Resumo
Buckling failure occurs in the open pit
mines in the Quadrila´tero Ferrı´fero of the State of Minas
Gerais, Brazil. In this study, this failure mechanism is
evaluated through stress–strain analysis, using the finite
element software named Phase2. Many representative
hypothetical models of the slopes were created in order
to reproduce the conditions in open pit mines, like their
geometry and foliated joints with kinematic conditions
for buckling failure. Elastic and plastic simulations have
been done. Strength and deformability parameters, such
as discontinuity stiffness and cohesion, as well as the
in situ stress field, are analyzed in order to understand
their influence in the buckling failure mechanism in the
global open pit mine slopes excavated in phyllites. As
studies about this problem are extremely rare, the
present research brings important contributions to
establish the basic conditions for this kind of failure.
