Description

Technical Field

[0002] Geological disasters often cause ground deformation and surface cracks. To determine the stage of a geological disaster, continuous monitoring of these cracks and data collection are necessary. Currently, the main methods for monitoring surface cracks are manual measurement and automated instrument monitoring.

[0003] Automated monitoring mainly uses instruments that can autonomously and continuously measure and record the changes of cracks over a period of time, thus clearly reflecting the trend of crack changes. The instruments have high recording accuracy, but they are expensive and require advanced monitoring technology, which cannot meet the needs of many building deformation monitoring.

[0004] Manual measurement mainly involves visual inspection or periodic measurement with a measuring tape after setting fixed points manually. The trend of crack change is analyzed based on the measurement results.

[0005] For newly emerging geological disasters, it is impossible to carry out automated monitoring in a timely manner, and manual measurement is often used. However, due to limitations such as the quality of the installation of the monitoring points and the measurement tools, the accuracy of data collection is poor, and the accuracy of data from different monitoring points is inconsistent, which cannot effectively support the prevention and control of geological disasters.
