Abstract Based on the testing principle of the Mogi Type rock true triaxial apparatus，the key technology that the measurement of volumetric deformation of rock，the end friction effect，the loading gap and the capture of the complete stress-strain curves are introduced in terms of the principle for designing. The test system realizes the measurement of the stress-strain curves for hard rocks under the condition of true triaxial compression with high rigidity，large loading capacity as well as fast response. The friction coefficient under different anti-friction conditions and the influence of end friction effect on rock deformation were studied. It is shown that the mixture of stearic acid and Vaseline has good anti-friction effect and is thus recommended to be used in the true triaxial experiments. Meanwhile，the end friction often results in the uneven distribution of rock deformation and the deformation modulus and strength of rock to increase.

Key words： rock mechanics true triaxial testing end friction effect hard rocks complete stress-strain
