消力戽是一种较新型的消能建筑物。初步实践表明,消能效果良好,下游冲刷较轻,特别是它的体型较小,工程量省,因此近年来采用这种消能形式的工程日渐增多。但正因为它是新发展起来的消能工,理论和实践均不完善,具体计算方法更感缺乏,只能凭借水工模型试验来加以鉴定,因而给工程设计带来不少困难。本文结合实际工程试验对连续式消力戽的水力特性作了一些试验研究,并在此基础上提岀了计算消力戽水跃的理论公式——戽跃基本方程式。经与同类工程的试验结果比较,计算与实测尚较符合,可供工程设计参考试用。为了便于计算,文中还列出了一些典型算例。 Consumption 戽 is a relatively new energy-dissipating building. Preliminary practice shows that the energy dissipation effect is good and the downstream scouring is light. In particular, because of its small size and reduced construction volume, the project adopting such energy dissipation forms has been increasing in recent years. However, just because it is a newly developed energy dissipater, both theory and practice are imperfect, and the specific calculation method is more scarce. It can only be identified through hydraulic model tests, which brings many difficulties to engineering design. In this paper, some experimental researches on the hydraulic characteristics of the continuous hydrants are carried out based on the actual engineering tests. On the basis of this, the theoretical formula for calculating hydraulics of the hydrants is also presented. Compared with the test results of similar projects, the calculation and measurement are still more in line with, for engineering design reference trial. In order to facilitate the calculation, the article also lists some typical examples.
