Due to the shortcomings in the limit equilibrium method for modelling the actual failure mechanism and satisfy kinematics during slope failure, continuum-based methods were developed, such as finite element, finite difference, boundary element, and discrete element method. Amongst these methods, the finite element method is most widely used to solve slope stability problems assuming that the material is continuous. FEM gives more precise results as the analysis maintains force equilibrium, displacement compatibility at each node, constitutive equations to model linear elastic, nonlinear elastic or elastoplastic material behaviour, and the boundary conditions.
The examples of the stability analysis of large-volume structures like the Świerki open pit mine, the largest Polish lignite mine in Bełchatów and the reinforced railway embankment will be presented during the webinar. The emphasis will be put on the preparation of the numerical model and the analysis of the results. The influence of the model digitization method on the obtained results will also be discussed.
AGH University of Science & Technology
AGH is one of the largest Polish technical universities. At the Faculty of Mining and Geoengineering, numerical analyzes have been performed for many years at the request of external companies, both from the mining and construction industries. The main activities are focused on the slope stability, tunneling, foundations system.
