摘　　要：用子空间迭代法对武汉白沙洲大桥的动力特性进行了计算，并根据反应谱理论分析了大桥的抗震能力，采用Ｖａｎｄｅｒｐｕｔ公式和Ｈｅｒｚｏｇ公式分析了大桥的抗风稳定性。并对抗震标准和抗风分析提出了一些看法，其中抗风稳定性在主梁节段模型颤振试验中得到了验证。结果表明，本桥的抗震抗风能力是有保证的。In this paper,the dynamic characteristic of the Wuhan Baishazhou Bridge is analysed by sub space iteration method,for aseismic capacity according to the theory of earthquake response spectrum,and for anti wind stability by Van der put and Herzog Formulas.Some views about aseismic standard and anti wind analysis are put forword.Anti wind stability was proved in the flutter experiment of the main girder model.It is found that the aseismic and anti wind capacity of this bridge is ensured.
