Abstract:We use the cusp catastrophe model to evaluate the stability of landslide. Then we construct the combined landslide prediction model based on ensemble empirical mode decomposition, GM (1,1) model and support vector machine. The analysis of Biandianzhan landslide shows that the catastrophe characteristic values of each monitoring point are greater than 0, that is, they are in a stable state. The average relative error of the prediction results is small, which verifies the applicability of the prediction model. Through extrapolation prediction, the landslide deformation will be further increased and the stability will get worse.
