摘要
桥梁结构的健康监测是桥梁安全的重要保障。基于工程测量原理,对桥梁进行实时的变形监测,是桥梁健康监测的重要研究方向。GPS-RTK技术为桥梁健康监测的实时性提供了可能。从设备方案、安装方案和稳定性试验方案出发,为GPS-RTK应用于桥梁结构健康监测设计了方案,为后续的桥梁健康监测数据采集和健康分析奠定了良好基础。
Health monitoring of bridge structures is an important guarantee for bridge safety. Based on the principle of engineering measurement,real-time deformation monitoring of bridges is an important research direction of bridge health monitoring. GPS-RTK technology provides the possibility for real-time monitoring of bridge health monitoring. Starting from the equipment scheme,installation scheme and stability test scheme,this paper designs a scheme for the application of GPS-RTK in bridge structural health monitoring,which lays a good foundation for subsequent bridge health monitoring data collection and health analysis.
