Research of Time Series Model Method in Metro Structure Deformation Prediction
Wang Bi · Modern Surveying and Mapping · 2014
The paper bases on deformation monitoring data of one tunnel's structure of Nanjing Metro,and establish model by using regression analysis method and time series method respectively,in order to predict the deformation of metro structure.In this engineering projects,the prediction precise of regression analysis model is about ±0.20 mm,while time series model's prediction precise is about ±0.08 mm,increasing 60% over regression analysis model.It shows that time series model can predict the deformation of metro structure better.
