A normally consolidated clay sample is subjected to a tri-axial test where pore water measurements are made. A consolidated-undrained type of test is performed. The sample fails when the total all-around confining pressure reaches 104 kPa and the total axial pressure is 308 kPa. During the drained condition, the drained friciton angle is 53.56°. Determine the pore water pressure (in kPa) measured during the test.

A clay sample was consolidated in a triaxial cell under a backpressure of 50 kPa and cell pressure of 150 kPa. The drainage valve was then closed and the cell pressure was increased to 200 kPa when the pore pressure increased to 98 kPa. What is Skempton’s B-parameter? The above sample was then subjected to a vertical deviator stress, which was increased from zero under undrained conditions. The sample failed when the pore water pressure was 160 kPa and the deviator stress was 70 kPa. What is Skempton’s A-parameter at failure? Assuming the clay is normally consolidated, find the friction angle in terms of effective stresses.

A clay sample with all-round pressure of 200 kPa has been solidified to a specific volume of 1.9. The second clay sample is solidified from the same soil to an all-round pressure of 600 kPa and then allowed to expand to a pressure of 50 kPa, which in this case has a specific volume of 1.9. Both specimens are then subjected to a drained compression three-axis test. For 3, Landa is 0.1 and M is 0.9. Obtain the effective stress values, specific volume, and volumetric strain of these two gamma-sample clays when they reach the critical state line.
