Assume a consolidated drained triaxial compression test is to be performed on a medium stiff clay sample extracted from 100 ft below surface and consolidated to its in-situ effective stress state. Assume the GWT is 20 ft below ground surface level. Assume the moist unit weight above the GWT is 100 pc and the saturated unit weight below the GWT is 130 pc. Assume the Ko for the clay is 0.7. Assume that the effective cohesion is zero and the angle of internal friction is 35 degrees. Estimate the following: (a) deviator stress at failure: (b) shear strength (on the failure plane). (c) angle of failure of the shear plane

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.
