英文摘要	Because land subsidence severely threatens urban buildings, subsidence monitoring of urban buildings is very significant. Using Germanic synthetic aperture radar(TerraSAR-X) images with 1-m spatial resolution and permanent scatterers interferometric(PSI) technique, a subsidence monitoring experiment was conducted to study the subsidence characteristics of different types of buildings (time, height, location) in Tanggu Bohai district and Donggu district. The study shows that the temporal and spatial characteristics of building subsidence vary significantly with different types of buildings in terms of subsidence rate and subsidence time process. The study results can provide scientific reference for the risk control of buildings subsidence in Tianjin Tanggu Binhai New Area.
