摘　　要：长塘水电站大坝为碾压混凝土双曲拱坝,最大坝高88 m,采用3表孔+1中孔泄洪消能方式。本文介绍了泄洪消能布置方案的研究,泄水建筑物体型优化,以及3个溢流表孔采用锥形体鼻坎体型,解决长塘泄洪中出现的向心水流和消能防冲问题的研究成果。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.
