Subsidence and Deformation Data Module

Geological instability can lead to differential movement of the ground, which in turn impacts the safety of various infrastructure such as urban roads and energy/power facilities.

The subsidence and deformation monitoring data suite of TerraQuanta is based on InSAR measurement technology to capture surface deformation. Compared with conventional measurement techniques, InSAR technology provides all-weather deformation measurements that does not require any on-site installation, and has the advantages of wide monitoring range, high sensitivity, traceability, adaptability. Non-contact precise measurement can be carried out to identify the risk of early-stage geological disaster.

Subsidence Monitoring of Highway Subgrade

💡 In an expressway operation scenario, abnormal deformation of roadbed can be captured through normalized deformation monitoring, so as to carry out early treatment of minor conditions and reduce long-term road maintenance costs.

Monitoring of Tunnel Entrances and Surrounding Environment

💡 The top of the tunnel and tunnel entrances are critical points to expressway monitoring. InSAR technology is used in identifying deformation abnormalities in surrounding areas of tunnel entrances. As a result, landslide hazards can be discovered early to protect safety of personnels and properties, as well as ensuring the traffic rate of the road.
