Rectification energy dissipation method for inverse step stilling basin and stilling basin
The invention discloses a rectification energy dissipation method for an inverse step stilling basin and the stilling basin. A conventional end sill shape is replaced with a continuous inverse step end sill at the tail end, so that water flow collides with the end sill in a layering manner, the phenomenon of surge caused by straight wall type or steep slope type end sill collision and more concentrated water flow impact force in the basin are avoided, the flow regime of collision, mixing and turbulence of the water flow which is not discharged from the basin can be enhanced, and by collision energy dissipation and increasing of conjugate water depth of water jump, the length of the basin can be effectively decreased, energy dissipation rate can be increased, and energy dissipation and speed regulation functions can be realized. The rectification energy dissipation method and the stilling basin are applied to the conditions of high and medium water heads, high Fr coefficient, connection of the stilling basin to the downstream, uniform inflow and outflow and coaxiality between the axis of a river channel after an outlet and the water flow discharged from the basin.
