- Abstract
The critical state theory has been widely applied in geotechnics, and understanding the mechanical and geotechnical properties of particulate materials is one of the major challenges nowadays. In the mining industry, this is a concern regarding tailings storage facilities, that experience transitions from drained to undrained conditions, which might trigger phenomena like static liquefaction compromising the stability of the impoundment; the seeking of constitutive models that allow doing the behavior analysis of tailings and evaluate the global stability of TSF must lead to use models based on the critical state theory. The present research explores experimentally the assessment of the critical state locus in reconstituted samples of iron tailings, through drained (CID) and undrained (CIU) triaxial tests to evaluate the effectiveness of modeling the behavior of this material using NorSand a critical state model. Once the CSL was defined, several simulations of the tests were done using visual basic coding and comparing the experimental data against the synthetic tests. The testing procedure as well as the results and calibration of the model are discussed.
