摘要
在分析我国大跨度闸门研制开发进展、应用现状和趋势的基础上,指出大跨度闸门的研发和应用既丰富和提高了我国水利工程建设水平和挡泄水结构的多样性,又表明我国的金属结构设计和制造水平得到显著提高,但由于结构尺寸的增大和运行方式的不同,闸门结构的流激振动问题也日益突出,成为影响工程安全运行必须考虑的首要问题之一.为此,文中阐述了各类新型闸门的运行特征和流激振动特点,给出闸门结构的动态优化和振动控制措施.
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.
