摘要

首先较为全面地阐述了采用理论分析、风洞试验、现场实测和数值模拟四种方法研究大跨度桥梁涡激振动的主要成果;然后分析了影响涡激振动的主要影响因素,细致总结了主梁、桥塔、缆索和拱肋等主要构件涡激振动特点;介绍了各种抑振措施,以提高涡激振动起振风速和限制涡激振动振幅;最后对大跨度桥梁涡激振动研究的现状进行了总结,并对今后的研究重点和发展方向进行了展望。

Abstract

For the vortex-induced vibration of long-span bridge, the main achievements of theoretical analysis, wind tunnel test, field measurement and numerical simulation are comprehensively reviewed in this study. The primary influential factors of vortex-induced vibration are also analyzed and the vortex-induced vibration characteristics of major components, such as girder, pylon, cable and arch rib, are summarized in detail. Furthermore, the vibration suppression measures which enhance the on-set wind velocity and limit the amplitude of the vibration are presented. In the end, for the vortex-induced vibration of long-span bridge, the conclusions and recommendations for future emphasis and directions are addressed.
