ILI 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 condit ion when the failure stress (o, - 0,) was
found to be 132 kPa. What was the confining pressure o, for this test?
11.12 For the triaxial test in Problem I1.11:
(a) Estimate the direction of potential failure planes in the specimen
relative to the major principal stress plane.
(b) What are the normal stress o, and the shear stress T, on the failure
plane in (a)?
