摘要:
This research presents a novel approach to addressing plane strain stability problems in rock masses, obeying the generalized Hoek-Brown failure criterion. The methodology integrates upper bound (UB) finite element limit analysis (FELA) with power cone programming (PCP) techniques. To achieve significantly enhanced UB results, quadratic velocity elements are employed for the discretization of the kinematic theorem. Within the UB formulation, the generalized Hoek-Brown (GHB) yield criterion is represented through a series of linear constraints a...
