Abstract: Abstract The stability of side slope is very important to the construction and operation of high-speed railway. In this study, we proposed to jointly apply Interferometric synthetic aperture radar (InSAR) and BeiDou Navigation Satellite System (BDS) techniques to identify and monitor side slope along the Changgan high-speed railway. Deformation information along the Changgan high-speed railway was firstly derived by time-series InSAR (TSInSAR) using 68 Sentinel-1A SAR images spanning September 2019 to December 2021 for side slope identification, and then the identified unstable side slope (i.e., Xiahen side slope) was jointly monitored and analyzed by TSInSAR, BDS and unmanned aerial vehicle (UAV). The results show that: (1) TSInSAR can effectively identify unstable side slope, and monitoring results of side slope obtained by TSInSAR and BDS showed good agreement. (2) A large subsidence bowl was identified in the Xiahen side slope, and the maximum subsidence velocity reached − 57 mm/a. (3) Side slope stability was related to side slope treatment. The rainfall change was one of the important factors that affected the deformation of the Xiahen side-slope. The subsidence mainly happened in the rainy season, and a certain lag effect was observed in the subsidence change. (4) Geological structure had a certain influence on side slope deformation.
