A clay soil specimen when tested in unconfined condition gave an unconfined compressive strength of 100 kN/m2. A specimen of the same clay with the same initial condition is subjected to a UU triaxial test under a cell pressure of 100 kN/m2. The axial stress (in kN/m2) at failure would be

The correct answer is B.
An unconfined compressive strength qu = 100 KN/m2.
for uu test σ1/σ3=σ1/'σ3=qu
σ1=σ1= 100 + 100 = 200 KN/m2.
An unconfined compressive strength qu = 100 KN/m2.
for uu test σ1/σ3=σ1/'σ3=qu
σ1=σ1= 100 + 100 = 200 KN/m2.

C=UCS/2.
= 100/2,
= 50.
σ1 = σ3 tan^2x + 2C tanx.
σ1 = 100 + 100
= 200.
= 100/2,
= 50.
σ1 = σ3 tan^2x + 2C tanx.
σ1 = 100 + 100
= 200.
