Abstract: Exponential trend model is applied to forecasting the displacement values at observation point GA in Lianziya hazardous rock mass. It is a new method which forecasts the deformation and failure of the slope. At first, nonlinear exponential trend model is linearized, and undetermined parameters are determined using the least square method; and then the exponential trend model without undetermined parameters and displacement values of forecast have been obtained. The errors of the results of forecast and actual displacement values are very little. It shows that this method may be used to forecast the displacement values in the deformation of slopes (landslides); and the effect is good. Finally, the interval and interval length of forecast values are also estimated.

Key words: exponential trend model, slope, displacement, forecast
