Mathematical statistical software-Eviews is introduced into geotechnical engineering field,based on the data of J2 slope elevation monitoring point in Dong Ming ore,bi-logarithm model,exponential model,linear model,as well as third-order polynomial model are established respectively.With regression analysis,the regularity that how data changes as time goes along is found out.Then,according to relevant hypothesis of statistics and dynamics,with current measured engineering data,time-series model is established and optimized.What's more,the classical ARMA model is upgraded to ARIMA mode,which promotes the approximating and forecasting precision.Based on this model,displacement prediction curve is given and the deformation behavior characteristics are discussed.There is guiding significance in revealing the regularity of slope deformation,as well as in selecting the best protection system.New ideas are also provided for later engineering data analysis and numerical simulation.
