功果桥水电站泄洪消能建筑物设计

功果桥水电站采用坝身表孔和底孔联合泄洪方式。表孔采用X形宽尾墩+台阶式溢流坝面+戽式消力池联合消能工,底孔采用贴角导向挑流鼻坎消能工,该消能工既能高效解决泄洪消能问题、减轻泄洪雾化对边坡稳定的影响,又能较好地适应碾压混凝土分层、通仓、快速浇筑的特点,对加快碾压混凝土施工、节省工程量和提高工程效益具有积极意义。

Design of Energy Dissipation Structures for Flood Discharge,Gongguoqiao Hydropower Project

The combined energy dissipation of flood discharge by surface outlet and bottom outlet in dam body is applied in Gongguoqiao Hydmpower Project. The combined energy dissipator consisting of X-shaped flaring pier, stop-typa overflow dam surface and bucket still- ing basin is applied in the surface outlet. The energy dissipator of flip bucket with fillet and ~tion guidance is applied in the bottom outlet. This energy dissipator can dissipate flood-discharge energy in a high efficiency and mitigate impacts on the slope stability by the flcod-discharge atomization as well as well gear with lift division, full block and quick placement of miler compact concrete. It is meaningful to speed up RCC placement, reduce work quantity and improve engineering benefits.
