Mapping Urban Excavation Induced Deformation in 3D via Multiplatform InSAR Time-Series (UTI-UTC 27)

This project explores the use of advanced Interferometric Synthetic Aperture Radar (InSAR) techniques to map three-dimensional ground deformations caused by urban excavation activities, particularly tunneling. By integrating time-series data from multiple SAR platforms—including UAVSAR, Sentinel-1, and COSMO-SkyMed—the study constructs a comprehensive deformation field that captures vertical and horizontal displacements over time. These remote sensing datasets are validated and fused with ground-based measurements, such as total station and leveling surveys, to improve accuracy and spatial resolution. The resulting 3D deformation models enable precise monitoring of subsidence and uplift phenomena associated with underground construction, offering valuable insights into the effects of excavation on surrounding infrastructure. The research supports the development of more resilient and data-informed urban planning, tunneling design, and risk management strategies.
