Choose the incorrect statement about the Triaxial Compressio

Choose the incorrect statement about the Triaxial Compression Test.

The shear resistance (inherent stability) of soil is represented by the Mohr-Coulomb failure criterion

B.

The goal of the Trial Compression Test is to determine the shear strength of a soil under the lateral pressure.

The Mohr-Coulomb failure criterion is based on the assumption that cohesion and internal friction may be combined in a single component of shearing stress.

The deviator stress is one of principal stresses along the vertical axis.

Solution

Option A, B and D are right. But C is incorrect because there is no relation of cohesion and iternal friction is this theory.
