Ponts et charpentes Résumé : In the fields of experimental geomechanics, the classical or typical triaxial apparatus is one of the most widely used testing equipments for the estimation of the material parameters. The testing procedure is rather simple and the basic principles of the apparatus are easy to understand. In situ stress states can be (re-) applied to the specimen in a rather simple and effective way. The stresses and/or strains, imposed to the specimen, are also precisely controlled and monitored. However, the experimentalist should always keep in mind the limitations of the apparatus, imposed by its design. In this paper, a critical discussion on the limitations of the classical or typical triaxial apparatus is presented. Modifications of the initial design are suggested in order to overcome such limitations and improve measuring techniques.
