Triaxial Cells

Product Code : Cells

GDS produce an extensive range of triaxial cells in order to satisfy the complex range of tests required by today’s modern geotechnical laboratories.

Traditional passive triaxial cells (known as passive due to the fact that they are used with an external actuator such as a load frame to apply axial loads), large diameter triaxial cells (up to 500mm sample diameter), active triaxial cells (based on Bishops and Wesley’s original hydraulic stress path apparatus and include an actuator ‘built in’), as well as cells specifically designed for dynamic triaxial testing with low friction bearings and seals are available from GDS. In addition, there are a number of features such as balanced ram triaxial cells, access ports and access rings for internal transducers that are offered.

Tests supported by the Triaxial Cells, static triaxial testing equipment for soil testing :-

Constant Head Permeability

The constant head test simply maintains a constant differential in pressure between the top and the base of the specimen (top pressure is always set higher than the base pressure). The flow is then measured on the top controller and the base controller.  Please note: Some apparatus may require additional components or software modules to perform certain tests.

Constant Rate of Flow Permeability

The constant rate of flow test simply maintains a constant base pressure whilst applying a constant flow through the top of the specimen. A maximum hydraulic gradient can be set which will pause the rate of flow if the pressure differential between the top and the base of the sample gets too large.  Please note: Some apparatus may require additional components or software modules to perform certain tests.
