摘　　要：为了提高公伯峡水电站左岸溢洪道泄槽抗空蚀设计的可靠性、安全余度和减少施工难度,在分析国内外高速水流泄洪建筑物运行实例的基础上,结合公伯峡工程实际,通过水力学模型实验验证,优化设计采用了增加掺气设施,保证高速水流底部充分掺气,从而防止了泄洪建筑物的空蚀破坏。这一措施不仅简单、易行,还可节约工程投资、增大工程安全度和可靠性。In order to enhance the credibility and safety degree of anti cavitation design and to reduce the difficulty of construction, on the basis of analyzing on the examples of high speed flow flood releasing structures at home and abroad, in combination with the actual conditions of Gongboxia hydropower project, we used the hydraulics model experiment and optimal design and adopted the aeration facilities to guarantee the full aeration in the bottom of high speed water flow so that it prevents from cavitation. Such measure is not only simple, easy to use but also can save the investment of project and increase the safety and reliability of the project.
