| 摘 要： | 该文运用空间有限元分析对独塔双索面斜拉桥进行抗风性能计算和评估检算,对全桥结构进行动力分析,结果表明,虽然拉索不能提供抗扭刚度,但由于主梁刚度较大,故大桥表现出良好的抗风性能。

| Abstract: | Using the method of spatial finite-element analysis,the article calculates,evaluates and checks the wind-resistant performance of the single-pylon double-plane cable-stayed bridge,and carries out the dynamic analysis of the whole bridge.The result shows that the cable can not provide torsion stiffness,but the whole bridge shows good wind-resistant performance because of the greater stiffness of the main beam. |
