Monitoring the Ground Deformation Caused by Ankara M4 Subway Tunnel with SAR Images

Abstract

Metro line projects are considered essential and costly but necessary projects to reduce and regulate traffic density. However, deformations that are not seen during the construction of the line may occur as time progresses. In this study, an investigation has been provided on how the ground deformations may occur in the future. The study area is Ankara province, Aydınlıkevler district. The data sets used in the study were obtained from ascending and descending Sentinel-1 images. Persistent Scatter Interferometry/Stanford Method for Persistent Scatterers (PSI/StaMPS) was used for interformetry measurements within the scope of the study. The results were compared with real field images
