【摘要】 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。更多还原

【Abstract】 Based on home and abroad studies of bucket flow energy dissipation a new type of comprehensive energy dissipation method,the basin crack bucket flow energy dissipation installation,is put forward in this thesis. Comparing experiments with basin bucket flow energy dissipation were carried out and the hydraulic calculation formulas of the basin crack bucket flow were deduced. By theoretical analysis,the principle of energy dissipation enforcement of the basin crack bucket flow energy dissipation installation was expounded. By analysis of ex.penment results,the experiential scouring formulas of lower reaches were obtained,which supplies a practical hydraulic calculation method.更多还原
