摘要
喜河水电站左三表孔溢流堰上游面为垂直面，堰面头部为三圆弧复式曲线，消力池末端设差动式尾坎，体型总体设计是合理可行的。在此设计方案试验观测与分析的基础上，本着改善表孔泄洪流态、保证下游冲刷安全和结构合理、便于施工的原则，着重就消力池尾坎体型和护坦型式做了多种方案的修改比较，最终提出较优的推荐方案。
The upstream face of overflow weir of left third surface orifice in Xihe river hydropower station is vertical plane; weir head features a three-arc multiple curve;a differential tail-end is set at the stilling basin; the overall design of the form is reasonable and feasible. Based on the observation and analysis on this design scheme,in order to improve the surface flow pattern to ensure downstream scouring safe, structure rea- sonable,and convenient construction,we made various scheme comparisons on stilling tail shapes and apron types, and put forward the better recommended plan.
