In this paper, the mutual force problem between concrete and steel pipe arch ribs during the construction stage of pumping concrete of concrete-filled steel tubular arch bridge is studied. The whole and local force situation of concrete-filled steel tubular arch bridge during pumping construction is studied by fluid-solid coupling method to provide reference for similar arch bridge construction.%本文主要针对目前钢管混凝土拱桥泵送混凝土施工阶段混凝土与钢管拱肋之间的相互受力问题进行研究,利用流固耦合的方法研究钢管混凝土拱桥在泵送施工阶段的整体及局部受力情况,为类似拱桥施工提供参考.
