Research on Landslide Deformation Combination Prediction based on IBA-ELM-CT Model and M-K Analysis
In order to effectively grasp the causes of the revival of the old landslide and its subsequent deformation characteristics,based on the geological conditions of the old landslide,an analysis of its revival causes is carried out first.Then,combined with the landslide deformation data,deformation prediction and trend evaluation are achieved through the IBA-ELM-CT model and M-K analysis,in order to fully grasp the subsequent deformation characteristics of the landslide.The analysis results indicate that in the analysis of the causes of the revival of old landslides,geological lithology,topography,and geological structure are inherent factors for the revival of old landslides,while rainfall and human engineering activities are triggering factors for the revival of old landslides.The combined effect of these two factors leads to the revival of old landslides.In the subsequent deformation research results of landslides,the IBA-ELM-CT model has high prediction accuracy,and according to the extrapolated prediction results,the subsequent deformation rate in the middle of landslide is relatively larger,that is,its subsequent deformation rate tends to increase,while the deformation of the rear and front edges shows a decreasing trend;Meanwhile,according to the M-K analysis results,the middle part of the landslide always shows an increasing deformation trend,while the deformation of the rear and front edges shows a decreasing trend indicating that their deformation tends to stabilize.Compared with the predicted results,the analysis results of the subsequent deformation characteristics of the landslide have better consistency,which mutually confirms the accuracy of the two methods and provides a certain reference for landslide disaster prevention and control.
