Application for Deformation Monitoring of Time-series Analysis
Yun-Yun Wu · Jiangxi kexue · 2011
In this paper,the basic principle of time series analysis and the procession of it using in the deformation were introduced first.The modeling procedure of time series analysis was detailed intrduced,which contions data pre-processing,Selection of the Model,order estimation,confirmation of model parameters and the reliability.Two formulars for forecasting of ARMA and ARIMA are briefly introduced in this paper.At last,A slope observation of a city was tackled using the time series analysis.The result shows that the precision of the time series analysis untilyling in the stackling of some simple deformation series is very high.In addition the error absolute values of the nine periods were under 0.18 mm.At the same time,compared with other methods of data handling,the modeling procedure of time series analysis is simpler.It is an effective way to handle the dynamic data.
