摘　　要：针对一座钢 -混凝土组合结构的人行桥 ,用板壳有限元法计算了其施工过程中的稳定性 ,讨论了临时支承沉陷对其稳定性的影响 ,计算比较了临时支承沉陷量与其弹性稳定系数之间的关系。According to the analysis by shell element of finite element method, the stability during construction of a composite bridge of steel and concrete was calculated, and the effect that the settlement of temporary support acts on the stability of composite beam of steel and concrete was discussed. The relation between the settlement of the temporary support and the elastic stability factor was also discussed.

关 键 词：结合梁桥 桥梁施工 稳定性 有限元法 力学分析
