The design of landslide stabilization interventions requires a careful analysis and modelling of the deformation mechanisms occurring in the slope. In some cases, the classical two-dimensional (2D) stability calculation may lead to erroneous estimate of slope safety margin and therefore to incorrect design of stabilization works. Two different lanslides, both located in the Southern Italian Alps, have been back-analysed using 2D and three dimensional (3D) limit equilibrium methods, showing the importante of 3D effects in the estimate of safety factor necessary for a proper design of stabilization actions.

Abstract
The design of landslide stabilization interventions requires a careful analysis and modelling of the deformation mechanisms occurring in the slope. In some cases, the classical two-dimensional (2D) stability calculation may lead to erroneous estimate of slope safety margin and therefore to incorrect design of stabilization works. Two different lanslides, both located in the Southern Italian Alps, have been back-analysed using 2D and three dimensional (3D) limit equilibrium methods, showing the importante of 3D effects in the estimate of safety factor necessary for a proper design of stabilization actions.File in questo prodotto:
