摘要：

This contribution explores satellite-based monitoring to evaluate the effects of excavation-induced subsidence on adjacent buildings. A methodology to overcome limitations in retrieving vertical displacement estimates from a single Interferometric Synthetic Aperture Radar (InSAR) measurement by utilising prior information about the subsidence field is proposed. In addition, a damage assessment procedure that accounts for the real building geometry is introduced. The proposed approach is tested on a building influenced by a typical deep excavation. InSAR measurements of two different SAR missions are validated by comparison to levelling data.
