万家口子水电站大坝金属结构的布置设计

Layout Design of Metal Structure of Wanjiakouzi Hydropower Station Dam

文章介绍了万家口子水电站大坝的金属结构布置与设计特点,借助模型试验研究成果验证指导高水头闸门设计及启闭机容量确定。中孔设置工作闸门(弧门)充压止水和突扩式门槽,较好地满足高水头闸门、运行要求,解决闸门振动、门槽减蚀问题。

This paper introduces the layout and design characteristics of the metal structure of the Wanjiakouzi Hydropower Station dam.With the help of the model test results,the design of the high head gate and the determination of the capacity of the hoist are guided.The mid-level outlet is equipped with operating gate(radial gate) for pressurized waterstop and abruptly expansion groove,which can better meet the operation requirements of high head gate and solve the problems of gate vibration and groove erosion reduction.
