Landslides are characterized by large deformations in the soil mass. This study used the material point method (MPM), a particle-based method that takes advantage of a double Lagrangian-Eulerian discretization. This approach provides a robust framework that enables the numerical simulation of large strains, without mesh entanglement issues that are common with the Finite Element Method. The numerical model proposed here assumes simplifications of the geotechnical, morphological and structural buildings conditions on the site. Nevertheless, the final numerical deformed configuration described the geometric features observed in the field successfully. The result allows applications such as the design of barriers, risk assessment or determination of a minimum safe distance for a building from a slope susceptible to landslides. 2015 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49643211019 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.194 Vol.82 |
