摘  要:竖井旋流内消能技术是一种新的生态流量泄放设施,但其设计标准和工程经验较少。介绍了用于生态流量泄放的竖井旋流内消能技术设计思路、方案及水力计算经验公式,并通过模型试验对其体型进行了优化,解决了泄流能力的协调与匹配问题,通气孔的设计、下游水深的影响等问题,以及掺气、脉动、振动、空化空蚀、雾化、下游河床及岸坡的冲刷等问题。Internal energy dissipation of shaft spillway with whirling current is a new facility of ecological flow discharge, but there is few design standard and practical project to reference. The design ideas, scheme and hydraulic calculation empirical formulas of internal energy dissipation technology in shaft spillway for ecological flow discharge are introduced. The shape of shaft spillway is optimized by model tests. These results solve the problems of the coordination and matching of discharge capacity, the design of ventilation hole, the influence of downstream water level, as well as the aeration, pulsation, vibration, cavitation, atomizing and the erosion of downstream river bed and banks.
