| 摘 要： | 通过一个工程实例,分析了钢管混凝土拱桥的稳定分析理论,在施工中考虑线性和非线性稳定性,得到了2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。

| Abstract: | According to an concrete filled steel tubular arch bridge,the linear and nonlinear stability is analysed and the related safe coeffients are got. Rational filling method for concrete filled steel tube and some temporary safety facilities in construction can increase the coefficients of stability. The nonlinear must be considered in the analysis of stability of concrete filled steel tubular arch bridge in construqction. |
