| 摘 要： | 风是一种重要的自然现象,悬索桥因风的作用而产生的灾害事故屡见不鲜。施工中悬索桥尚未形成最终的结构体系,结构刚度比较小,风作用下的抗风安全性已经成为影响悬索桥安全顺利架设的重要问题。从施工中悬索桥抗风稳定性的变化规律、抗风措施及分析方法三个方面,系统地回顾了近10余年来的研究进展,并指出了研究中存在的问题,同时展望了21世纪超大跨径悬索桥施工过程抗风研究中需要解决的关键问题。

| Abstract: | Wind is an important natural phenomenon,disasters resulting from the wind action are frequently reported for suspension bridges.For suspension bridges under construction,the final structural system is not formed,their structural stiffness is greatly reduced,and the wind stability therefore becomes an important problem influencing the construction safety.The advances in the later 10 years' research on the evolution of wind stability with erection,the wind-resistant measures and the analytical method are comprehensively reviewed,and some deficiencies are also pointed out.Finally,some important problems regarding the wind-resistant research on super long span suspension bridge in the 21~(st) century under construction are prospected. |
