摘要：

With the development of expressway construction and transportation, expressways monitoring are important to ensure the safety and stability of transportation. The Small Baseline Subset Interferometry Synthetic Aperture Radar (SBAS-InSAR) technology provides us deformation information, to prevent potential danger. In this paper, we selects Ningwu Expressway in Anhui Province as the study area, using a total of 136 scenes of Sentinel-1A image data from Jan. 2016 to Dec. 2020 to deformation monitoring. The results shows that a total of six hidden sections were identified, of which the maximum annual average deformation rate was - 32 mm/year. Then we chooses three typical slopes and two tailings dam along as key monitoring areas, shows that the Yanshanao tailings dam settlement is the largest, and the maximum deformation reaching 188 mm. This study provides a reference case for expressway deformation monitoring along the side slopes.
