Application of Time Series in Constructing Subgrade
Xia Yin · Soil Engineering and Foundation · 2007
Mathematic models are established with time series for the passivity of expressway construction. The unrest surface's settlement is converted into rest settlement velocity by dealing with simple difference (d=1), namely the unrest time series ARIMA(p, d, q) model is transformed to rest ARMA(p, q) model. ARMA(1, 1) model is established to forecast the settlement during constructing subgrade and the time for next load. The forecast results are precise and reliable, and can reflect the distortion characteristics during constructing subgrade.
