Abstract

Abstract: The linear and nonlinear buckling analysis on stability are introduced.Then according to an concrete filled steel tubular arch bridge,some aspects in construction about stability were discussed.Rational filling method for concrete filled steel tube and some temporary safety facilities in construction can increase the coefficients of stability.The nonlinear influence must be considered in the analysis of stability of concrete filled steel tubular arch bridge in construction.

Key words: concrete filled steel tubular arch bridge, construction, analysis of stability, nonlinear

摘要： 阐述了钢管混凝土拱桥的稳定分析理论,通过一个工程实例分析了其在施工过程中的线性和非线性稳定性,得到了两种情况下各个施工阶段的稳定安全系数。对钢管管内混凝土采用合理的灌注顺序,以及在施工中设置辅助设施均可以提高结构整体稳定性,保证施工安全。在施工稳定性分析中应考虑非线性的影响。
