Please answer 12.20 12.20 Undisturbed samples from a normally consolidated clay layer were collectedduring a field exploration program. Drained triaxial tests showed that the effectivefriction angle d' = 28°. The unconfined compressive strength, q, of a similarspecimen was found to be 148 kN/m?. Determine the pore pressure at failure forthe unconfined compression test.

Since limited data is given We have to use skempton pore pressure parameters

A normally consolidated clay sample is subject to a triaxial test where pore water pressure measurements are made. A consolidated–undrained type of test is performed. The sample fails (shears) when the total all-around confining pressure is 45 kPa and the total axial pressure is 97 kPa. At failure, the recorded pore water pressure is 20 kPa. Determine the angle of internal friction fCD for the effective stress strength envelope and also the value for fcu.
