Concept explainers

Test for Determination of Shear Strength

The term shear strength is often associated with the soil. Shear strength is defined as the resistance to the deformation of soil particles due to the continuous action of shear stress. In short, shear strength is the maximum shear stress that a soil can sustain.

Question

In a consolidated-drained triaxial test on a clay, the specimen failed at a deviator stress of
124 kN/m?. If the effective stress friction angle is known to be 31°, what was the effective
confining pressure at failure?
