| Abstract: |
| In recent years, with the rapid development of water conservancy and hydropower, many hydropower engineering projects having high dams and large reservoirs have been built or are currently under construction. In the meantime, the design and installation requirements of the hydraulic gate structure are constantly improving. In order to solve the frequent vibration problems of the hydraulic gates in engineering practice, a lot of research and analysis have been carried out by relevant scholars. The hydraulic gate vibration seriously affects the normal operation of the dam, and even threatens the development of the national economy and the safety of people’s lives and property. Therefore, it is necessary to find out the causes of the hydraulic gate vibration and take corresponding measures to avoid the adverse vibration. Based on the current theoretical methods and findings, the research progress of the hydraulic gate vibration is introduced in detail in this paper from the aspects of vibration phenomena, gate vibration grade standards, research methods, analysis of gate vibration inducement and corresponding gate structure optimization measures, dynamic stability of radial gate and active vibration control methods. And problems that need to be solved urgently and six research directions in the future are put forward, which can provide technical support and reference for further research on the hydraulic gate vibration. |
