GRAY PREDICTION MODEL OF DEFORMATION OF THE HUANGTUPO LANDSLIDE

The essence of the gray prediction model is to fit the known data sequence with an exponent form to a curve, and then extend the curve to the future in order to predict the unknown data. This paper establishes a GM(1,1) model for prediction of the horizontal displacement of the Huangtupo landslide.Actual application shows that the model is characterized by a high precision and wide applicability.
