摘　　要：为验证溢洪道陡槽弯道设置导流墙对挑流消能效果的影响,以某水库为例,对弯曲溢洪道进行水工模型试验,对比了溢洪道陡槽弯道设置导流墙前后挑流流态、冲坑淘刷形态和消能率,评价了导流墙对挑流消能效果的优化作用。试验结果表明,溢洪道陡槽弯道设置导流墙使水流流态分布均匀、冲刷坑面积及深度减小且对称分布,消能效果更好。The hydraulic model test of curved spillway is carried out to evaluate the effect of setting guide wall in curved section of spillway chute on ski-jump energy dissipation.Optimization effects of ski-jump energy dissipation with guide wall are evaluated by comparing the flow pattern of jet trajectory,the scour pit pattern after brushing and energy dissipation ratio with conditions of setting guide wall in curved section of spillway chute or not.The results show that setting guide wall in curved section of spillway chute can make flow pattern uniform and scour pit symmetric distribution,reduce the area and depth of scour pit and raise energy dissipation ratio.
