Slope Failure of Noncohesive Media Modelled with the Combined Finite–Discrete Element Method

Abstract: Slope failure behaviour of noncohesive media with the consideration of gravity and ground excitations is examined using the two-dimensional combined finite-discrete element method (FDEM). The FDEM aims at solving large-scale transient dynamics and is particularly suitable for this problem. The method discretises an entity into a couple of individual discrete elements. Within each discrete element, the finite element method (FEM) formulation is embedded so that contact forces and deformation between and of thes… Show more

“…The safety factor of a slope will decrease if the slope force balance is disrupted [4]. This instability can occur due to external factors and internal factors that cause a decrease in the value of the safety factor [5]. There are 2 methods used to investigate slip surfaces, namely using experimental methods and numerical methods.…”

“…Different slope types also require corresponding finite element methods, which can be limited by the failure characteristics of highly discontinuous dumping. The discrete element method [33][34][35][36][37][38][39][40][41][42][43][44][45][46] differs from the finite element method, which due to its advantages in simulating the discontinuous characteristics of the discrete medium describe mechanical behaviors such as shear rolling or disconnection between the rock blocks (continuous body) and geological structural planes (discontinuous features). These are particularly suitable for studies of mass deformation or the failure process.…”
