The shear strength of a normally consolidated clay can be givenby the equation ï´f = ï³ï‚¢ tan 30ï‚°. A consolidated-undrained triaxialtest was conducted on the clay. Following are the results of thetest:
Chamber confining pressure = 100 kN/m2
Deviator stress at failure = 80 kN/m2
Determine
a) Consolidated Undrained friction angle (ï¦CU), (6 points)
b) Using formula, calculate shear and normal stresses on thefailure plane inside the soil sample, (6 points)
c) Pore water pressure developed in the clay specimen at failure.(8 points)
