abstractsIn the paper, various methods of measuring a sample strains in a triaxial test are analysed. Accurate determination of the deformation of a specimen in a triaxial compression test is of great importance for correct evaluation of soil strain-stress characteristics, particularly in the pre-failure stress state in the range of small strains. In the paper, three different methods of measuring axial strains are analysed and discussed. Two consider the measurement of relative movement between top cap and base pedestal of the triaxial cell, the third being based on the direct measurement of local axial deformation of the sample tested. The measurement of radial strains is also discussed in respect of the corrections introduced for the specimen's bulging. To analyse various methods of strains measurements tests on diverse materials such as sand, steel and rubber were carried out, enabling the evaluation of the efficiency and accuracy of the measurement methods applied.
