Small Baseline Bubset InSAR Technology Used in Datong Basin GroundSubsidence,Fissure and Fault Zone Monitoring

    Abstract
  • Objective Datong basin is one of the geological hazards development zones where geological disasterhas a high frequency,such as the ground subsidence,ground fissure and so on.In this paper,thesmall baseline subset(SBAS)InSAR technology was used to process 40scenes of Envisat SAR datacovering this area,and the surface deformation distribution characteristics were obtained.The timeseries deformation characteristics of the typical subsidence area were analyzed.The relationship amongthe regional ground subsidence,ground fissures and fault were also analyzed.The results show thatthe ground subsidence is influenced by groundwater exploitation and controlled by the faults.At thesame time,the horizontal and vertical activity characteristics of the Locomotive Factory ground fissurewere analyzed,and its relationship with precipitation.
