摘　　要：为验证四川省官帽舟水电站溢洪道和泄洪洞布置方案的合理性,通过水工模型试验,研究了该水电站的进水条件、泄洪能力、挑流消能效果及冲坑范围等。同时,根据试验结果优化了墩尾及闸室、挑流鼻坎结构型式及下游右岸边坡开挖支护方案。结果表明:官帽舟水电站溢洪道和泄洪洞进出口流态稳定,泄流能力满足设计要求;优化后的方案更加安全合理,有效减少了开挖工程量并降低了项目成本。In order to verify the layout scheme rationality of spillway and flood discharging tunnel of Guanmaozhou hydropower station in Sichuan Province,the inlet hydraulic conditions,flood discharge capacity,flip energy dissipa⁃tion effect and scoured pit range of the hydropower station were studied through hydraulic model test.Also,accord⁃ing to the test results,the structural types of pier tail,gate chamber and flip bucket and the excavation and support scheme of the downstream right bank slope were optimized.The results showed that the flow pattern at the inlet and outlet of the spillway and in flood discharging tunnel of Guanmaozhou Hydropower Station were stable,and the dis⁃charge capacity met the design requirements.The optimized scheme is more safe and reasonable,which can effec⁃tively reduce the excavation quantities and construction cost.
