通过对二滩水电站水力学试验资料的研究 ,根据水流运动规律 ,粗略地推导出了溢流拱坝挑流水舌入水宽度的计算公式为 :B=B1+2 L1× (tgα- tgβ) ,此公式可供设计参考。
Based on the study of hydraulic test data of Ertan hydropower station, according to the law of water flow, the calculation formula of water inlet width of overflow arch dam is deduced as follows: B = B1 + 2 L1 × (tgα-tgβ) Formula for design reference.
