| 摘 要： | 以实桥为例,建立了空间分析的有限元模型,对大跨径钢管混凝土拱劲性骨架拱桥施工阶段的稳定性进行了线性和非线性分析,得出在施工过程中非线性对稳定性的影响十分显著,计算施工时的稳定系数必须考虑非线性。

| Abstract: | The paper is based on the study of the real bridge,and a model of limited element has been built.The stability of every construction procedure of the long-span CFST stiff-skeleton arch bridge has been analyzed,the nonlinearity and linearity is also considered.At last,we can get that the influence of the nonlinearity to the stability in the construction procedure is very large,and the nonlinearity must be considered in the calculation of the stability coefficient of the construction procedure. |
