摘要
低水头闸坝工程的一个普遍水力学问题是低佛氏数水流的消能防冲 ,其特点是消能率低 ,为达到较好的消能效果 ,常在消力池中加设一些辅助消能工 .结合沂沭河上某节制闸的消能试验 。
In low water head hydraulic constructions, a common hydraulic problem is energy dissipation about small Froude number water flow, which energy dissipation is less efficiency. Some supplementary structures are generally applied in stilling pool to get better result of energy dissipation. Based on the energy dissipation experiment of a block on Yishu River, two kinds of supplementary dissipater with more efficiency in small Froude number flow are given. [WX(5KG0,41]
