Abstract:
Based on the deformation monitoring data of a rock slope from 2002 to 2011 and the geological and meteorological conditions of the area, "PauTa" rule was used to select the effective monitoring data, and the GM (1,1) model and trend curve prediction model were developed. The optimal weighted combination model of slope deformation was established based on the optimal weighted combination principle. The combination model was used to predict the slope deformation. The comparison between the predicted and actual deformation trend suggested that the prediction accuracy of the combination model is higher than that of any single model, and therefore the combination model is more reasonable and reliable.
