Landslide Deformation Prediction Based on Historical Slope Displacement Monitoring Data
According to the optimal weighted combination theory and considering several mathematical models adapted to different curve characteristics,the optimal weighted combination model is established to predict landslide deformation.Based on the analysis of actual landslide monitoring data,the data fitting accuracy and prediction accu-racy of single model and combined model are analyzed and compared.According to the residual of fitting data,the fitting accuracy of optimum weighted combined model is the highest in any single model,and the predicted value is in good agreement with the actual value.Therefore,the weighted combination model can improve the prediction ac-curacy of landslide deformation in the near period,and the prediction data can be used for landslide impending warning.
