Slopes are slopes on the side of a mountain or on the edge of the earth that are prone to become unstable due to natural and man-made factors. Monitoring the stability of slopes can prevent disasters such as landslides and protect people and property.
Surface displacement monitoring is a key technology for assessing the stability of slopes, and it provides direct observation data for deformation monitoring systems. The BeiDou Global Navigation Satellite System (GNSS) has become an indispensable tool in slope displacement monitoring with its excellent accuracy and efficiency. Among many monitoring techniques, GNSS displacement monitoring is favoured for its wide applicability, and static relative positioning techniques are usually used to achieve accurate measurements.
BeiDou GNSS technology is known for its high positioning accuracy, which can meet the strict requirements for accuracy in slope displacement monitoring. By deploying GNSS displacement monitors, monitoring stations can continuously receive signals from satellites and calculate the 3D coordinate changes of monitoring points in real time. These coordinate change data can accurately reveal the displacement status of the slope, providing engineers with instant slope stability information. Compared with the traditional monitoring means, Beidou GNSS technology not only has higher accuracy, but also has a wider coverage, which can evaluate the stability of the slope more comprehensively.
BeiDou GNSS slope displacement online monitoring technology can continuously collect a large amount of data, providing engineers with rich monitoring information. In-depth processing and analysis of these data can refine key information, such as the displacement speed and direction of the slope, and then predict and evaluate the displacement dynamics of the slope. The acquisition of these data is essential for slope maintenance and management, and can help engineers to develop more scientific and effective decision-making strategies.
