白龙江宝珠寺水电站右底孔弧形工作闸门的设计

通过对宝珠寺水电站高水头弧形工作闸门止水试验、水工模型试验和分析比较，确定设计参数，最终采用突扩跌坎式门槽。弧形工作闸门的止水型式，采用了当时中国尚无运行使用先例的框型充水膨胀式止水。该弧门1996年8月正式投入运行，运行10多8来，一切正常。在1998年汛期经历了白龙江历史上400年一遇最大洪水的考验，进一步证明了其设计及参数的选择是合理的，它为今后中国高水头闸门止水型式的研究及发展提供了宝贵的经验。

Design of radial gate for right bottom outlet of Baozhusi hydropower station

Through water sealing test and hydraulic modeling of high head radial gates for Baozhusi hydropower station, and determination of design parameters, sudden enlargement and drop - sill slot was finally applied. The type of water sealing for the radial gate was unprecedented in China at that time. The radial gate was commissioned in August, 1996, experienced the 400 - year flood （maximum event in Bailongjiang＇s history） in 1998, and has operated normally for over 10 years, which proves the design and parameter selection are rational and provides rare experience for study and development of water seal type of high head gate in the future.
