Deformation Analysis and Reinforcement Effect Evaluation for the No. 65 Slope on the Shangsan Expressway Based on SBAS-InSAR

Buildings
The deformation of the No. 65 slope on the Shangsan Expressway poses a potential threat to road safety. In July 2021, the deformation rate of this slope accelerated significantly, leading to the implementation of reinforcement measures in 2022.

Spatiotemporal Evolution and Drivers of Highway Surface Deformation Based on SBAS-InSAR and Geodetector. [PDF]

Sensors (Basel)
To address the lack of long-term, wide-area surface deformation observations along the geologically complex Dangxiong–Yangbajing section of the G6 Expressway in the frozen-ground region of the Qinghai–Tibet Plateau, where conventional monitoring is insufficient, we applied Small Baseline Subset Interferometric Synthetic Aperture Radar (SBAS-InSAR) to ...

Detection and assessment of potential landslides in the Xiaojiang River Basin using SBAS-InSAR. [PDF]

Sci Rep
The Xiaojiang River Basin is susceptible to debris flows and landslides due to its unique geological environment and historically frequent human activities. For large-scale landslide identification, traditional ground-based surveying techniques are insufficient due to limitations in data acquisition and operation capabilities. Interferometric Synthetic
