Question

In a CU triaxial test, a soil sample was consolidated at a cell pressure of 2kg/cm2 and a back pressure of 1kg/cm2 for 24 hours. On the next day, the cell pressure was increased to 3 kg/cm2. This resulted in the development of a pore pressure of 0.08 kg/cm2. The axial stress was then gradually increased to 4.5 kg/cm2, which resulted in a failure of the soil. The pore pressure recorded at failure was 0.5 kg/cm2. Determine Skempton’s pore pressure parameters A and B
