摘　　要：通过对新疆小石峡水电站表孔溢洪道的模型试验研究,优化了溢洪道进口段,改善了进口流态;提出在溢洪道消力池内布设趾墩—消力墩—尾坎的修改方案,试验结果表明,修改方案有效的改善了池内水流流态,同时缩短了池长、降低了池深,提高了消能效果,并且消力池内各项水力指标满足设计要求。试验成果对于工程设计具有借鉴意义。Through model test research for surface orifice spillway of Xiaoshixia hydropower station in Xinjiang,we optimize the spillway entrance and improve the intake flow patterns;propose the revising scheme to set up toe pier-stilling pier-tail bank in spillway＇s stilling pool.The test results show that revising scheme improves the flow pattern effectively in spillway stilling pool,while reducing the pool length and depth,increasing efficiency of energy dissipation,and hydraulic targets in stilling pool satisfy the design requirements.So test results can provide a reference for engineering design.
