v6.03.006 SSNP006 — Analysis of the stability of a homogeneous slope using the Bishop method

Summary:

This test case analyzes the stability of a homogeneous slope in embankment. We calculate the factor Slope safety using the simplified Bishop method based on limit theory balance using macro command CALC_STAB_PENTE.

The test case comes from the validation cases of the American geotechnical software Plaxis2D developed by Geostudio.

Comparing the result with the reference value, the result of CALC_STAB_PENTE has an error of 0.84% probably caused by the difference in the shape of The basis of slices and the discretization of the space of geometric variables of the fracture surface.

**The consistency between results CALC_STAB_PENTE, Plaxis2D and the literature allows scientifically validate the Bishop method and the associated optimization algorithm implemented in CALC_STAB_PENTE. **
