Two consolidated undrained (CU) tests were
conducted on two samples extracted from the same soil layer. The results are as follows: Specimen-1: confining stress = 16 psi, deviator stress at failure=29 psi, pore pressure at failure= 5 psi; Specimen-2: confining stress = 36 psi, deviator stress at failure=45 psi, pore pressure at failure= 17 psi. Calculate the effective shear strength parameters of this soil.

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...

Two triaxial compression tests are conducted on identical specimens of the same saturated clay. In the first test the soil is first consolidated to sc=350 kPa and u0=200 kPa and then sheared under drained conditions increasing the axial stress while keeping the chamber pressure constant. At failure s1= 560 kPa. In the second test, the specimen is consolidated to sc=600 kPa and u0=400 kPa, then it is sheared under undrained conditions increasing the axial stress while keeping the chamber pressure...
