高精度BDS/GPS变形监测技术在桥梁监测中的应用研究

Application research of high precision BDS/GPS deformation monitoring technology in bridge monitoring

随着北斗导航系统的不断发展完善,北斗与GPS组合技术将被应用于更多领域。桥梁作为交通的重要组成部分,在长期使用过程中,受到自然环境以及人为的影响会使桥梁结构发生损伤,因此对桥梁进行变形监测是必不可少的一项内容。文中以国内某大型桥梁变形监测实例为背景,利用BDS/GPS高精度变形监测技术对其进行监测,分析BDS/GPS组合技术相比单系统技术具有的优势以及其在变形监测应用中的原理与方法。

With the continuous development and improvement of Beidou navigation system, Beidou and GPS combination technology would be applied to more fields. As an important part of transportation, the structures of bridges were damaged by the natural environment and human influence during the long-term use. Therefore, deformation monitorings of bridges were the indispensable part. Based on the example of a large-scale bridge deformation monitoring in China, in this paper, it was monitored using BDS/GPS high-precision deformation monitoring technology, and the advantages of BDS/GPS combined technology and the principle and methods were analyzed in deformation monitoring applications comparing with single-system technology.
