A consolidated undrained (CU) triaxial compression test (TXC) was conducted on a specimen of saturated clay. The specimen was isotropically consolidated to a total cell pressure, σcell of 400 kPa. The backpressure was u0 = 100 kPa. At failure, the total pore water pressure was u = 90 kPa and the deviator stress was (σ1 − σ3)f = 526 kPa. Determine: a. The principal effective stresses, σ1′ and σ3′, at failure b. The friction angle, φ′ (secant method). c. The...

8. A sandy soil specimen is subjected to a Consolidated Drained (CD) triaxial test. Confining pressure of 500 kPa is applied to the cell and the sample was sheared to failure. The deviatoric stress at failure was recorded as 1400 kPa. Determine the principal stresses at failure and the angle of shearing resistance for this soil. (20 points)
