            <documentation>An object describing the properties of a laboratory triaxial shear test procedure. In a triaxial shear test, stress is applied to a sample in a way which
                results in stresses along one axis being different from the stresses in
                perpendicular directions. In conventional triaxial tests, this involves subjecting a
                cylindrical soil sample to radial stresses (confining pressure) and controlled
                increases in axial stresses or axial displacements. Depending on the combination of
                loading and drainage condition, three main types of triaxial tests can be carried
                out: 1) Consolidated – Drained (CD), 2) Consolidated – Undrained (CU), 3)
                Unconsolidated - Undrained (UU). From the triaxial test results, it is possible to
                deduce the shear strength parameters, namely friction angle, cohesion, dilatancy
                angle and the other dependent parameters.</documentation>

                is useful in determining the compression index (slope of virgin curve), the

                (or maximum past pressure) of the soil. In addition, the data obtained can also be
