About Computerized Triaxial Testing System
Determining the mechanical properties of soils is a very important step to design foundations,embankments and other soil structures. Building constructions, excavations, tunneling and similar applications have several effects on the subsoil structures and these effects are successfully simulated with Triaxial Tests where the stress-strain relation of undisturbed soil specimen are investigated by subjecting the soil sample to different stress levels and drainage conditions. The Labtest Triaxial Test System provides automated triaxial compression tests on cylindrical undisturbed and remolded soil samples. Unconsolidated undrained (UU), consolidated drained (CD) and consolidated undrained (CU) compression tests can be automatically run, controlled and reported using this apparatus.
Unconsolidated Undrained (UU) Test:
- For the UU test, the specimens (assumed to be saturated prior to test) are subjected to a confining fluid pressure in a triaxial chamber.
- Once the specimen is inside the triaxial cell, the cell pressure is increased to predetermined value by rotating the knob, and the specimen is brought to failure by increasing the vertical stress by applying a constant rate of axial strain.
- Saturation and consolidation are not permitted to keep the original structure and water content of sample untouched.
- Pore pressures are not measured during this test and therefore the results can only be interpreted in terms of total stress.
- These tests are generally carried out on three specimens of the same sample subjected to different confining stresses.
