Abstract: Single-Plane cable-stayed bridges have ad vantage of a better view of the surrounding area,in thesametime they have also some problems,such as the wind-resistance stabllity,as the cables have notorsion stiffness. This paper studies the fluttering characteristics of single-plane cable-stayed bridgestheed On the analysis of wind-resistance stability in the bidding design for a bridge.

Key words: single-plane cable-stayed bridge, fluttering

摘要： 单索面斜拉桥具有桥面视野开阔的优点，但是由于拉索不能提供抗扭刚度，单索面斜拉桥的抗风稳定性问题就比较突出。本文通过作者对某大桥单索面斜拉桥投标方案的抗风稳定性分析，对单索面斜拉桥的颤振特性进行了研究。
