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...

The effective stress parameters for a fully saturated clay are known to be c'=17KN/m3 and phi'=30degrees. In an unconsolidated undrained triaxial test on a specimen of the same clay, the chamber pressure sigma3 was 100KN/m2 and the principal stress differene (sigma1-sigma3) at failure was 180KN/m3. What was the value of pore water pressure in this specimen at failure?
