60～70年代,不少国家已开始将通气减蚀这一新技术应用于工程实践。我国自1976年首次将通气减蚀设施应用于冯家山水库溢洪洞以来,至今已建、在建的通气减蚀设施约有20个,占世界总数的1/4左右。实践证明,通气减蚀技术的应用,为解决泄水建筑物防空蚀问题开辟了一条新途径,收到了较好的效果。本文在收集研究国内外80多个通气设施的科研、设计、运行资料的基础上,着重对通气设施的类型、设计的基本要求、体型尺寸选择、水力指标的估算及模型试验等方面进行介绍,供有关人员参考。
From 1960s to 1970s, many countries started to apply the new technology of aeration and erosion reduction to engineering practice. Since the first application of aeration and erosion mitigation facilities to the Fengjiashan Reservoir spillway in 1976, China has built and built about 20 facilities for aeration and erosion reduction, accounting for about 1/4 of the world total. Practice has proved that the application of aeration corrosion technology, to solve the problem of anti-cavitation venting buildings opened up a new way, received good results. Based on the collection of the research, design and operation data of more than 80 ventilation facilities at home and abroad, this paper mainly introduces the types of ventilation facilities, the basic design requirements, body size selection, hydraulic index estimation and model tests, For the relevant personnel reference.
