摘要:

斜拉桥作为一种现代桥梁结构,在大跨度、结构美观、施工便利等方面具有明显优势,因此越来越受到工程师和设计者的青睐,并成为城市建设和交通基础设施的重要组成部分。但斜拉索振动对桥梁结构的安全运营和维护成本构成了严重威胁。因此,发展有效的斜拉索振动控制技术成为当务之急。综述了近年来关于斜拉索减振技术的研究进展,包括斜拉索振动主要类型、振动控制方法及斜拉索减振效果提升方法与技术 3 个方面,总结了各种方法与技术在斜拉索减振方面的优势。最后,阐述了一些施工期间斜拉索的减振措施。

As a modern bridge structure, cable⁃stayed bridges have obvious advantages in terms of largespans, structural aesthetics, and ease of construction, so they are increasingly favoured by engineers anddesigners, and have become an important part of urban construction and transportation infrastructure.However, the vibration problem of stay cables poses a serious threat to the safe operation and maintenancecost of bridge structures. Therefore, the development of effective vibration control technology for staycables has become an urgent task. This paper reviews the research progress on the vibration controltechnology of stay cables in recent years, including the main types of vibration of stay cables,vibrationcontrol methods, and new methods and technologies to enhance the vibration control effect of stay cables,and this paper also summarizes the advantages of various methods and technologies in vibration control ofstay cables. Finally, some measures for vibration control of the stay cables during construction aredescribed.
