Temporal and spatial relationships between the ground displacements and dewatering activities during tunneling in Frankfurt am Main
Technical Paper
This paper presents the results of a Sentinel-1 InSAR analysis of ground displacements during the construction of a subway tunnel in Frankfurt am Main, focusing on the temporal and spatial relationship between displacements and dewatering activities.
Discover how Sentinel-1 InSAR data offers valuable, compatible insights that enhance and validate traditional ground-based monitoring for tunnel construction projects.
Gain an understanding that the cumulative settlement in Frankfurt clay during dewatering may be less than 80% (often 70%) in the first six months, contradicting some earlier empirical studies.
See how InSAR displacement estimates often report higher settlements than ground-based leveling methods, potentially due to the different reference networks used in field studies.
Learn about the critical role of geological features, such as a fault controlling the groundwater table, in limiting and distributing the ground displacements caused by dewatering.
Understand that InSAR is a powerful tool for identifying geological hazards, locating potential weaknesses in ground-based monitoring, and improving subsurface displacement modeling.
