Abstract：To accurately grasp the landslide deformation potential in the reservoir area, based on the statistics of deformation monitoring results, we use the limit displacement criterion to analyze the landslide deformation potential. Based on the theory of relevance vector machine, we apply optimization processing to ensure the optimum parameters. We build a prediction model of landslide deformation and evaluate the development trend of landslide deformation potential based on the prediction results. Combined with results of the two analyses, we realize the comprehensive landslide deformation potential analysis. The results show that there are some differences in the deformation potential of different monitoring points. According to the disadvantage principle, the deformation potential level is grade IV, and the potential degree is serious. The deformation potential will continue to increase and tend to develop unfavorably. Based on the two analysis results, the landslide deformation potential is in a disadvantageous state, and the possibility of instability in the later period is relatively large. Therefore, disaster prevention and control should be strengthened to avoid disaster losses.
