Settlement deformation often happens on foundations and structures due to the influence of pressure accumulation and foundation destabilization in tunneling engineering,pit engineering and mining engineering.Settlement deformation monitoring and prediction must be done to ensure engineering safety.Due to the complexity and variety of the settlement influencing factors,correlations between monitoring data are ignored in commonprediction models.On the other hand,the time series analysis method is a dynamic prediction method which takes into account the correlations between monitoring data,so a prediction method for settlement monitoring is proposed basedon time series analysis in this paper.Three common time series models are studied at first and then the modeling process which includes stationary test and model selection is given.Finally,the practical application shows thefeasibility and veracity of this approach.
