3D numerical simulation of slope-flexible system interaction using a mixed FEM-SPH model

Flexible membranes are light structures anchored to the ground that protect infrastructures or dwellings from rock soil sliding. One alternative design these is by using numerical simulations. However, very few models were found until date and most of them in 2D do not include all their components. This paper presents development a model combining Finite Element Modelling (FEM) with Smooth Particle Hydrodynamics (SPH) formulation. Both cylindrical spherical failure slope simulated. reference geometry was designed total 21 slip circles calculated considering different parameters, phreatic level position drainage solutions. Four case studies extracted scenarios simulated dimensions components system. As validation model, an experimental test imitates detachment its retention steel membrane successfully reproduced.
