Shear strength reduction analysis and its usage in slope stability with unconfined seepage
Shear strength reduction analysis and its usage in slope stability with unconfined seepage
In this contribution, we introduce the shear strength reduction analysis built on an optimization definition and Davis approxi-mations of the non-associated Mohr-Coulomb plastic flow rule. This optimization framework has many common features with limit analysis. For example, it is possible to analyse duality between static and kinematic principles or use more advanced numerical methods. A solution concept based on a regularization method, standard finite elements, continuation Newton method and mesh adaptivity is used. The suggested shear strength reduction analysis is used for a case study of a heterogene-ous embankment dam. For the comparison of results, the Plaxis code is considered.
