Abstract To effectively grasp the reactivation characteristics and deformation laws of an ancient landslide, based on the on-site investigation results of the landslide area, we analyze the reactivation deformation characteristics, and then use the WPT-ROA-RVM-CT model for landslide deformation prediction. The results show that after heavy or continuous rainfall, the surface cracks of landslides are relatively developed, with tensile and shear properties. The landslide exhibits obvious displacement characteristics, that is, the deformation of the middle and rear edges of the landslide are significantly greater than that of the front edge. The deformation direction has a counterclockwise variation, fully indicating that the reactivation deformation characteristics of ancient landslides are significant. Meanwhile, through deformation prediction, the WPT-ROA-RVM-CT model is verified to have high prediction accuracy. Through extrapolation prediction, we find that the subsequent deformation rates of landslides are all positive and large, indicating that the subsequent deformation of landslides will further increase, with a significant risk of instability. Therefore, disaster prevention and control research need to be carried out as soon as possible.
