Resumo: | |||||||||||||
The evaluation of the stability of the Robert Pit Mine
(Canada) is made through the field of
displacements of superficial and ground marks and possible
rupture mechanisms obtained
from the results of tension-deformation analysis by using
the program computational FLAC
(V. 3.30). Two constitutive models, the elastic perfectly
plastic model and elastic-plastic with
strain softening model, are used for the determination of
safety's factor and plastification area.
This work also defines the characteristics of cinematic
behavior of the rock slope under
gravitat ional condit ions.
A sensibility study is realized considering shear stress
and displacements in function of the
variation of the rock parameters and of the inclination of
the slope. The analysis of the factors
associated to the definition of the rupture mechanisms in
tension-deformation terms is also
done.
Finally, the comparisons are presented among safety's
factors calculated in function of the
results of the numerical analysis (FLAC) and safety's
factors calculated by limit equilibrium
methods in function of the potential rupture surfaces of
the computational model.
