研究結果表明:設置低坎分流墩后,消除了擺動水躍水舌擺動的根源,提高了水躍的消能效果,改善了下游水流流態。下游水體的主流在中部,既有效的降低了坎后水流底流速,減輕水流對河床的沖刷,又避免了主流位於表面導致波浪過大的結果,下游的水面波浪明顯得到削減。依據經驗公式,可根據工程水流條件設計出低坎分流墩的體型參數,進而估算出下游沿程的水面波浪,為下游岸邊的砌護提供依據。The researches including discharge capacity, pressare properties, cavitation characteristics at some key positions, hoisting load of the gate, configuration of energy dissipator at the exit dentated - sill, and downstream scouring were performed by hydraulic model tests
