MOS Grondmechanica has 13 triaxial configurations at its disposal. With the triaxial test the behavior of a soil layer is determined; how does the soil deform under loading and unloading? There are several types of triaxial tests; the most well-known are the consolidated drained and undrained tests, better known as the CD and the CU test. The software for conducting and devising the tests has been developed in-house.
The test is traditionally conducted at three different stress levels.This is done to determine a phi and c value. When the test is conducted on the same sample with three steps, this is referred to as multi-stage and on three homogeneous samples it is called a single-stage. From the comparison of the strength and deformation of the soil samples with these different loads the behavior of the soil can be determined in regards to load changes(loading and unloading). One step tests that are added to a test collection also occur more frequently.
