结合观音岩水电站泄水建筑物的关键水力学问题，阐述了双泄中孔掺气减蚀试验、明渠溢流坝消力池体形优化试验、岸边溢洪道取消中隔墙试验的研究成果。研究结果表明：双泄中孔泄槽底板掺气减蚀效果总体较好；明渠溢流坝新型跌坎渐扩式消力池消能充分，临底水力学参数较小，应加强底板关键区域的结构稳定设计；岸边溢洪道取消中隔墙后基本不影响下游河道的消能防冲效果，但是减弱了工程运行的灵活性，运行宜同时参照工程调度试验成果。

The key hydraulic problems for the water discharge structure of Guanyinyan Hydropower Station are studied by experiments, including aeration and cavitation prevention test of double discharge middle outlets, stilling basin shape optimization test for the open channel spillway and canceling mid-partition test for river-bank spillway. The result shows that, (a) the aeration effect for cavitation prevention of chute bottom of double discharge middle outlets is good; (b) the stilling basin with step-down and diffuser in the channel spillway can fully dissipate energy, the hydraulic parameters near the bottom are smaller, but the structural stability design of key areas in the floor should be improved;and (c) the canceling of mid-partition for river-bank spillway nearly does not affect the effect of energy dissipation and erosion resistance of downstream river channel, but the operation flexibility of station will be weakened which should be optimized according to operation scheduling test results.
