Using a deviator stress vs axial strain diagram, explain how the failure stress increases with cell pressure in a triaxial test. (i) Shear strength of a cohesive soil was determined in the laboratory using two samples. The first sample failed at a shear stress of 83 kPa and an effective normal stress of 90 kPa. The second sampled failed at 107 kPa and 135 kPa respectively. Determine the shear strength parameters (ii) of the soil.
