Hysteresis effect and seasonal step-like creep deformation of the Jiuxianping landslide in the Three Gorges Reservoir region

H Yang, K Song, L Chen, L Qu - Engineering Geology, 2023 - Elsevier
Slow-moving landslides are common in the Three Gorges reservoir (TGR) region. It may
evolve into massive landslide hazards due to reservoir level fluctuation and rainfall. The …
