To address the contradiction between supply and demand of water resources in China, mitigate flood and drought disasters, develop sustainable hydropower resources, realize the transformation of the energy industry structure, and realize the Chinese dream of building a beautiful China, the construction of high dams and large reservoirs is imperative. The gates of such conservancy and hydropower structures play an important role in regulating water resources. Only through the flexible operation of gates can the high dams and large reservoirs be adjusted in real time to meet the needs of flood control, power generation, and water resource allocation. The safety of gates largely determines the security of the dams and the life and property of people residing downstream. Therefore, the safety design of gates is of utmost importance. This paper presents a comprehensive analysis of the status of development of water conservancy and hydropower engineering gates; material selection, connection methods, classification, selection, design of gates; as well as the design codes for gates in international engineering. This paper also elucidates the emerging trends related to materials, structures, connection methods, and design methods of gates.
