Temperature-Controlled Triaxial System HC-TBTS

Product Introduction

This is a highly integrated and intelligent temperature-controlled triaxial testing system, specially designed for investigating the mechanical behavior of geotechnical materials under thermo-mechanical coupled conditions. By integrating a high-precision temperature control module with a triaxial static loading mechanism, the system can accurately simulate the variable temperature conditions and complex stress states that materials undergo in practical engineering. It is widely used in scientific research and engineering testing in civil engineering, water conservancy and hydropower, transportation and other fields.

The system features low cost, multi-functionality and high integration. It supports static loading under both stress-controlled and strain-controlled modes, and is fully compatible with conventional triaxial test methods, including B-value check, back-pressure saturation, UU (unconsolidated undrained), CU (consolidated undrained), CD (consolidated drained) tests, etc. It can also perform loading-unloading cycles of confining pressure and axial pressure, as well as user-defined static test procedures.

The system is equipped with an advanced full-surface deformation digital image measurement system. Adopting non-contact measurement technology, it can accurately capture the full-field strain of unsaturated soil specimens during testing, as well as the evolution of crack development.
