洛古水电站泄洪消能建筑物设计

洛古水电站采用3表孔集中布置、2底孔分列两侧的孔口布置方案，表孔采用“x”型宽尾墩＋WES曲线＋台阶堰面＋消力池的消能方式，底孔采用坝内有压式流道＋反弧＋消力池的消能方式，表底孔共用1个消力池。通过模型试验验证，洛古水电站泄洪消能建筑物的布置型式很好地适应了坝址的地形地质条件，能够满足泄洪消能要求，消能效果良好。

Design of Energy Dissipation Structures,Luogu Hydropower Project

In Luogu Hydropower Project, three surface outlets are arranged centrally and two bottom outlets on both sides. The surface outlet is with the energy dissipation structure consisting of Xtype flaring pier, WES curve, step weir surface and stilling basin. The bot tom outlet is with the energy dissipation structure consisting of pressure chute within dam, ogee and stilling basin. Both surface and bot tom outlets share the same stilling basin. Verified by model test, the layout of the energy dissipation structures of Luogu Hydropower Pro ject well accommodate both the geological and topographical conditions at the dam site, satisfy requirements of flood discharge and energy dissipation, and achieve excellent energy dissipation.
