Long-Term in-situ Monitoring of Anchoring System and Preliminary Analysis of Monitoring Data. Journal of Earth Science, 2026, 37(2): 740-751. doi: 10.1007/s12583-024-0333-4

The geological environment in which the reservoir slope is situated is intricate, influenced by factors such as precipitation and fluctuations in reservoir water levels. Furthermore, the anchoring structure embedded within the rock mass of the slope undergoes corrosion and deterioration due to these factors, resulting in a highly complex interaction process between the slope rock mass and the anchoring structure. The long-term safety of rock-anchored structure systems is closely tied to the construction and safe operation of reservoirs, as both internal and external factors play a role in ensuring their stability. The present study aims to investigate this intricate issue by designing and establishing an on-site comprehensive multi-field information monitoring platform. The multi-site information monitoring platform comprises three components, namely the landslide monitoring system, anchor structure monitoring system, and data management system. The landslide monitoring system encompasses the surveillance of surface deformation, subsurface deformation, and environmental factors. The monitoring system for anchor structures includes the monitoring of prestress, anchor cable strain, and corrosion status of steel bars. The establishment of a preliminary system for data transmission and management has been accomplished. The current monitoring results indicate that the health condition of the tested anchor cables is satisfactory, and the strain and corrosion status are influenced by the design of the anchor cable structure. The platform is currently undergoing enhancements with the incorporation of cutting-edge anchoring structure design and monitoring equipment.
