Soil triaxial resonant column tester

The Soil Triaxial Resonance Column Tester is an advanced geotechnical instrument used to measure the dynamic mechanical properties of soil in a small strain range (usually 10 ⁻⁶~10 ⁻ ³). It combines the advantages of traditional triaxial testing and resonance column technology, and can simultaneously study dynamic parameters such as shear modulus (G) and damping ratio (λ), as well as static deformation characteristics of soil. Here is its detailed description:

Major function

Dynamic characteristic testing: Determine the shear modulus (G) and damping ratio (λ) of soil under small strain using resonance frequency method.

Static characteristic testing: supports conventional triaxial tests (such as UU, CU, CD) to obtain parameters such as shear strength (c, φ) and deformation modulus.

Wide coverage of strain range: seamless transition from small strain (elastic zone) to large strain (nonlinear failure zone).

-Multi field coupling (optional): can integrate temperature control and seepage systems to simulate complex environments (such as frozen soil and saturated soil).
