New quantitative displacement criteria for slope deformation process: From the onset of the accelerating creep to brittle rupture and final failure

Two quantitative displacement criteria for slope deformation were deduced through the combination of a one-dimensional renormalization group model and the strain-softening constitutive model of geological materials. The criteria can be used to understand the mechanical process from the onset of the accelerating creep on a slope, through brittle rupture, to the final failure and landslides. The study showed that according to the first criterion,...
