Miniature triaxial apparatusIt is an instrument used to test the mechanical properties of materials such as soil. Its compact structure and small sample size can be combined with CT scanning technology to achieve synchronous research on the microstructure and mechanical behavior of materials.

　　Miniature triaxial apparatusThe working principle of is based on the principle of traditional triaxial testing equipment, which uses a confining pressure generator to discharge gas and fill the confining pressure chamber where the sample is located with liquid, thereby obtaining the confining pressure. Under a given confining pressure, the axial loading system where the control head is located performs axial shear on the specimen, and records the axial stress corresponding to the axial displacement during this process, thereby obtaining the stress-strain curve. Through these data, the shear strength, liquefaction characteristics, and dynamic stress-strain characteristics of the soil can be calculated.
Features:

Compact structure, small size, and light weight: The main body of the miniature three-axis instrument has a compact structure, small size, and light weight, which makes it very easy to carry and use, whether in the laboratory or on-site testing, it is very convenient.

Miniaturization of soil samples: The instrument adopts a smaller pressure chamber and micro soil samples, which enables the CT scanner to clearly scan the microscopic imaging of soil samples before and after the experiment, providing researchers with more detailed information on the microstructure of soil samples.

Non destructive testing: During CT scanning, the miniature triaxial apparatus can maintain triaxial pressure, which means that the soil sample can be scanned without unloading, avoiding the possible effects of unloading, ensuring the in-situ and continuity of experimental data, and improving the reliability and accuracy of the experiment.

Convenience of operation: The instrument is usually equipped with a dot matrix color touch screen and an automatic data recording and processing system. Users can control the experiment through the touch screen or PC, and collect, store, and process the experimental data, greatly improving the convenience and efficiency of operation.
