TRE Altamira is at the World Tunnel Congress 2022
to present InSAR for Tunneling Operations
Tunneling and civil engineering groundwork activities are constantly increasing due to urban development. Ground excavation activities, especially in highly urbanized areas, can lead to potential geohazards due to ground settlement associated with tunneling activities.
InSAR data is crucial to help assist in determining the extent and origin of ground instability, as well as monitor the surface-level impact of groundwork along the alignment and in the surrounding areas.
Satellite data provides useful information on 1) ground settlement trends prior to operations; 2) surface movement during tunneling operations - to assess the correlation between tunneling and surface displacement; and 3) post-excavation stability - to detect possible residual subsidence that might impact infrastructure.
Spatially dense and precise results
Non-invasive and scalable technique
Completely remote, satellite InSAR is unrivaled in its ability to obtain displacement measurements over large or small areas.
