Analysis of slope stability based on finite deformation theory
This paper deduced the strain distribution of the slope by using the finite deformation theory based on the regulation of slope displace and deformation, and it is found that the strain field obtained from the Cauchy strain hypothesis is obviously inaccurate by comparing with that from the finite deformation theory. Results show that the displacement and deformation of slope are large deformation cases, the distribution of strain of slope can be gotten exactly by using the finite deformation theory. Meanwhile, the virtual strain is introduced and higher order deformation ignored for the Cauchy strain hypothesis, thus it is often misleading in the works execution and slope engineering evaluation.
