以西安地裂缝为对象,展开了CR-InSAR在地裂缝监测中的应用研究,通过LAMBDA相位解缠得到f3和f11地裂缝2009—2010年垂直形变时间序列,与水准数据的比较发现两者吻合得很好,证明了此方法在地裂缝监测中的可靠性。
Taking the ground fissures in Xi'an are as example,the ground fissures deformation is studied by use of CR-InSAR.Using LAMBDA unwrapping method,the time series of ground deformation information of f-3 and f-{11 fissures are obtained from 2009 to 2010.Comparing with other results,the CR-InSAR data are consistent with leveling results,so it is proved that CR-InSAR is reliable for monitoring the ground fissures.
