摘　　要：概述了飞燕式系杆拱桥的结构体系及受力特性,以国内某五跨飞燕式系杆拱桥实际工程为例,采用有限元模拟法分析了该桥静力、动力学特性及结构稳定性,并提出了相应设计建议,可为同类桥梁的结构分析和设计工作提供参考。The structural system and mechanical properties of fly-bird-typed tied arch bridges are introduced in brief in the paper.Based on a five-span fly-bird-typed arch bridge,the static and dynamic properties and structural stability are analyzed by FEM simulation,and relevant design proposals are eventually put foward,which can provide reference for structural analysis and design work of the same type of bridges.
