The Application of GNSS in Slope and Bridge Displacement and Deformation Monitoring

2025-11-10

 

For a long time, mountainous areas in our country have been negatively affected by slope geological disasters. Currently, the common monitoring method is optical monitoring, which requires manual measurement and has poor efficiency and real-time performance. The new type of automated monitoring system (GNSS) has effectively solved this problem. GNSS have a vital role in the displacement deformation monitoring, not only can improve monitoring efficiency, also can all-weather work stability, low requirements for bridge structure and slope topography. Meanwhile, its high-precision data and real-time transmission and analysis capabilities also provide important technical support for promptly grasping the changes in slope displacement and ensuring safety.

 

Product brief introduction

 

The JMBD-1050 GPS Remote Displacement Measurement System is a brand-new generation of GPS (full system) remote displacement measurement system launched with high-performance and high-precision SoC chips. It supports high-precision positioning with multiple frequencies across the full system, and its signals support satellite signals from China's Beidou BDS B1/B2, the United States' GPS L1/L2, Russia's GLONASS L1/L2, and Europe's Galileo E1/E5b. Composed of one or more positioning devices, the system is installed at monitoring points of engineering projects to measure their horizontal and vertical displacements. This system is an all-weather, unattended, and automated position measurement system. It is widely used in the precise measurement of relative displacement changes in structures in engineering fields such as slopes, high-speed railways, bridges, buildings, mines, and dams.
