对于中低水头径流式水电站,通常采用底流消能方式来消减过坝的水流能量,在消能的过程中消力池中水跃的形式、强弱以及辅助消能工的布置形式直接影响整个消力池的消能效率.通过模型试验,结合具体工程实例,探讨了消力池内布设辅助消能工后对水跃消能效率的影响,以及消能工的合理布置对于优化消力池结构的作用,研究辅助消能工的消能规律,为实际工程提供参考.
For medium and low head runoff hydropower stations, the underflow energy dissipation method is usually adopted to reduce the flow energy of the dam. In the process of energy dissipation, the form and intensity of the water jump in the stilling pool and the arrangement of the auxiliary dissipators directly affect the whole Through the model test and the concrete engineering examples, the influence of the auxiliary energy dissipater in the stilling pool on the hydro-thermal energy dissipation efficiency and the rational arrangement of the energy dissipater are discussed to optimize the structure of the stilling pool The role of auxiliary energy dissipater energy law to study for the actual project to provide a reference.
