The tri-axial shear test is the most versatile of all the shear test testing methods for getting shear strength of soil i.e. Cohesion (C) and Angle of Internal Friction (Ø), though it is a bit complicated. This test can measure the total as well as effective stress parameters both. These two parameters are required for the design of slopes, calculation of bearing capacity of any strata, calculation of consolidation parameters and in many other analyses. This test can be conducted on any type of soil, drainage conditions can be controlled, pore water pressure measurements can be made accurately and volume changes can be measured. In this test, the failure plane is not forced, the stress distribution of the failure plane is fairly uniform and the specimen can fail on any weak plane or can simply bulge.
