摘　　要：为有效保证某型装配式钢桥使用过程中的安全性,以某型装配式钢桥为研究对象,以ABAQUS软件为技术平台,建立了某型装配式钢桥动态特性分析的数学模型,得到了钢桥的固有频率及振型,同时分析得出了钢桥的结构薄弱环节和使用过程中避免桥梁共振的措施。In order to effectively ensure the safety of a fabricated steel bridge in the use process,taking a fabricated steel bridge as the research object and ABAQUS software as the technical platform,the mathematical model for the dynamic characteristic analysis of a fabricated steel bridge is established,the natural frequency and vibration mode of the steel bridge are obtained,and the structural weakness of the steel bridge and the measures to avoid bridge resonance in the use process are analyzed.It provides technical guidance for structural optimization and safe use of a fabricated steel bridge.
