IBIS-L 是干涉测量、SAR 技术及步进频率波的结合体，目前在地表微变形监测中应用非常广泛，但其应用于滑坡形变监测中的实例较少，且缺少统一的监测及数据处理方法。以西南地区白水河滑坡为监测对象，在初步认识该滑坡的地质原型的基础上，利用 IBIS-L 开展了滑坡地表变形监测。重点介绍了 IBIS-L 开展滑坡变形监测的过程及数据处理的方法，分析了白水河滑坡在监测期的变形特征。最后将本监测与滑坡变形特征的数值计算结果作了对比，结果显示利用地微变远程监测系统对滑坡开展地表变形监测是可行的。

Geological monitoring as an effective technique of disaster prevention,has engineering significance for the monitoring of landslide deformation.IBIS-L (Image by Interferometric Survey)is an integration of interferomet-ric survey,SAR technology,and stepped frequency wave.It is widely used in the monitoring of ground surface mi-cro-deformation,but less applied to landslide deformation monitoring and in lack of unified monitoring and data pro-cessing method.A landslide in southwestern China was taken as an example and was monitored using this method based on preliminary geological understandings of the landslide on the prototype.The approaches of monitoring process and data processing are described in emphasis,and the deformation behavior are analysed.Comparison be-tween the monitoring result with numerical simulation result verifies the feasibility of this IBIS-L system.
