| 摘 要： | 应用经实桥测试验证的有限元模型,以管内混凝土填充长度系数为参数,对钢管-钢管混凝土复合拱的结构内力、截面应力、拱肋挠度、极限承载力和弹性一类稳定系数进行了分析.分析结果表明:复合拱的主要优势在于稳定性方面,管内混凝土填充至L/4处较合适,但应注意变刚度截面应力的控制.

| Abstract: | Based on the FEM model validated by the field testing,with the parameter of the length for the concrete in tube,the behaviors of the hybrid arch bridge of steel tube and concrete filled steel tube are analyzed by the finite element method.The results show that stress in the cross section of rigidity varied should be taken into account in design.The concrete in tube filled to L/4 is preferable.The advantage of this type bridge is its stability. |
