摘　　要：鲁地拉水电站采用五表孔集中布置、两底孔分列两侧的孔口布置方案,表孔采用"X"型宽尾墩+台阶堰面+戽式消力池的联合消能方式,是目前中国采用这种联合消能型式的工程中坝高最大的水电站;底孔采用长泄道挑流消能方式。通过模型试验验证,鲁地拉泄洪建筑物的布置型式较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。The scheme is arranged for Ludila hydropower project, with concentrated five surface orifices and two bootom oulets at both sides. The compound energy dissipator is applied for surface orifices, with ＂X＂ shaped flaring pier plus step weir surface plus bucket basin, and is adopted for the project with the highest dam in China for the time being. The long - sluicing ski jump energy dissipation is used for bottom outlets. Through hydraulic model tests, the arrangement of structures adapts to landform and geological conditions, and can satisfy the requirements of energy dissipator for flood discharge, which has achieved good effect of energy dissipator.
