Abstract：The Lasa section of the QinghaiTibet railway was selected as a test region.The deformation of frozen ground in the test region were successfully monitored with DInSAR.Through the analysis of the deformation,it is found that the deformation conformes to the law of physical changes of frozen ground,frost heave and thawing settlement.It is shown that DInSAR technique has good prospects in deformation monitoring for the frozen ground in QinghaiTibetan plateau.
