APPILICATION OF TIME SERIES ANALYSIS METHOD TO MEASURED DISPLACEMENT IN TUNNELING
时间序列分析在隧道施工监测中的应用

A more general time series associate model is used to describe the variation regularity of monitoring results for tunneling. The accuracy and reliability of displacement prediction can be improved with this model. In this model, the mean of data variation with time can be described by polynomial or exponential expression, and the stable process of zero mean by random process model AR(n) or ARMA(n, m) . The release displacement of tunnel before the first measurement is estimated with this model, and the method is checked by engineering example.
