| Abstract: | The dam of Changtang Hydropower Station,with the maximum height being 88 m,is a roller compacted concrete double-curvature arch dam,whose type for flood discharge and energy dissipation is three top holes plus one medium outlet.Here,its layout scheme for flood discharge and energy dissipation and the optimized layout of outlet structures are introduced in detail.The conical buckets are used in three overflow top holes in order to slove such the problems as the centripetal flow,energy dissipation and erosion control during flood discharge in Changtang Hydropower Station. |
