本文提出的一种新型的综合性消能工，为池式掺气窄缝墩戽流消能，与常规的戽式消力池进行了比较。试验表明：池式掺气窄缝墩戽流消能极明显地提高了消能效果，文中给出了戽内断面水深ｈ１、窄缝墩绕流阻力系数Ｃｄ以及下游界限水深ｈｔ的计算公式，同时对下游河床的冲刷进行了分析，给出了冲坑长、冲坑深的经验公式。 A new type of integrated energy dissipater proposed in this paper is used to simulate the energy dissipation of pool-type aerated narrow-gap pier, compared with the conventional 消-type stilling pool. The experimental results show that the energy dissipating effect of the pool aerator can obviously improve the energy dissipation effect. The calculation formula of the water depth h1, the drag coefficient of flow around the narrow pier Cd and the downstream water depth ht is given in this paper. At the same time, the erosion of the downstream riverbed is analyzed, and the empirical formula of pit length and pit depth is given.
