摘要
本文系统地研究了宽尾墩戽式消力池联合消能工的水力特性,并和常规平尾墩型戽式消力池进行比较,试验表明,宽尾墩型戽式消力池极其有效地提高了平尾墩戽式消力池的消能效果。文中提出了宽尾墩型戽式消力池的水力计算方法,并阐明其消能机理,宽尾墩戽式消力池在岩滩工程中的研究和应用,说明宽尾墩戽式消力池是一种解决大单宽流量、低佛汝德数消能难题的有效而经济的新型水工建筑物。
This paper describes the hydraulic characteristics of bucket basin equipped with flaring gate piers (FGP),which have been investigated,systematically in a hydraulic model.An analytic method of the hydraulic characteristics has also been established and the mechanism of energy dissipation can be expounded.The study reveals that the FGP bucket basin can markedly enhance energy dissipation comparing with the conventional bucket basin.It is seen that the FGP bucket basin furnishes a new way to deal with the problems of energy dissipation with deep tailwater and at low Froude numbers due to large specific discharges.
