The results of two consolidated undrained triaxial test on two soil specimens are shown in the table below. Specimen 1 2 Cell pressure, 03 (kPa) 150 300 Deviator stress, (od) (kPa) 189 295 Pore water pressure at failure, u (kPa) 80 116 i. Plot the Mohr's circles at failure for two specimens in terms of effective stress. (13 marks) ii. Determine the shear strength parameters c' and ' from the effective stress failure envelope. (4 marks) c' = 45 kPa = 19 b) Compare the term drained and undrained soil with reference to the state of soil or loading conditions. (8 marks)
