Análise numérica do comportamento tensão-deformação dos solos da formação barreiras utilizando cam-clay modificado

Abstract

The objective of this work is the quantitative analysis of the stress-strain behavior of the soils of the Barreiras Formation based on the use of existing experimental data in the Experimental Field of Geotechnics at the Federal University of Alagoas (CEG/UFAL). For this, simulations were performed using the Plaxis 2D Software, specifically using the Modified Cam-Clay constitutive model. The objective of the study is to evaluate the feasibility of the model in the study of stress-strain behavior when compared to the conventional Mohr-Coulomb model, in addition to incorporating it into the knowledge of students at the undergrad level. The result obtained by the study was the non-feasibility of using the Modified Cam-Clay model with regard to the prediction of soil deformations in the Barreiras Formation, since the results obtained for the four simulations carried out were very different from those obtained with the model of Mohr-Coulomb, which already has a consolidated application.
