摘要
Abstract
As locating in a deep valley, the spillway of Nuozhadu Hydropower Station has a maximum flood head of 182 m, a maximum flood discharge of 31 318 m35 and a flood power of 55 860 MW. All of them rank firsts in China at percent, so the energy dissipation of Hood discharge is very important for [his project. Some layout programs of spillway structure are compared in the stage of ( feasibility study, and detailed studies are also conducted in the stage of design tender. Based on overall hydraulic model tests and sonnc specific researches on spillway structure, aeration to prevent cavitations, protection on banks and no protection on river bottom and the atamiztion 2ation of dlscharged water, the large river-bank spillway for this project are designed. The stilling pond arranged on the downstream of flip bucket has effectively solved the problem of energy dissipation.关键词
