(a) Briefly explain Mohr-Coulomb theory and show how we can determine the shear strength parameters of soil by plotting the shear stress versus normal stress. [3 marks] The following results were obtained from a consolidated undrained Triaxial (CU) test with pore water pressure measurement on three samples of a fully saturated clay. Determine the total (undrained) stress and effective (drained) stress parameters. [12 marks] Sample Cell pressure (kN/m2) Deviator stress at failure (kN/m2) Pore pressure at failure (kN/m2) A 300...
