The RCTS equipment allows for the acquisition of non-linear dynamic soil properties at low to intermediate strains. These dynamic characteristics include the determination of shear modulus and damping ratio curves relative to a given shear strain. The RCTS equipment is capable of performing two types of tests: the Resonant Column test and the Torsional Shear test.

The purpose of these parameters is to obtain the real, non-linear behavior of the soil for the dynamic analysis of geotechnical structures; the system is designed to handle confinement pressures of up to 1400 kPa, depending on the material type.

The application of these tests is for geotechnical structures such as leach pads, mine waste rock dumps, and tailings storage facilities, among others.

This equipment is the only one of its kind in Peru.

The Cyclic Triaxial Equipment allows for a wide variety of tests on specimens of 2.8” and 6.0” in diameter:

  • Dynamic soil properties, Young’s modulus, and damping ratio (ASTM D3999): Capacity to perform load-controlled or strain-controlled tests.
  • Cyclic undrained strength under load-controlled conditions (ASTM D5311): An appropriate test for evaluating soil liquefaction potential, which also allows for post-cyclic monotonic testing.
