摘要
综合式消力池是底流消能常见的消能方式之一。以模型试验为基础,通过测量水面线、流速以及下游冲刷坑深度等水力学参数表明,齿坎消力池配合增加消力池长度能有效解决一般综合式消力池尾坎存在的水流二次跌落幅度较大、出池水流流速较大、消能率较低以及下游冲刷严重等问题,可为实际工程的消力池设计提供重要的参考依据。
Integrated stilling basin is one of the common energy dissipation methods of bottom flow.Based on the model test,the hydraulic parameters such as water surface line,flow velocity and downstream scour pit depth are measured.The results show that the tooth bucket stilling basin with increasing the length of stilling basin can effectively solve the problems of large secondary drop amplitude,large flow velocity,low energy dissipation rate and serious downstream scour in the tail bucket of general comprehensive stilling basin.At the same time,it provides important reference for the design of stilling basin in practical engineering.
