温头口电站整体水工模型试验研究

Study on the Integer Hydraulic Model Tests of Wentoukou Hydropower Station

阐述了温头口电站整体水工模型试验的主要内容和试验方法。通过水工模型试验 ,计算了溢洪道的泄流能力 ,校核了挡墙和泄槽边墙的设计高度 ,分析了坝体产生气蚀的可能性。提出了优化溢洪道进口的布置方案 ,并根据下游消能冲刷情况 ,建议对下游岸坡采取适当保护措施。研究成果对工程设计和其他模型试验均具有一定的借鉴意义。

This paper examines the main contents and methods of the integer hydraulic model tests of Wentoukou Hydropower Station. Through the tests, the discharge capacity of the spillway is computed; the design wall heights of the retaining structure and the overflow groove are verified; and the probability of cavitation is also analyzed. An optimized layout of the spillway inlet and suggestions for protecting the riversides downstream according to the energy dissipation scouring are proposed. The results may present references for project design and other model tests as well.
