High Confining Pressure Triaxial Testing System

System Description

This system can apply a wide range of axial loads, confining pressures and back pressures. Its full-surface deformation image measurement system captures both global and local deformations of soil specimens. It is widely used in deep-sea resource development, nuclear waste storage and other fields.

It supports B-test, back-pressure saturation, UU, CU, CD, confining pressure loading-unloading cycles, axial pressure loading-unloading cycles, K₀ tests, stress path tests, creep tests, as well as customized user-defined tests.

System Features

Equipped with an image measurement function, with a strain measurement accuracy of 10⁻⁴.
