摘　　要：斑竹园水电站是典型的山区河流低水头的小水电站,泄洪单宽流量大,泄洪消能任务较重。通过整体水工模型试验,对泄洪能力、水流流态、流速分布、消力池消能效果、拦沙排沙方案及电站尾水渠水位波动进行系统研究,验证和优化了设计,提出了两级复式消力池及合理的泄洪运行方案,为工程决策提供了科学依据,可为类似的山区小水电消能设计提供参考。Banzhuyuan Hydropower Station is a typical low-head small station in mountainous river.The inflow rate against unit width is so large that flood release and energy dissipation are rather difficult.Through the whole hydraulic model test,the article systematically studies the capability of flood release,water flow regime,flow velocity distribution,energy dissipation effect of the stilling basin,sediment flushing program and water level fluctuation in tailrace to verify and optimize the original design,and presents the two-stage compound stilling basin and rational spillway operation schemes.The study results provide a scientific basis of decision-making for Banzhuyuan Hydropower Station,and afford reference for similar small hydropower projects in mountainous area.
