Large Scale Polyaxial Rock Testing System

Large Scale Polyaxial Rock Testing System
The GCTS RPS-600 Polyaxial Rock Testing system can be used to study the intermediate principal stress effect on rock engineering behavior and describe adequately the strength of rock under a general system of Polyaxial compressive stresses. The RPS-600 is designed to apply 3 independent stresses (σ1, σ2 and σ3) onto a cubical test specimen. The stresses are achieved through hydraulic intensifiers applying pressure to solid platens in contact with the specimen. The system can be upgraded with pore pressure and temperature control.

Wide Variety of Standard Features:
  • Test cubical 300 mm x 300 mm by 600 mm tall rock specimens (12”x12”x24”)
  • Perform Polyaxial (true triaxial) tests
  • Independent control of σ1, σ2, σ3 (where σ1≠σ2≠σ3) or e1, e2, e3 or a combination of stress or strain control for each axis
  • Measures strains in all three orthogonal directions
  • Available ultrasonic sensors to measure P and S wave velocities under different stress states
  • Stainless steel construction
