Embodiment Construction
[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0028] A combined energy dissipation method for a hydropower station bank slope and a natural stilling basin, which is implemented as follows figure 1 and figure 2 As shown, a trapezoidal bank slope 3 with a slope of less than 70° is set below the outlet of the spillway of the hydropower station. The bank slope 3 is formed by a flat lining of a natural bank slope. After the water flows down the bank slope 3 to reduce the single-width flow rate, a natural stilling pool 6 is washed out at the edge of the downstream riverbed 2, and the water flowing out of the spillway outlet flows through the bank slope 3 and the natural stilling pool 6 after combined energy dissipation. Discharge along the river bed 2. During implementation, multiple rows of stilling piers 4 are horizontally arranged on the bank slope. The stilling piers 4 are pier-...
