The surface displacement by seasonally freezing bulge and thawing subsidence are main hazards for engineering construction in permafrost regions.One of the main problems is how to monitor the frozen ground's displacement in the process of construction and protection of the Qinghai-Tibetan railway.For detecting the subsidence of the frozen earth on Qinghai-Tibetan plateau,this paper improved the technology of Permanent Scatterers and used the method to analysis the deformation at Beiluhe.The results gotten from permanent scatterers method are in concordance with leveling.This proves that it is feasible to using permanent scatterers method to analyze deformation of the frozen earth on the Qinghai-Tibetan Plateau.
