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.

Question

Two identical specimens, 4 cm in diameter and 8 cm high, of partly saturated compacted soil are
test in a triaxial cell. The first specimen fails at an additional axial load (i.e., deviator load) of 720
N under a cell pressure of 100 KN/m2 The second specimen failed at an additional axial load of
915 N under a cell pressure of 200 KN/m². The increase in volume of the first specimen at failure
is 1.4 ml and it shorten by 0.6 cm, at failure. The increase in volume of second specimen at failure
is 1.8 ml, and it shortens by 0.8 cm at failure. Determine the value of apparent cohesion and the
angle of shearing resistance. 7

Two drained triaxial compression tests are carried out on "identical" specimens of clean sand. In each test, a fully saturated specimen is consolidated to a confining stress and then failed by increasing the vertical stress. The test results are summarized in the following table.
