摘　　要：为改善巴山水电站溢洪道进水渠流态、提高泄流能力,通过一系列试验优化了溢洪道引水渠左导墙头部曲线型式.结合工程实际和以往经验,比较了9种进水口曲线型式的试验结果,确定了长短轴黄金分割比的椭圆弧面的方案.进一步的试验证明了该方案无论在流态上还是在泄流能力方面都达到了令人满意的效果.To improve the flow pattern and discharge capacity of the spillway of Bashan Hydropower Station, the left guide wall＇s form of the spillway＇s entrance channel is optimized by series of model tests. Taking practical situation of this project and much engineering experience into account, the scheme with axle golden section elliptical arc surface is proposed through comparing nine optimization schemes with model test. Further tests show that this scheme is satisfactory in both flow pattern and discharge capacity.
