摘要
设计和建造跨海连岛大桥将面临着许多技术方面的挑战,其中超大跨径悬索桥的抗风稳定问题是一个十分突出和必需关注的问题。本文系统地回顾了国内外在大跨径悬索桥抗风措施方面的研究进展,包括结构措施、空气动力学措施和机械措施等三个方面,并评述了各种措施的优缺点及其适用性。
A Large number of technological challenges are presented in the design and construction of crossing sea and linking islands bridges, in which the aerodynamic stability of extra long span suspension bridges is a dominant concern, The advance in the research on wind-resistant measures of long span suspension bridges at home and abroad is comprehensively reviewed, including the structural, aerodynamic and mechanical measures, and the merits and demerits of each measure and their applicability are also evaluated.
