| 摘 要： | 以独塔单索面混凝土斜拉桥为研究对象，通过建立有限元模型，对其进行动力特性分析，并给出该桥的前10阶频率和振型。在此基础上,研究了质量变化、主梁竖向刚度、主梁横向刚度、塔柱刚度、斜拉索参数单一变化对结构动力特性的影响，并对其影响规律进行了分析，研究结果为同类桥的动力研究提供参考。

| Abstract: | Taking single tower and single cable plane cable-stayed bridge as the research object,through the establishment of finite element model of the bridge,we analyzed the dynamic characteristics.The first 10 order frequencies and modes are given.Based on it,the influence on the structural dynamic characteristics is researched with the changes of the mass,the vertical and transverse stiffness of main girder,stiffness of tower,cable stiffness.The influence laws are analyzed.The results can provide the reference for the similar bridge dynamic research. |
