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

In the laboratory test on a clay sample of
thickness 25mm, drained at top only, 50%
consolidation occurred in 11 minutes. Assume
= 0.197, T = 0.405. Find the time required
for the corresponding clay layer in the field of 3m
thick and drained at top and bottom to undergo
50% consolidation. Also, find the time required to
undergo 70% consolidation.

A consolidated undrained triaxial test was performed on a normally consolidated clay with a critical state friction angle of 230. After an initial isotropic consolidation at a cell pressure of 50 kPa, drainage was turned off, the cell pressure was increased to 85 kPa, and the sample was loaded to ultimate conditions. A pore pressure of 55 kPa was measured at ultimate state. What value of major principal total stress was measured at the ultimate state?
