Abstract

Based on TerraSAR data with high spatial resolution, the GAMMA software was used to obtain the distribution of land subsidence along the region of intercity railway between Beijing and Tianjin. Three-pass differential interferometry technology was adopted to monitor the land subsidence. Results showed that land subsidence is not obvious from March to July 2009 in the study area. The largest deformation during the aforementioned period is 6.14mm, which is around the average value of GPS monitoring.
