On the basis of displacement - time series of the slope, a nonlinear dynamic model is set up according to backus generalized linear inversion theory in this paper. due to the equivalence beween autonomous gradient system and catastrophe model, a standard cusp catastrophe model can be obtained through variable substitution. the method is used in analysis of displacement data of huangci landslide and wolongsi landslide and in understanding how slopes evolve before sliding. the result shows that the nonlinear dynamic model can make satisfactory prediction result. is it most important that there is a sudden fall of d, which indicates the occurrence of catastrophe ( when d = 0 )
研究表明，滑坡變形失穩過程具有混沌和分維特性，可以用分形理論來研究滑坡預測問題，基於對任一連續函數，至少在較小的鄰域內可以用多項式任意逼近的數學理論，運用改進的backus廣義線性反演理論，以斜坡位移時間序列為基礎，反演了斜坡演化的非線性動力學模型。並利用自治梯度系統與突變模型的等價性，通過變量代換得到標準的尖點突變模型。
