摘要研究目的：高原冻土的不稳定性使进行冻土区路基变形监测分析极其重要，但受限于高原严酷自然环境条件，当前利用地面现场测量来分析多年冻土路基变形的方法，开展工作极为困难。卫星雷达差分干涉(D-InSAR)技术是近年来出现的无需地面现场测量作业，能够获得大范围地表覆盖区域连续点、线、面沉降信息的一种全新地表变形监测分析方法。针对特殊困难环境下高原多年冻土区路基变形监测与分析问题，讨论利用卫星D-InSAR空间遥测多年冻土区路基表面沉降变形的必要性、可行性和应用研究价值及意义。

研究结论：在青藏高原这种特殊困难的自然地理条件下，采用卫星D-InSAR进行多年冻土区路基变形分析，对改善劳动条件、提高监测效率、减少费用、最大限度地减少极其困难的地面人工测量工作量，能起到明显的积极作用，对于高原冻土区国家重要基础设施长期监测系统建设有重要工程现实意义；利用D-InSAR获得的独特路基地表变形信息，可实现从大范围连续点、线、面3种角度，分析高原冻土路基变形的时空特征和规律，有望从空间全局的分析角度获得冻土路基变形新发现或新知识，从而为冻土路基稳定性评价提供新的科学依据，也为更深入地研究冻土工程变形开拓新思路。

Abstract：Research purposes：It is very important to monitor the subsidence of subgrade in permafrost region because the permafrost is unstable , but it is difficult to monitor the subsidence of the subgrade in permafrost region using the current ground measuring device due to the extremely bad environmental conditions. The satellite differential interferometric synthetic aperture radar technology(D-InSAR) is an innovative measurement method developed rapidly in recent years. This approach can cover and measure a region of hundreds of square kilometers without on-site fieldwork. The subsidence information of point, profile and surface can be acquired and analyzed using this method. In the paper, the necessity, feasibility and significance of monitoring the subsidence o f subgrade in permafrost region using satellite D-InSAR technology are discussed.

Research conclusions：Under extremely difficult natural geographic condition, using the satellite D-InSAR technology to monitor the subsidence of the subgrade in permafrost region is essential to improve the working condition, enhancing the monitoring efficiency, reducing the monitoring cost and manualm on itoring work in difficult area as much as possible and to the construction of the long-term monitoring system for the infrastructure in permafrost region. Using the unique, continuous subsidence information of point, profile and surface obtained from the satellite D-InSAR can analyze the spatial characteristics and regulation of the subgrade deformation in permafrost region from the angles o f points, profiles and surface in the wide range and can help obtain the new discovery or new know ledge about subgrade subsidence in permafrost region through the analysis from the spatial angle. These can provide the new basis for evaluation of the stability of the subgrade in permafrost region and open the new thought on further researching the engineering deformation in permafrost region.

Key words： SAR remote sensing interferometry subgrade subsidence deformation monitoring
