摘　　要：介绍了以多年边坡位移监测资料为基础预测滑坡时间的２种方法。第１种是根据位移时间曲线从等速蠕变阶段转入加速阶段的位移速率作为滑坡临界速率的方法；第２种是用时间序列分析法，根据前几年位移规律预测后几年位移发展趋势，并用国内外滑坡实例确定的滑坡位移速率作为滑坡判据的方法。用这两种方法。Two methods are described to predict landslide of slopes. The first method is based upon the displacement monitoring data of slopes. When the displacementtime curve changes from an increasing stage of constant rate into accelerating stage, the critical displacement rate of landslide is found. The second method uses analysis method of time sequences to predict the development tendency of displacements in coming years according to the displacement law in the past years. Prediction of both time and displacement rate of landslide made in one year before landslide is well coincident with the real situation.
