| Abstract: | Advances in applying the nonlinear dynamic system (NDS) to the stability evaluation of slopes (rock planar-slip slope and soil circular-slip slope) and prediction of landslides are presented in this paper. This paper includes: constitutional equation of medias in the sliding surface, instability criterion, function of water, theoretic explanation of creep phases (three phases), physical prediction model for landslides, prediction parameters and modeling of chaos model, etc. Finally, the orientation further studies in this field are pointed out. |
