Answer #1

TRUE. In triaxial test there is a valve which can be opened or closed durign the shear stage. In UU ( unconsolidated undrained) test and CU ( consolidated undrained ) test the valve is kept closed in the shear stage. So the pore pressure can be measured. The cylindrical specimen used in the triaxial test has length two times its dia. The change in volume and length of specimen is noted.

A drained triaxial test is conducted on a soil with friction angle of 25° and zero cohesion, using a chamber pressure sc=300 kPa and a back pressure (this is the term used to denote the initial value of the pore pressure, u0) equal to 200 kPa. The shear stage of the test is performed DRAINED by increasing the axial stress s1, while concurrently decreasing the chamber pressure s3 so that their sum remains constant (s1+s3 = constant). Draw the effective...

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...
