| 摘 要： | 索道桥是以钢丝绳为主要受力构件的一种柔性悬索体系桥梁。利用有限元软件M IDAS建立某索道桥的空间计算模型,静力计算结果与试验实测值吻合良好。在计入主缆几何刚度的基础上,开展桥梁空间横向稳定性分析,提出多种提高其横向稳定性的方案;通过不同方案下桥梁横向稳定性对比,从中推出最优方案。分析方法与结果可为同类索道桥的设计与施工提供参考。

| Abstract: | Cable bridge is a type of suspension bridge which depends on the wire rope to suffer the external force.The spatial computation model of a cable bridge was established by the finite element program MIDAS.The static results were in good agreement with that of the test.Reckoning in the geometric stiffness of the rope,the spatial lateral stability of the bridge was analyzed and diverse measures were put forward to improve its lateral stability.After comparing with these methods,the best measure was proposed.Th... |
