本文以江阴大桥结构健康监测系统升级改造工程为研究背景,在对江阴大桥结构受力特点进行简要分析的基础上,从大跨桥梁结构健康监测的监测思想、测点布置、测试技术的应用等方面,对江阴大桥原安全监测系统及存在的主要问题进行了分析研究。并从项目选择、传感器的布设、网络结构、数据采集、监测运行模式、数据存储、应用软件设计等方面对江阴大桥原结构安全监测系统进行了比较详细的设计分析与反思。为升级改造工程设计与实施提供了依据。
Based on the brief analysis of the structural characteristics of Jiangyin Bridge, this paper takes the Jiangyin Bridge structural health monitoring system upgrading project as a research background, from the monitoring idea of the long-span bridge structure health monitoring, measuring point layout, the application of testing technology Aspects, the original safety monitoring system of Jiangyin Bridge and the main problems are analyzed and studied. And the detailed design analysis and reflection on the original structural safety monitoring system of Jiangyin Bridge are made from the aspects of project selection, sensor deployment, network structure, data acquisition, monitoring operation mode, data storage and application software design. For upgrading engineering design and implementation provides the basis.
