摘　　要：钢管混凝土系杆拱桥在各类桥梁工程中应用广泛,具有刚度大、跨越能力强、造型优美等优点。传统支架设计中,经过预应力张拉后,系梁与支架能够共同承担施加的荷载,其中荷载包括拱肋支架自重和钢管混凝土自身重力。利用Midas/Civil软件对盘扣式支架-系杆拱和支架-梁柱建立三维有限元模型,研究其在不同施工荷载作用下支架-梁柱和支架-系杆拱的受力特性和变形趋势,总结了在施工后期工况中支架的荷载分布规律,相关研究结论可为实际桥梁工程提供参考。Concrete-filled steel tube tied arch bridge is widely used in all kinds of bridge engineering,which has the ad-vantages of high stffness,strong crossing ability and beautiful shape.In the traditional support design,after the pres-tressed tension,the tie beam and the support can jointly bear the imposed load,which includes the self-weight of arch rib support and the self-gravity of concrete-filled steel tube.Midas/Civil software is used to establish three-dimensional finite element models for disk-buckle bracket arch and bracket beam-column arch.The mechanical characteristics and deforma-tion trends of bracket beam-column arch and bracket beam-column arch under different construction loads are studied.The load distribution law of the support in the late construction condition is obtained,and the relevant research conclusions can provide reference for practical bridge engineering.
