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-undrained triaxial test was conducted on a dense sand with a confining pressure of 138 kN/m². Results showed that ϕ′=24 deg and ϕ=31 deg. Determine the deviator stress and the pore water pressure at failure.
