Resumo: | This thesis presents the development of a triaxial cell and a proposal for methodology for estimating horizontal tension edometric condition by conducting laboratory tests on samples unsaturated compacted soil in OMC. The development of triaxial cell permits the use of voltages or controlled deformation. Moreover, the machine allows independent application increments of axial and radial stresses, thereby facilitating implementation assay in any way triaxial stresses. The proposed methodology simplifies estimate lateral tension through comparison of axial stress-strain curves of the test edomÃtrico conventional triaxial and consolidation tests under different paths tensions with the constant relationship between the axial and radial increments. In this case, the value of K0 would be corresponding to the constant trajectory in which the triaxial test curve edomÃtrico overlaps the curve of the test in terms of stress and axial deformations. They were tests performed with different soil types and the results were- roughly consistent with estimates from correlations empirical, thus allowing validate the proposal presented in this research. also It was studied the change of horizontal stress during the collapse flood conditions in edomÃtricas. In these tests it was found that during the breakdown voltage can horizontal remain virtually constant or even decreasing. |

O desenvolvimento da cÃlula triaxial possibilita a aplicaÃÃo de tensÃes ou deformaÃÃes controladas.

A metodologia proposta simplifica a estimativa da tensÃo lateral atravÃs da comparaÃÃo das curvas tensÃo-deformaÃÃo axial entre o ensaio edomÃtrico convencional e ensaios de adensamento triaxiais sob diferentes caminhos de tensÃes com a relaÃÃo constante entre os incrementos axial e radial. Nesse caso, o valor de K0 seria o correspondente à trajetÃria constante na qual a curva do ensaio triaxial se sobrepÃe a curva do ensaio edomÃtrico em termos de tensÃes e deformaÃÃes axiais. Foram realizados ensaios com diferentes tipos de solo e os resultados mostraram-se aproximadamente concordantes com as estimativas realizadas a partir de correlaÃÃes empÃricas, permitindo dessa forma validar a proposta apresentada nessa pesquisa. TambÃm foi estudada a variaÃÃo da tensÃo horizontal durante o colapso por inundaÃÃo em condiÃÃes edomÃtricas.
