Limit Equilibrium or Strength Deformation Analysis on Residual Strength

[geot88]

I will be analyzing the slope of an embankment over soft clays. It has been probably 2 years since the embankment was built and it shows many cracks -probably because it has slid a little bit- and I believe the clay under the embankment may have reached its residual strength. Can I perform a limit equilibrium analysis? What considerations should I take?
Thanks!

Yes you can perform a limit equilibruim analysis. Method will be the same as you would use on any slope. Select appropriate shear strengths for all of your materials, which could be residual, peak or something in between, and run the analysis.
