Abstract:
Among the low dams of the low dam or low Buddha, the application of the wide -tail pier has changed the water flow structure. The situation is very obvious in the study of the wide -tailed pier of the Yellow River Hydropower Station in the flooding road. This unique water flow form can be called a wide -tailed pier water leap. This article first describes the mechanism of wide -tail pier water leaps, and discusses several key issues in the wide -tailed pier water leaps: through the measurement of the wave element, the inhibitory effect of the wide tail pier on the wavy waves is analyzed; through the measurement of the flow rate and the intensity of the turbulent strength, the intensity distribution and energy efficiency of the wide -tail pier water leaps are analyzed; The pressure sensor and a set of analysis and processing systems reveal the changes in the pulse load of the bottom plate of the wide -tailed pier. Experiments have proved that compared with the high -end pier elimination energy of the high dam, the wide -tail pier is also very effective in the low dam power elimination energy. Use a pier -pool -a binding of the elimination type. It can effectively suppress downstream waves, stabilize the energy body, adjust the flow rate distribution, reduce the low energy of the lower reaches of the lower reaches of the lower reaches, and reduce the low energy of the Buddha’s digital water leap energy, and reduce the scouring of the downstream of the building. Of course, in the specific application of this elimination type, other problems involved in the project must also be considered.
