- Abstract
As a common spillway type in China, weir is also widely used in water releasing structures of overseas HPP. In order to guide the hydraulic design of spillway in overseas hydropower projects, the paper compared the provisions of the “Design of Small Dams” issued by US Bureau of Reclamation and “Design Specification for River-Bank Spillway” DL/T 5166-2002 issued by China State Economic and Trade Commission on hydraulic calculations and analyzed the differences in calculation formulas, calculation parameters selection, etc. Meanwhile, by the practical use in Soubre HPP in Cte d’Ivoire and Xe lanong-1 HPP in Laos, the paper respectively compared the relationship between theoretical calculations and hydraulic model test results on discharge capacity under low weir and high weir when the front of the weir was vertical. About low weir, the research shows that the theoretical value of the discharge capacity of the “Design of Small Dams” is closer to the hydraulic model test results. About high weir, the theoretical value of the “Design of Small Dams” is closer to the hydraulic model test results when the discharge capacity is relatively small, while the theoretical value of “Design Specification for River-Bank Spillway” is closer to the hydraulic model test results when the discharge capacity is relatively larger.
