Resumo: | |||||||||||||
In this present research, it was done an interpretation of the reinforcement
work s behavior in a containment dike/dam for mining waste built on soft soils. It
was defined the geotechnical profile and the heightening steps to be performed
using the finite element method in the Plaxis 2D software. To define the parameters,
the field and laboratory tests were interpreted, and in the laboratory tests in which
the curvatures were known, it was possible to apply parameters with the simulation
of tests in an extension of Plaxis (Soil test). In the case of sandy silt soils and
embankments materials, as was done with the Hardening Soil Model. For the clay
layers, five different scenarios were simulated with the models: Soft Soil,
Hardening Soil and Mohr Coulomb with effective strength parameters and
Hardening Soil and Mohr Coulomb with undrained strength parameters. The
displacement results were compared with each other and with field monitoring data.
For the stability analysis the five scenarios were analyzed among themselves and
with the results of a conventional analysis with limit equilibrium in terms of total
strength. Also the application of the Displaced Volumes Method as a way of
verifying its suitability to in situ monitoring of the stability of the work at each
constructive stage.
