| 摘 要： | 通过对大跨度中承式钢管混凝土桁式拱桥———南宁永和大桥施工稳定性研究,在分别考虑线弹性和几何非线性及材料非线性的情况下,分析了吊杆横梁及桥面纵梁安装施工的不同阶段拱圈稳定性变化。研究中将非线性稳定分析结果与线弹性稳定分析结果进行比较,并结合其他研究人员的研究成果进行分析,发现非线性对钢管混凝土拱桥稳定性的影响与拱桥的跨度、加载的方式等因素有关。

| Abstract: | In this paper,the stability of Yonghe Bridge,which is a long-span steel-tube concrete arch bridge,is analyzed by linear elastic theory and geometrical nonlinear theory and material nonlinearity theory.When the nonlinear stability analysis and linear elastic analysis are compared,the conclusion indicates that the influence of the nonlinearity on the stability of the steel-tube concrete arch bridge correlates with the factors,such as the span of the bridge,the load way,and so on. |
