| 摘 要： | 在综合考虑静风荷载与结构非线性影响的基础上，采用增量与内外两重迭代相结合的方法对大跨径悬索桥静风稳定性进行了全过程分析．以江阴长江大桥为例，验证了该方法的可行性．最后，探讨了结构布置方式、初始攻角以及主缆的垂度效应等因素对大跨径悬索桥静风稳定性的影响．

| Abstract: | A new method which is used to solve wind-induced lateral-torsional problem for long-span suspension bridges is proposed. Nonlinear influences caused by structure and aerostatic load are included in this method. Numerical results are presented to demonstrate the accuracy and effectiveness of this new method. Finally, the effects of bridge layout, the angle of incidence and cable sag on aerostatic stability of long-span suspension bridge are discussed. |
