Triaxial Test Systems
The Triaxial Test System is a high-performance, laboratory-grade soil testing machine designed for advanced geotechnical analysis. Engineered to deliver precise measurements under controlled pressure conditions, this system is essential for determining shear strength, stress-strain behavior, and permeability of soil and rock samples under different drainage conditions.
Featuring a servo-controlled load frame, a closed-loop digital control system, and a modular triaxial cell, it supports test configurations including Consolidated Undrained (CU), Consolidated Drained (CD), and Unconsolidated Undrained (UU) methods. The system also accommodates stress path testing and cyclic loading, making it highly suitable for academic research, construction, and civil engineering applications.
Key Features of the Triaxial Test System
- Servo-controlled load frame for precise axial loading
The system uses a highly stable and responsive servo mechanism to apply and control axial loads with fine accuracy, ensuring reliable results across all types of triaxial tests. - Fully automatic data acquisition and control system
All measurements — including force, displacement, pore pressure, and volume change — are captured digitally in real time, minimizing manual intervention and human error. - Supports multiple triaxial test configurations
Compatible with Consolidated Undrained (CU), Consolidated Drained (CD), Unconsolidated Undrained (UU), stress path, and cyclic testing protocols — all programmable via software. - High-precision pressure control for confining and back pressure
Enables independent regulation of cell pressure and back pressure, essential for accurate pore pressure response and shear strength determination. - Durable and corrosion-resistant triaxial cells
The transparent, high-strength triaxial cells are built from corrosion-resistant materials for long life and safe operation under high pressure. - Automatic measurement of volume change and pore pressure
Equipped with sensors to continuously track volume changes and pore water pressure during the test — critical for analyzing saturated and unsaturated soil behavior. - Integrated computerized control software
User-friendly PC software offers preloaded test templates, real-time graphing, data logging, and result analysis — making complex tests easier and faster to perform. - Optional accessories for advanced soil mechanics research
Can be configured with local strain measurement devices, cyclic loading modules, or temperature-controlled triaxial cells for specialized geotechnical applications. - Wide specimen compatibility
Accommodates soil samples with diameters ranging from 38 mm to 100 mm, suitable for standard and large-scale testing in labs and field investigations. - Engineered for repeatability and long-term lab use
Built with anti-corrosive, wear-resistant components to withstand frequent testing in demanding soil and rock laboratories. - Compliant with global geotechnical standards
Meets or exceeds the requirements of ASTM D2850, D4767, BS1377, and ISO 17892, ensuring the data is valid for international engineering projects.
