Hydraulic design method for guiding energy dissipation of double-curved spillway
The invention provides a hydraulic design method for guiding energy dissipation of a double-curved spillway, belongs to the technical field of water conservancy and hydropower engineering, and relates to energy dissipation, scour prevention and water flow guiding design of the double-curved spillway under specific conditions. According to the method, the problems of water flow guiding, energy dissipation and scour prevention of the double-bend spillway are finally solved, and the problem that a conventional single flow guiding and energy dissipation mode is poor in improvement effect on water flow state deterioration caused by centrifugal force superposition influence on short-distance double-bend water flow is solved.
本发明提供一种双弯曲溢洪道导向消能的水力设计方法，属于水利水电工程技术领域，本发明是对特定条件下的双弯曲溢洪道进行的消能防冲及水流导向设计，通过圆柱消力墩+弧形导流墩+消力池+斜底槛+台阶几种导流消能工的联合运用，最终解决双弯曲溢洪道的水流导向及消能防冲问题，该方法克服了常规单一的导流消能方式对短距离双弯道水流因离心力叠加影响而造成水流流态恶化改善效果较差的问题。
