摘要
近年来钢管混凝土拱肋由于具有良好的力学性能在桥梁结构中得到了广泛应用,文中以一座百米跨度的钢管混凝土拱桥为例,采用生死单元的方法对结构施工过程进行了有限元模拟,分析了施工过程中结构的应力与变形情况。
For recent years, the steel-tube concrete is widely used in the bridge structure because of its good mechanical performance. The paper take a more than 100-meters steel-tube concrete arch bridge as an example and made a simulation of the construction process by the live＆dead element methods. The paper also analyzed the stress and the distortion of the structure in the construction process and provides some reference for the control of the structural construction.
