Based on the principle of time series analysis, this paper introduces the method of time series analysis and the statistical characteristics of time series model and its application in deformation monitoring data processing. It discusses in detail how to use the time series to recognize the model, estimate the parameters and predict the sequence of the process. Combined with the deformation monitoring of the historic buildings in Shanghai, a key project of the Shanghai Municipality, it is verified that the time series analysis has good effects on data fitting and prediction of deformation monitoring and can accurately reflect the changing rules of monitoring points.
