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...
