Two soil specimens, A and B,
were subjected to
Consolidated-Undrained
triaxial test. Specimen A,
which was pre-consolidated at
a cell pressure of 50 kPa,
failed at a deviator stress (q)
of 103 kPa and excess
porewater pressure of 37 kPa.
Specimen B, which was pre-
consolidated at a cell pressure
of 200 kPa, failed at a deviator
stress (q) of 185 kPa and an
excess porewater pressure of
124 kPa. Determine the
strength parameters based on
total stresses (c and phi). Write
your answer below.
