Abstract: On basis of analyses on development and application of large and wide gates in China, this paper points out that these gates have improved the construction level of hydraulic engineering the variety of outlets and the patterns of retaining structures. Besides, the design and manufacturing level of metal structures have also been developed. Meantime, because of structural size, much bigger than before, and different ways of gate operation, flow-induced vibration problems of gate structures are also conspicuous, and become one of important controlling factors affecting engineering safety operation. Operation characteristics and flow-induced vibration of these new types of gates and sluices are expounded, and basic vibrating sources for different types of gates are also given. Modeling techniques of the gate flow-induced vibration and the way of anti-vibration optimization are introduced, and different types of gates and vibration controlling and optimization methods are put forward.
