Undisturbed samples from a normally consolidated clay layer were collected during a field exploration program. Drained triaxial tests showed that the effective friction angle ϕ' = 28°. The unconfined compressive strength, qu, of a similar specimen was found to be 148 k N/m2. Determine the pore pressure at failure for the unconfined compression test.
