Abstract
Summary
Satellite radar interferometry (InSAR) has become an operational tool for monitoring tunnelling projects and other engineering works in urban areas. The technique is a remote sensing approach for measuring ground displacement from satellite radar images and has applications in all phases of tunnelling projects, including planning, construction and operation/maintenance.
In this study, we describe a recent case study where InSAR was applied during the construction of a twin tunnel in Sicily, Italy, where significant ground surface settlement occurred during TBM excavation.
