Using InSAR time series analysis to characterize tunnel-induced ground surface deformation (UTI-UTC 40)

This research project utilizes Interferometric Synthetic Aperture Radar (InSAR) time-series analysis to monitor and characterize ground surface deformation resulting from underground tunneling activities. The primary goal is to enhance the detection and quantification of tunneling-induced settlements and deformations in urban environments. By leveraging satellite radar data from platforms such as Sentinel-1 and COSMO-SkyMed, the study applies Persistent Scatterer (PS) and Small Baseline Subset (SBAS) techniques to detect subtle surface changes over time. These geospatial insights are correlated with construction timelines and geotechnical information to validate the extent and distribution of deformation caused by tunnel boring machines (TBMs). The project demonstrates the viability of integrating InSAR analytics with ground-based measurements to support risk assessment, construction planning, and early warning systems for infrastructure protection in densely built-up areas.
