Consolidated undrained triaxial tests are performed on two identical specimens of saturated, remolded clay with pore pressure measurements. The observations are recorded in the table below: Consolidation Pressure (K Pa) 250 350 Cell pressure at Deviator Stress Pore Pressure at failure (K Pa) 250 350 Test No at Failure (K Pa) failure (K Pa) 180 250 105 151 1 2 Determine the values of the shear strength parameters, cohesion ad friction, for the clay both in terms of total and effective stresses. If in consolidation undrained test, an identical specimen is first consolidated under a cell pressure of 400 K Pa, what would be the deviator stress at failure?

Question
Transcribed Image Text:Consolidated undrained triaxial tests are performed on two identical specimens of saturated,
remolded clay with pore pressure measurements. The observations are recorded in the table below:
Consolidation
Pressure (K Pa)
Cell pressure at Deviator Stress Pore Pressure at
failure (K Pa)
250
350
Test No
at Failure (K Pa) failure (K Pa)
105
151

250
Determine the values of the shear strength parameters, cohesion ad friction, for the clay both in
terms of total and effective stresses.
If in consolidation undrained test, an identical specimen is first consolidated under a cell pressure
of 400 K Pa, what would be the deviator stress at failure?
