Investigations on simulation of finite slope failure using image analysis and arbitrary Lagrangian-Eulerian
Investigations on simulation of finite slope failure using image analysis and arbitrary Lagrangian-Eulerian
Slope stability is one of the crucial geotechnical engineering problems due to its complexity in material heterogeneity and soil-soil interaction. The limit equilibrium method (LEM) and finite element method (FEM) are used to investigate the stability of slope by evaluating the factor of safety (FoS), however, these methods provide solutions considering small displacements. The slope failures like a landslide, debris flow, etc. are considered as large deformation problems (LDPs) and cannot be addressed accurately using the above-mentioned methods. In the last two decades, the image analysis technique is also proven to solve the problems like landslides. In the study, the failure of the finite slope is investigated by experimental and numerical simulations. The image analysis technique is used to visualize the failure envelope of the finite slope. An attempt is made to simulate the failure of finite slope using a large deformation finite element formulation i.e., arbitrary Lagrangian-Eulerian. The outcome of the image analysis and ALE study are compared to highlight the efficacy of the ALE method in simulating the failure of a finite slope.
