| 摘 要： | 考虑施工过程中结构体系不断变化、荷载逐步增加以及拱桥结构大位移等因素，建立了大跨度拱桥结构的非线性稳定计算模型，编制了相应的程序。文中对某拱桥施工全过程的稳定性和几何非线性模拟计算，得出了各个施工阶段稳定安全和非线性影响系数；计算结果为该大桥设计和施工提供了理论依据。

| Abstract: | In
view of the effects of structural system change as well as the ever-increasing loads
during erection phases, an approach to the stability analysis of the arch bridge is
presented. A program is developed and it can predict the nonlinear buckling of the arch
bridge. The elastic lateral stability and the geometric nonlinear influential factors of a
long-span arch bridge during the construction phases are analyzed. Such analyses have
provided the theoretical basis for the construction of the long-span arch bridge. |
