结合江阴大桥上部结构健康监测系统升级改造工程,依据大桥的结构特点与各组成部分的监测需求,进行基于大跨径桥梁管养需求的实用型结构健康监测系统的总体目标、系统框架、层次结构和系统构成的设计。并借助于该系统提供的及时、客观的数据,将监测取得的成果成功应用于主桥阻尼器安装评价、主梁受船撞击后的损伤状况评估、大桥结构模态和动力特性分析等具体养护管理工作中,从而为江阴大桥的日常管养提供了定量化依据和科学化指导。
According to the structural characteristics of the bridge and the monitoring requirements of each component, combined with the upgrading and reconstruction project of the superstructure health monitoring system of Jiangyin Bridge, the overall objective, system framework and hierarchy of the practical structural health monitoring system based on the long- And the system constitutes a design. With the help of the timely and objective data provided by the system, the successful achievements of monitoring have been successfully applied to the evaluation of the installation of the main bridge damper, the damage assessment of the main girder after being hit by the ship, the concrete modal and dynamic analysis of the bridge structure Management work, so as to provide a quantitative basis and scientific guidance for the day-to-day custody of Jiangyin Bridge.
