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

A consolidated-drained triaxial test on a sand yields the results:
All-around confining pressure = σ₃ = 30 lb/in²
Added axial stress at failure = Δσ = 96 lb/in²
Determine the shear stress parameters (i.e., Φ' and c')
