Horizontal deformation of the deep pit is a dynamic process.During the excavation and construction,a dynamic combined prediction model,in which curve fitting theory and time-series analysis model is adopted,is established on the basis of measured data.With the addition of new deformation datum,the model parameters are continuously modified.The model is not asked to consider complex factors the deformationof.The practical research has showed that the error between measure and prediction value is mostly below 5 percent in short-term.The model is more appropriate in the pit of deformation measurement and prediction.
