摘　　要：文中针对石头峡水电站"龙抬头"式泄洪洞进行了模型试验研究,指出原设计体型存在的问题,对泄洪洞"龙抬头"段、出口挑坎体型进行了优化,并进行了试验验证。优化后泄洪洞水流流态较好,壁面未产生过大负压,出口水流归槽良好。According to the model test study on the spillway tunnel with inlet raised of Shitouxia hydropower station, the existed problems in the original design shape are pointed out. the shapes of flip bucket of spillway tunnel with inlet raised and outlet are optimized and verified. The water flow pattern of the optimized spillway is better, no excessive negative pressure on the wall and the outlet flow coming into main channel is good.inlet tower of spillway tunnel.
