Abstract In order to understand the deformation evolution characteristics of toppling deformation bodies in deep-cut river valleys of southwestern China，this paper presents a case study of the Yagong toppling deformation，located near the spillway outlet of a large hydropower station in the Upper Lancang River. Based on field investigation，the SBAS-InSAR technique was used to analyze 53 scenes of ascending Sentinel-1A SAR images from January 2021 to April 2023. Combined with high-definition satellite images，high-resolution digital elevation data，surface deformation monitoring and rainfall data，an in-depth study of the deformation characteristics and evolution mechanism of the Yagong toppling deformation was carried out. The results indicate that：(1) The Yagong toppling deformation is currently in a continuous acceleration stage，with an annual deformation rate ranging from －49.96 mm/y to －0.70 mm/y during the SAR image period，and a cumulative maximum deformation amount of －106.97 mm. The areas of extremely strong and strong deformation are primarily concentrated in regions above 2 400 m a.s.l.，accounting for as much as 42.75% of the total affected area. (2) The monthly average surface deformation during the rainy season is 1.71 times greater than that of the dry season，highlighting that continuous rainfall is one of the most prominent factors in promoting slope deformation development. (3) Controlled by the incision caused by the Lancang River and Mushui River，as well as variations in geological structures and lithology，the toppling deformation shows significant temporal and spatial differences. This primarily manifests as increasing surface deformation with altitude，and greater deformation on the flank of the Lancang River compared to the flank of the Mushui River. (4) The presence of the basalt in the middle part of the slope effectively reduces the overall deformation rate of the underlying slate and sandstone. The soft-hard-soft rock distribution in the study area plays a crucial role in enhancing slope stability.
