大跨径劲性骨架箱肋拱桥施工仿真分析

Analysis of long span rigid frame arch bridge construction simulation

以大跨度劲性骨架拱桥为研究对象,采用有限元程序建立全桥空间计算模型,根据拟定的施工顺序对施工阶段各控制截面的应力、变形和稳定性进行了分析,研究了其施工阶段划分的合理性,为施工控制提供依据,为同类桥梁的设计、施工提供借鉴。

Taking a long-span arch bridge with rigid frame as the research object, sets up the whole bridge space calculation model by the finite elementprogram, according to the order of construction, analysis construction stage of the control section of the stress, deformation and stability, researched the rationality of construction stage division, to provide the basis for the construction control, design, provide a reference for the simi lar bridge construction.
