For a soil, the effective angle of internal friction o was found to be 14° and the cohesion component e' was 46 kPa. The soil was tested in con- solidated drained triaxial condition when the failure stress (0, - 0,) was found to be 132 kPa. What was the confining pressure o, for this test?

For a soil, the effective angle of internal friction o was found to be 14°
and the cohesion component c' was 46 kPa. The soil was tested in con-
solidated drained triaxial condition when the failure stress (o, - 6,) was
found to be 132 kPa. What was the confining pressure o, for this test?
8.
Two similar specimens from the same site were tested under consoli-
dated undrained triaxial conditions with pore water pressure measure-
ments. The results are summarized here:

(a) Plot the Mohr's circles at failure in both the total stress and the
effective stress.
(b) Determine the strength parameters Q and e in the total stress and o
and c' in the effective stress.
9.
A cohesive soil was tested in a consolidated undrained triaxial test with
pore water pressure measurement and o = 24° and c = 26 kPa in the total
stress and o' = 27° and c' = 30 kPa are obtained. If the similar specimen
is tested under o, = 45 kPa:
(a) What will be the failure deviatoric stress?
(b) What will be the pore water pressure at failure?
10.
A consolidated undrained test was conducted on a clay speci-
men. The consolidation and chamber pressure was 50 kPa and the
failure o, was 86.2 kPa. If a similar specimen is first consolidated
under 50 kPa consolidation pressure and then tested in an uncon-
fined compression device, what will be the unconfined compression
strength q,?
11.
A consolidated clay had o' = 12° and e' = 30 kPa. When the same
specimen is tested in an unconfined compression device, the uncon-
fined compression strength q, = 90 kPa is obtained. How much pore
water pressure is generated in this unconfined compression specimen
at the failure?
