. Because of both “proven structure”- caisson and pier have their own strong and weak points, by combining the best features of these “proven technologies” of the Netherlands and Viet Nam; two appropriate structure types were designed and the critical concerns related to them were checked. It is concluded that the caisson and pier sluice structure are feasible solutions for the discharge sluice at Vung Tau Go cong. It can be also considered as an innovative structure for larger discharge sluice.
