摘　　要：针对巴山水电站溢洪道具有泄量大、水头高、下游消能区地质条件差等特点,通过1∶70整体模型试验对溢洪道的挑流消能防冲布置及消能形式进行了4个方案的试验研究。结果表明:优化方案四的挑流鼻坎形式较合理地解决了下游消能困难的缺点,基本能够满足工程实际的需要。Aiming at the characteristics of the Bashan hydropower station＇s spillway such as large flood discharges,high head,bad engineering geology of downstream energy dissipation area,the experimental research of four projects was proceeded by 1∶70 integral model test to the ski-jump energy dissipation,scour protection arrangement and energy dissipation type of the spillway.According to the results,the flip bucket type of the fourth optimal project was more reasonable to solve the problem of the difficult downstream energy dissipation,which could satisfy the demand of the practical engineering.
