摘　　要：主要采用有限元方法对下承式系杆拱桥进行了空间受力分析。分析结果表明拱桥整体受力合理,力学承载性能良好。同时,对拱脚和系梁连接节点处进行了结构优化,解决了拱脚处受力复杂的问题。The finite element method is adopted for dimensional force analysis of the through tie bar arch bridge, the results from which indicate that the overall arch bridge is subject to the force reasonable, with good performance of mechanical bearing. Meanwhile, the connecting nodes of the arch foot and the tie bar are structurally optimized to solve the problem of complicated forces on the arch foot.

关 键 词：下承式拱桥 空间分析 拱脚
