Strength reduction technique (SRT) is applicable in evaluating the stability of slope in most cases
because it doesn’t need to assume the location and shape of failure surface. But SRT considers only the elastoplastic properties of rock and soil media
neglecting the rheological property. Rheology is basic mechanical property of rock and soil medium. Having some relations to rheology
many slopes occur large deformation or even lose stability in fact. Based on SRT
the effect of rheology on slope deformation and stability is analyzed. The final research shows that the rheological properties of rock and soil media make deformation of every point more large; furthermore it makes slope more dangerous.
