桥梁变形三维自动监测技术的研究

Research of Threedimensional Automatic Monitoring Technique for Bridges Deformation

为了解决桥梁的整体性形变监测问题,笔者及研究小组引进了GPS-RTK技术和测量机器人技术,在近5年的桥梁整体安全性自动监测工作中取得了显著的工作成效,有效地实现了对桥梁整体安全性的实时监测,其桥梁整体空间位移的三维监测精度可达到亚毫米级。文章叙述了GPS-RTK技术和测量机器人技术应用于大型公路桥梁整体性安全三维原位监测的实施过程、监测要领和数据处理方法。

To resolve the monitoring of bridge＇s entire deformation, the research group and the author have introduced GPS-RTK technique and measuring robot technology, which has made obvious effects in the integration safety surveying of the bridge in recent 5 years, and realized effectively real time monitoring on the comprehensive safety of the bridge, and the precision of three-dimensional monitoring on the whole bridge displacement reaches to sub millimeter level. The article describes the three-dimensional surveying process, surveying essentials and data processing methods on the comprehensive safety of the large roads bridge by GPS - RTK technique and measuring robot technique.
