Application of improved GM(1,1) models to prediction of Slope deformation

摘要

At present, most large strip mines have been in the mid-mining and the mining .with the increase of mining depth，the slope is mounting up steadily, and bigger the slope angle ,worse the slope safety, therefore, it's very important for mining safety production by slope displacement monitoring and stress monitoring, provides a reliable technqlogy data for the analysis of stability of rock slope stability and forecast slope, and get an accurate deformation prediction models.But the original GM (1,1) model was just taking of the gray model formula simply, did not consider whether the deformation accord with the actual, or deal with the original deformation measurements simply. How to make use of the measured data to generate a more regular series, this new generation of original series, a new series of weights are discussed. The formation of free weights given formula in order to model more realistic deformation of the deformation value. This article discussed the weights of regenerate the original series to a new series. Given out the formation formula of free weights in order to produce the deformation values when model more realistic.
