摘　　要：桥梁在其运营期内遭受各种不利的影响,其结构的安全性成为桥梁运营管养的关键。近年来,随着电子技术的发展,桥梁健康监测系统得以广泛应用,而在桥梁的健康监测与健康评估过程中一个能够准确反映桥梁特性的基准有限元模型成为关键。基于某桁架拱桥的健康监测系统的振动监测数据,对建立的初始有限元模型进行修正,得到更符合桥梁真实状态的基准有限元模型[1]。The bridge suffered various adverse effects during its operation period,and the safety of its structure has become the key to bridge operation and maintenance.In recent years,with the development of electronic technology,bridge health monitoring system has been widely used,and in the process of bridge health monitoring and health assessment,a benchmark finite element model that can accurately reflect the characteristics of the bridge has become the key model.Based on the vibration monitoring data of the health monitoring system of a truss arch bridge,the initial finite element model is revised to obtain a baseline finite element model that is more in line with the true state of the bridge[1].
