在中型拱坝表孔泄流布置中，当下游一侧有危岩体，挑射水流对岸坡或边坡有直接冲击，而调整溢洪道坝轴线又受到地形、地质等条件制约时，可以考虑采用导流贴角这一工程措施。采用数值模拟方法研究了龙潭嘴水电站表孔挑流消能下游的水力特性，对闸墩尾部的贴角方案进行优化研究。对水舌跌落位置、水流流速分布、紊动能耗散率、消能率等水力特性进行了对比分析。结果表明，采取闸墩尾部设置贴角方案较为有利。

In the medium arch crest spillway discharge arrangement,when the downstream side has dangerous rock mass,water jets on the slope or the slope has a direct impact,but also by adjusting the spillway dam axis topography,geology and other conditions restricting,the use of diversion fillet may be an engineering a measure for local conditions. This paper mainly studied by numerical simulation table Longtanzui Hydropower Station hole pick flow downstream of the hydraulic characteristics of energy dissipation on the pier tail fillet program optimization studies. Water drops on the tongue by location, flow velocity distribution;hydraulic characteristics of turbulent energy dissipation rate of energy dissipation rate were analyzed. The results show that the tail is set to take the pier fillet scheme is more favorable energy dissipation.
