| 摘 要： | 针对某铁路大跨度悬索拱桥，考虑结构的非线性和构件的极限承载能力，计入施工过程的变形和应力的叠加效应，用包含梁和索单元的空间组合结构模型，进行了大桥的结构行为分析。 着重研究了结构在施工及运营过程中的非线性变形、内力和稳定性，并探讨了荷载在悬索拱桥的拱间的分配问题。

| Abstract: | A 3 dimensional compound structural calculation model constructed by beams and rope elements is used to analyze the structural behavior of a certain long span suspended arch bridge. In the analysis, the structural nonlinearity and ultimate bearing capacity of members are considered, and the deformations during construction and the superposition effect of stresses are also taken into account. The emphasis of the study is focused on the nonlinear deformations, internal forces and stability of the bridge during construction and operation. Meanwhile, The distributions of dead and live loads between the cable and arch of the bridge are discussed. |
