Abstract

Ground subsidence is an emerging geological hazard in Baotou, Inner Mongolia. Four areas of Baotou with relatively large subsidence range and rate were selected for analysis. Focusing on investigation of ground subsidence using PS-InSAR technology, a total of 43 frames of ALOS PALSAR images yielded a SAR data span from December 2006 to January 2011, allowing ground subsidence scope, subsidence velocity, time-series deformation to be obtained. Major causes and influencing factors of the ground subsidence are closely related to soft soil consolidation and compaction and the decrease in the level of groundwater caused by increased development and utilization of groundwater.
