Abstract:With the extensive construction and use of large-scale water conservancy projects, gate, as an important part of hydraulic facilities, plays an important role in the regulation of water resources. However, due to the influence of long-term use and environmental factors, the structure of the gate is prone to damage and failure, which brings certain challenges to the operation and maintenance of the project. Therefore, the maintenance technology research based on time-varying reliability of gate structure is of great significance. In this paper, the research status of flat steel gate at home and abroad is analyzed, and the structural types and characteristics of gate are introduced. Then, the problems existing in the maintenance technology status quo are discussed, such as the limitation of maintenance methods, the problem of technical inheritance and high maintenance cost. Then, the method and tool of reliability analysis are introduced, and the failure mode and influence of gate structure are analyzed. Based on the reliability evaluation, the method of formulating the maintenance strategy of gate is put forward. Finally, the application prospect of the new maintenance technology is introduced, and the improvement suggestions to the existing maintenance technology are put forward. This study has certain guiding significance for improving the maintenance efficiency and reducing the maintenance cost of the gate.

Key words：Gate maintenance, time-varying reliability, failure mode
