Application of Curve Fitting and Auto Regression Model to Distortion Monitoring in Subway
Yanfang Li · Surveying and Mapping of Geology and Mineral Resources · 2009
The curve fitting and Auto-Regressive is the commonly used method for distortion monitor data analysis,this article introduced how to establish the curve fitting and the Auto-Regressive model,as well as the adaptability examination of these two kinds of model,and established curve fitting and Auto-Regressive model separately unifies the data of Settlement distortion of some subway shaft surface in Wuhan,for analysising and examinating the result of the Settlement forecasting,and having realized the automation of settlement forecast with the procedure.Through the comparison of experiment,the result indicates that although these two kinds of models basically can satisfy the request for distortion monitoring in the relatively steady distortion,forecast residual of the Auto-Regressive model must be smaller than the curve fitting model.
