摘　　要：进水口体形设计是竖井式溢洪道设计关键问题之一。通过物理模型试验与数值模拟相结合的方法,对海南琼中抽水蓄能电站的竖井式溢洪道进水口进行优化设计,最终确定了在环形溢流堰堰顶增设6道不等高导流墩的布置形式。溢洪道进水口优化设计后,有效改善了堰顶流态,减小了进口库水位波动,增大泄流能力。The shape design of intake is one of key issues in the design of shaft spillway. Through the combination of physical model test and numerical simulation,the intake design of the shaft spillway in Hainan Qiongzhong Pumped-storage Power Station is optimized,and finally the scheme of six additional unequal height diversion piers are added to an the top of ring overflow weir. After the design optimization of spillway intake,the flow pattern of weir top is effectively improved,the water level fluctuation of intake is reduced,and the discharge capacity of spillway is increased.
