| 摘 要： | 大跨度拱桥在施工过程中体系不断变化﹑荷载逐步增加以及拱桥结构大位移等因素,必须考虑拱的变形影响和材料弹塑性影响。该文对大跨度钢管混凝土拱桥进行稳定性分析时,同时计入几何非线性和材料非线性的理论,考虑双重非线性影响。

| Abstract: | It must be to consider the deformation influence of the arch and the influence of the material because of the factors that the system is continuously changed, the load is stepped up and the structure of arch bridge is greatly displaced in the course of constructing the large-span arch bridge. The article analyzes the stability of the large-span steel pipe concrete arch bridge, at the same time, introduces the theory of the geometric nonlinearity and the material nonlinearity, and considers the double-nonlin... |
