摘要
以青藏铁路拉萨段为试验区,利用DInSAR技术和Palsar数据监测得到了该地区的冻土形变,对形变图的分析表明,其形变非常吻合冻土冻胀融沉的物理变化规律,说明DInSAR技术适合在青藏高原大范围内监测冻土形变。
The Lasa section of the Qinghai-Tibet 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 Qinghai-Tibetan plateau.
