is desired to obtain information about the in-situ strength properties cohesion and angle of friction for a saturated soil and also the pre-consolidation pressure. Direct shear tests under consolidated undrained conditions are performed on three identical samples of clay. For sample one, the applied normal pressure is 36 kPa and the sample fails when the sheer stress is 21.6 kPa, for sample two, the applied normal stress is 72 kPa and the sample shear stress is 24 kPa, for sample three, the applied normal pressure is 120 kPa and the sample shears at 38.4 kPa. Compute the value of cohesion in kPa. Show

Test for Determination of Shear Strength

The term shear strength is often associated with the soil. Shear strength is defined as the resistance to the deformation of soil particles due to the continuous action of shear stress. In short, shear strength is the maximum shear stress that a soil can sustain.
