针对山区河流陡峭、流速高以及含沙量高而导致的传统溢流坝消能率不足，下游冲刷剧烈的问题，通过对传统溢流坝进行改进，提出反弧式和二级消力池结合的阶梯式溢流坝，以此提高溢流坝的消能率，降低下游冲刷。对优化后的溢流坝进行模拟测试，其结果显示，反弧阶梯式溢流坝的消能率能够达到79.3%，相对于以前的直角阶梯溢流坝有所提高，并且消力池出口的水流流速可由5.73 m/s降低至3.82 m/s。而在实际测试结果中也显示，使用反弧阶梯式溢流坝后，在单宽流量为0.2 m2/s、0.6 m2/s和1.2 m2/s时，消能率分别

Aiming at the problems of insufficient energy dissipation efficiency and severe downstream erosion of traditional overflow dams caused by the steep slope, high flow velocity and high sediment concentration of mountainous rivers, a stepped overflow dam combining reverse-arc and two-stage stilling basin is proposed by improving the traditional overflow dam, so as to enhance the energy dissipation efficiency and reduce downstream erosion. Simulation tests were carried out on the optimized overflow dam. The results show that the energy dissipation efficiency of the reverse-arc stepped overflow dam can reach 79.3%, which is higher than that of the conventional rectangular stepped overflow dam. The flow velocity at the stilling basin outlet can be reduced from 5.73 m/s to 3.82 m/s. The field test results also show that with the reverse-arc stepped overflow dam, the energy dissipation efficiencies are 78.4%, 69.5% and 62.1% at unit discharges of 0.2 m2/s, 0.6 m2/s and 1.2 m2/s respectively, which are higher than 72.1%, 58.3% and 49.2% of the traditional overflow dam. The above results indicate that the proposed overflow dam can effectively improve energy dissipation efficiency and reduce downstream scouring intensity, thus providing a highly efficient, economical and low scouring new dam type for flood discharge and energy dissipation of mountainous river water control projects.
