侧槽溢洪道的水流条件比较复杂,尤其是过堰水流进入侧槽后,形成横向漩涡,同时侧槽内沿流程流量不断增加,漩滚强度也不断变化,水流紊动和撞击都很强烈,水面极不平稳。科克塔斯水库坝址处山头高、岸坡陡峭,岸边式溢洪道根据具体地形特征选用了侧槽溢洪道。文章结合科克塔斯水库的具体情况,对侧槽溢洪道侧槽段、泄槽段、出口消能段进行了研究,重点对溢洪道侧槽水力学计算进行了研究。
Sideflow spillway flow conditions are more complex, especially over the weir flow into the side of the groove, the formation of horizontal vortex, while the flow along the side tank along the growing flow of swirling intensity is also changing, the turbulence and impact of the water are very strong, the water surface Very unstable. Cottes Reservoir dam site at the top of high, steep slope, shore-based spillway selected according to the specific topography of the side channel spillway. Based on the specific conditions of the Cotters Reservoir, the article studies the side channel spillway side channel section, the leakage channel section and the outlet energy dissipation section of the spillway, and emphatically researches the hydraulics calculation of the side channel of the spillway.
