STUDY ON DEFORMATION PREDICTION OF IMPROVED SAITO'S METHOD BASED ON VERHULST MODEL

According to the monitoring data of landslide in upside northern district of Shuichang iron mine and Saito's creeping theory,improved Saito's curve with four deformation developing stages for underway landslide of slope with rock mass is put forward.Equations,velocity and acceleration curves of deformation are derived,and failure time forecast model is established based on displacement information.At last,the reliability and precision of the improved Saito's method are verified.
