Abstract：According to the characteristics of deformation data and noise propagation on wavelet transforming in various scales，a new threshold estimation method and threshold processing function are proposed，and applied to establishment of time series model for deformation observation data.The advantage of improved wavelet denoising method is demonstrated，and the precision of prediction value is higher than that with the conventional methods.
