1. The structure of the testing machine adopts four columns. In order to improve functionality, various three-axis tests can be completed under vertical servo actuators. The pressure chamber is pushed on the guide rail to load and unload samples in the three-axis pressure chamber.

2. Axial loading system: Includes host, force sensor, axial deformation sensor, radial and confining pressure deformation sensor, oil cylinder (actuator), displacement sensor, measurement and control device and software, positive sine wave loading, and servo oil source control.

3. Lateral (confining) loading system: Includes three-axis pressure chamber, servo pressurization system, and booster.

4. Microcomputer system: Specialized software for professional testing and analysis.

Uniaxial Compression Test:

• Program functions: Constant stress, constant strain deformation, constant compression rebound creep, variable speed test, unidirectional cycling, and uniaxial rheological test.
• Triaxial compressive strength of rock concrete, full process test, and cyclic test.
• Optional fixtures for rock concrete splitting (indirect tensile, flexural).
• Parameters: Uniaxial rheological, relaxation, residual strength, elastic modulus, and Poisson's ratio.

Triaxial Compression Test:

• Axial compression under constant confining pressure, multi-stage confining pressure waveform stress-strain cyclic test.
• Rock concrete triaxial compression, triaxial cycling, triaxial rheology, and triaxial full process.
• Characteristic parameters: Triaxial residual strength, elastic modulus, Poisson's ratio, etc.
• Curve storage: Software control of stress-strain waveform curves and storage of peak values with data graphics.
• Reverse Osmosis and Automatic Seepage System selection.
