摘要

Using the available monitoring data, an expression of vertical deformations with associated coordinates in rock slope was established, in which coefficients were obtained by the least square method. After transforming the expression into the standard form of elliptic umbilic catastrophe model, the stability criterion and initial unstable points for a rock slope were determined with the statistically analysis of this model. Calculations in the proposed elliptic umbilic catastrophe model may present more detailed processes and therefore provide more explaining results than those from the commonly-used cusp catastrophe model. Two case studies, respectively referred to the Ca'di Malta landslide in Italy and the Baiheling landslide in China, show the reliability of the method presented in this paper.
