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

A consolidated undrained triaxial test was conducted on a normally consolidated clay.
Following are the results of the test:
• Cell or Chamber pressure = 200+X kN/m?
• Deviator stress at failure = 300+X kN/m?
X = 13
a) Determine the consolidated undrained friction angle
b) What is the pore water pressure developed in the clay specimen at the end of
stage 1 of the test (i.e. consolidation)?
c) What is the angle 0 that the failure plane makes with major principal plane?
d) Determine the normal stress and shear stress on the failure plane

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.
