Abstract
Safety factors for soil slopes are calculated using a non-linear Mohr envelope. The often used linear Mohr-Coulomb envelope tends to overestimate the safety as the material parameters are usually determined at much higher stress levels, than those present at slope failure. Experimental data indicates that this leads to overestimation of the soil strength at low stress levels. The calculations are performed with the finite element method, and the plastic integration is carried out in principal stress space which simplifies the computations considerably.
