Resumen

Soil nailing is a world-wide frequently used technique for temporary and permanent slope stabilization applications and excavations with vertical or nearly vertical cuts. A case study is analyzed applying both limit equilibrium (LEM) and finite element method (FEM), including comparison with internationally used codes and standards. In this paper different approaches are used in FEM for simulation of soil nails by different structural type in order to study its influence on results, e.g. (a) only axial stiffness in nails is taken into account or (b) bending and shear stiffness beside the axial stiffness.
