Validity Criteria of Oedometric and Triaxial Test Results
Abstract Oedometric and triaxial tests are very much used in soil mechanics. However, in spite of their frequency in the world, these tests present some limitations related to remolding due to sampling process and to implemented experimental procedures. These limitations contribute to decreasing the resistance and deformability mechanical properties of soils, which condition their limit and critical states behavior. This paper proposes four validity criteria of oedometric and triaxial test results (compressibility criterion based on the oedometric test results; consolidation, resistance and rigidity criteria based on the triaxial test results) to appreciate the disturbance of test specimens. Impact of the sample disturbance on the yield envelope of clayey soils according to these validity criteria is then analyzed.
