摘　　要：福生水电站采用底流式消力池消能。其特点是水头低、流量大,是典型的低佛氏数消能,加之自由溢流坝、翻板门泄水闸、冲沙闸联合泄洪,因此翻板门运行工况有无限制、泄流能力及消能效果能否满足设计要求就需要进行深入研究。经过断面模型试验,优化了辅助消能工布置,改善了流态,缩短了池长,提出了翻板门小洪水工况下的不稳定流范围,为设计提供了依据。The Fusheng hydropower station adopts the underflow stilling basin to dissipate the energy.It is the typical low Froude number energy dissipation with the characteristics of low water head and large water flow.Based on the combined flood discharge with the free overflow dam,flap gates sluice and flushing sluice,the operation restriction of flap gates,the discharge capacity and energy dissipation effect are needed to research deeply.Through the cross-section model test,the layout of auxiliary energy dissipation is optimized,the flow pattern is improved,the pool length is shorted,the unstable flow range under the condition of flap gates small flood is made,which provide the basis for the design.
