底或面跌流式水垫塘消能机理探讨

Inquiry into Energy Dissipation Mechanism to Plunge Pool of Bottom(or Surface) Drop Flow Type

应用流体力学动量积分方程，详细地分析了底、面跌流式水垫塘流动特征和消能机理，并导出有关水力计算公式。然后，通过一个工程算例，说明整个水力计算过程。计算结果表明，公式是合理的，可为进一步的实验研究和水垫塘泄洪消能布置提供科学依据。

By using fluid mechanics’ momentum integral equations, energy dissipation mechanism are flow characteristic in the plunge pool of the bottom(or surface) drop flow type are analysed in detail and some related formulas and derived. And then, the whole hydraulic calculation process is represented through an engineering illustration. The calculated results show that the provided formulas are rational and can serve as scientific references for further test study and layout design of energy dissipation in plunge pool.
