Abstract：Taking the ground fissures in Xi’an are as example, the ground fissures deformation is studied by use of CRInSAR.Using LAMBDA unwrapping method, the time series of ground deformation information of f3 and f11 fissures are obtained from 2009 to 2010.Comparing with other results, the CRInSAR data are consistent with leveling results, so it is proved that CR-InSAR is reliable for monitoring the ground fissures.
