Triaxial Automated System (GDSVIS Load Frame System)

The GDS Virtual Infinite Stiffness loading system (GDSVIS) is the premier load frame in the GDS range with load capacity 100kN, and maximum pressure of 2MPa (simulates environments up to ~80-100m deep). It tests both soil and rocks. This equipment is fully automated geotechnical triaxial testing equipment. It allows for a large range of geotechnical testing and we use it to study the solution process of rock samples containing gypsum with monitoring what is dissolved in the outflow. Some of the tests that can be performed include the following: • Consolidated Drained (CD) Triaxial • Consolidated Undrained (CU) Triaxial • Unconsolidation Undrained (UU) Triaxial • Consolidation (Triaxial) • Constant Rate of Loading (CRL) Consolidation • Constant Rate of Strain (CRS) Consolidation • Slow Cyclic Testing, K0 (K-Zero) • Multi-Stage Testing • Quasi-Static (low speed/creep) Tests • Stress Paths Triaxial testing equipment is a fundamental piece of equipment to any Geomechanics or Geotechnical laboratory or research center. This new equipment, will complement the existing “high pressure core flooding machine”, (which allows for rock testing at reservoir pressures and temperatures), since it will cover the shallow subsurface conditions (up to 2MPa) and will allow for several types of other geotechnical testing of both rock and soil materials. It is fully automated and can be configured to the user’s specifications. Automated control allows tests to proceed constantly and increase throughput of tests. The user can choose the load frame, pressure controllers, triaxial cell or just parts to integrate into existing equipment to build their ideal set-up. This means that components can be added (purchased) or removed to change set-ups during the lifetime of the equipment, and allow running different types of tests. Finally the system is compatible with other manufacturer’s products, which means that existing components they can incorporate them with GDS equipment to create a system, saving expense.
