摘　　要：为研究某主跨360m的中承式钢管混凝土提篮拱桥拱肋施工阶段的受力和稳定性情况,文中采用Midas Civil软件建立了该桥拱肋施工阶段的有限元模型,对各工况下拱肋的应力、竖向位移和稳定性进行了分析。结果表明:该桥的施工阶段拱肋应力、竖向位移和稳定安全系数均满足要求,具有较高的安全储备。In order to study the stress and stability of the arch rib of a half through concrete-filled steel tubular basket arch bridge with a main span of 360m, the finite element model of the arch rib construction stage of the bridge is established by using Midas civil software, and the stress, vertical displacement and stability of the arch rib under various construction conditions are analyzed. The results show that stress,vertical displacement and stability safety factor of the arch rib meet the requirements and have high safety reserve.
