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-drained triaxial test was conducted on an overconsolidated clay sample.
The sample failed in test 1 at 01=200 kPa and 03=130 kPa, and in test 2 at o1=400 kPa and
03=290 kPa. Determine the undrained and drained friction angles and cohesion for the
assumption that the Skempton's pore water pressure parameter A=0.45. Also, for a CU test on
the same soil, determine o1, 1', 03', and excess pore water pressure u for 03=340 kPa.
