The forecasting model of exponential smoothing is applied to predict the displacement values at observation point GA of Lianziya hazardous rock masses in this paper. According to the characteristics of observation values, forecasting formula with linear trend of the twice exponential smoothing, appropriate formulae calculating smoothing coefficients and suitable smoothing constant value are selected and used to make a prediction. The forecasting result shows that the errors between the forecast values and the observation values are very little. It also indicates that this model may be well applied in the forecast of the displacement in the deformation of the slopes.
