NC clay, chamber confing pressure is 345 kn/m^2, deviator stress at failure is 325bkn/m^2.
a.) sketch mohr circle with radius and center coordinates
b.) a drained triaxial test of the same sand was conducted on the same sand. the specimen failed with deviator stress 250 kn/m^2. find chamber confining pressure

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...

QUESTION (1): A clay till has a cohesion of 10 kPa and a friction angle of 30 degrees. The vertical stress in the unit is 90 kPa and horizontal stress is 50 kPa. The porewater pressure in the clay till is 40 kPa. Using effective stress, sketch the Mohr circle and failure envelope for the clay till. Is failure expected? (Question Continue from question 1) Assume that the clay till has been subjected to displacement due to shearing in the...
