Answer #1

Normally consolidated clay is that type of clay in which the present stress which it is experiencing greater than the stress the soil has been experiencing means present stress is the max stress it has been acted upon.

Over consolidated clay is that type of clay which has experienced a stress greater than the present stress it is acted upon that means the soil has been acted upon by stress greater than the present stess in the past..

Over consolidation ratio (OCR) is ratio of pre consolidated stress / present stress.

For NC clay OCR < 1

For OC clay OCR > 1

A normally consolidated clay is consolidated under a stress of 100 kPa, then sheared undrained in a triaxial compression. The principal stress difference (deviatoric stress) at failure is 250 kPa and the induced pore pressure is 60 kPa. Calculate the minor principal stress at failure in term of effective stress (s3')f? (Unit: kPa).

Assume a rigid strip footing is constructed on a normally consolidated clay layer under a uniformly distributed vertical load. The depth of footing is zero and the water table is a few metres below the surface ground. The average shear strength parameters of the clay layer are: • At the beginning of loading: fu = 0, cu = 50 kPa • Long time after loading:, f’ = 25° and c’ = 0 kPa. Will the bearing capacity of this footing...

A sample of normally consolidated clay was subjected to a CU triaxial compression test that was carried out until the specimen failed at a deviator stress of 50 kN/m2. The pore water pressure at failure was recorded to be 18 kN/m2, and a confining pressure of 48 kN/m2 was used in the test. The cohesion of the clay was 20 kN/m2 at the failure. draw both the effective stress strength envelope and total stress strength envelope. identify the effective internal...
