| 摘 要： | 综合考虑了几何非线性和材料非线性对混凝土拱桥稳定性的影响,并结合金沙江大桥的实例分析,对拱箱吊装合拢时的最不利阶段及成桥状态下的稳定性进行了分析,得到在计算拱桥的稳定性时,可不考虑几何非线性的影响,但材料非线性的影响不能忽略的结论。

| Abstract: | It makes a comprehensive study on effect of concrete arch bridge stability of geometrical nonlinearity and material nonlinearity. Combined with the practical analysis of Jinshajiang Bridge, it analyzes stability on the most tmfavoring stage and bridge-forming condition, and concludes that the influence of geometrical nonlinearity and material nonlinearity can be ignored but material nonlinearity must be considered during analysis of arch bridge. |
