溢流坝的弧形工作闸门流激震动状态具有特殊性,同时也具备一般水利枢纽流激震动的普遍特性,而且由于溢流坝建设工程具有灌溉、发电、供水等综合性效益,质量控制时期综合效益得以发挥是促进水利水电工程健康发展的关键因素,文章简单的介绍了溢流坝的弧形工作闸门运行特点,在此基础上,进行流激震动实验,观测溢流坝的弧形工作闸门进口水流流态,并且分析不同开度条件下震动速度、动位移、动应力等的变化情况,总结出溢流坝的弧形工作闸门流激震动的一般规律,指导水利枢纽的正常运行。
Due to the special nature of the flow shock and vibration of the arc-shaped work gate of overflow dam, it also possesses the general characteristics of shock-induced vibration of general hydraulic projects. Moreover, due to the comprehensive benefits of irrigation, power generation and water supply, Comprehensive benefits can be exerted to promote the healthy development of water conservancy and hydropower projects, a key factor in the article simply introduced the operation characteristics of the spillway arc work gate, on this basis, the shock wave experiment to observe the spillway arc work The flow pattern of inlet flow of gate is analyzed, and the change of vibration velocity, dynamic displacement and dynamic stress under different opening degrees are analyzed. The general rules of flow shock of curved work gate of overflow dam are summarized and the normal operation of water conservancy hub is instructed.
