摘　　要：以罗泊湾大桥为背景,在MIDAS/Civil软件中建立了罗泊湾大桥成桥状态的整桥模型,对其施加二期荷载,得到了结构的整体挠度;接着对其进行自振特性分析,得到结构的前10阶自振频率及振型,可为类似桥梁的稳定性分析提供参考。On the background of one of the Roberto Bay Bridge,the whole model of Roberto Bay Bridge in the completion state was established based on MIDAS Civil,and the overall deflection was obtained through adding a second phase of load. Besides,the first 10 natural frequencys and vibration mode were obtained through natural vibration analysis.And the paper could provide a reference for the stability analysis of the similar bridge.
