Abstract：The basic structure and the function of MTS digital program servo-controlling uniaxial mechanics test machine are introduced. Based on the uniaxial MTS test machine，the development idea of the measuring system for mechanics properties of rock under the convectional triaxial stress state and pore content of rock is elaborated. The complete-process deformation property of RCC under the convectional triaxial stress state and the porosity change of fine sandstone with confining pressure are tested using the developed test equipment. The results show that the developed equipment can meet the demand of rock mechanics testing study for scientific research and design of rock engineering.
