doi:10.3969/j.issn.1674-0696.2014.05.20

Abstract

Abstract: Grey system theory was used in the data analysis of landslide dynamic monitoring, and Grey Renewal GM (1, 1) Model was proposed to forecast the landslide. Least square was used to get the parameters of Grey Renewal GM (1, 1) model. Test methods were given to inspect the accuracy of the proposed model. According to the measured data of actual landslide, the analysis and prediction results of Grey Renewal GM (1, 1) model were compared with those got by the traditional GM model. Comparison results show that the Grey Renewal GM (1, 1) model is better than the traditional GM model in accuracy, fitting data and forecasting data.

Key words: environmental engineering;landslide, dynamic monitoring, Renewal GM (1, 1) model, prediction
