UNSATURATED HCA, RCA, TTA

Product Code : Unsat HCA/RCA/TTA

Numerous GDS apparatus can be upgraded to perform unsaturated testing. Below is overview of some of our most advanced unsaturated apparatus.

Unsaturated Resonant Column Testing

 

The resonant column’s ability to measure soil stiffness at small strains with enough strain variability to measure the upper portion of the modulus degradation curve within soils, makes it an extremely attractive apparatus for testing unsaturated soils. A high air entry porous stone is fitted into the base pedestal, and pore air and water pressures are applied in the same way as a triaxial test. Note: A GDS resonant column apparatus can be upgraded to become an unsaturated RCA at any time.

 

 

Unsaturated Hollow Cylinder Testing (SDSWCC)

 

All GDS hollow cylinder apparatus can be upgraded to perform unsaturated hollow cylinder testing. A unique high air entry porous stone is fitted into the base pedestal, which consists of a number of circular bonds in the porous disks. The pore air and water pressures are applied in the same way as a triaxial test.

 

 

Unsaturated True Triaxial Testing (SDSWCC)

 

The GDS true triaxial apparatus can be upgraded to perform unsaturated tests. High air entry porous stones are fitted into the base actuator plate, and pore air and water pressures are applied in the same way they are in a triaxial test.
