Abstract:The model experiment is widely used as a key method to determine the reconstruction scheme of curved spill-way.With regard to the project problems as the torrent shock wave in curved chute and flood discharge energy dissipation in the reconstruction scheme of Tanghe Reservoir,a composite energy dissipation system of multi-stage plunge with bottom flow is recommended based on model-test results.The scheme is composed of the first-stage stilling basin with two high-low slope banks at the inlet and outlet in the curved chute and the second-stage stilling basin which has a baffle sill at the inlet and an anti-scour trench behind the baffle wall.The combination of various dissipators,including multi-stage plunge,two-stage stilling basin,baffle sill and anti-scour trench,could not only make full use of the terrain,but also improve the flow condition,thus properly solving the energy dissipation and scour prevention of the spillway.
