Abstract: Slope deformation is a complex systematic process. Single point model named GM(1,1) can’t consider correlation of the deformation between the discrete monitoring points. The method of determining dynamic weight is presented; and the new weighted multi-point grey model named WM-GM(1,1) forecasting the slope deformation is established by analyzing the shortcoming of GM(1,1) which can’t acquire the appropriate background value. A case study based on the Matlab program shows that the forecast result of WM-GM(1,1) is more precise than that of the GM(1.1).

Key words: high rock slope, deformation monitoring, background value, dynamic weight, WM-GM(1,1)
