Question:
The average value of a series of uniaxial compressive tests on a soft rock was 33 psi. The average value of the major principal stress in a series of triaxial tests on the same rock under a confining pressure of 95 psi was 355 psi.
a) Plot the stress circles representing the results of these tests on a Mohr diagram and determine the angle of internal friction and the cohesion
b) If the pore water pressure in the samples during the uniaxial compressive tests was 5 psi and during the triaxial test 45 psi, plot the Mohr diagram in terms of effective stresses.
