摘　　要：以安邦河斜拉桥为背景,借助有限元分析软件Midas/Civil,采用子空间迭代法对其进行了计算,得出了该桥的自振特性,计算结果可为该桥后期运营过程中的健康检测与维修提供参考,同时,为进一步认识矮塔斜拉桥的动力性能起参考作用。This paper has treated extradosed cable-stayed bridge of Anbang River as engineering background. By adopting Midas / Civil finite element procedure,and the natural vibration characteristics of the bridge using sub spatial repetitive process is calucated. The result can provide the reference for the health detection and maintenance of the bridge in the process of operation. And it also plays a reference role to further understand the dynamic property of extradosed cable-stayed bridge.
