The effective stress parameters for a fully saturated clay are known to be c'=10 kN/m and Phi' (internal friction angle) =29°, In an unconsolidated-undrained triaxial test on a specimen of the same clay the all-round pressure was 110KN/m and the principal stress difference at failure was 190KN/m2. What was the value of pore water pressure in the specimen at failure? O A. The alue of pore water pressure in the specimen at failure = 29 kPa O B. The alue of pore water pressure in the specimen at failure = 22 kPa O C. The alue of pore water pressure in the specimen at failure = 20 kPa O D. The alue of pore water pressure in the specimen at failure = 27 kPa

Question
Transcribed Image Text:The effective stress parameters for a fully saturated clay are known to be c'=10 kN/m- and Phi (internal friction angle) =29°. In an
unconsolidated-undrained triaxial test on a specimen of the same clay the all-round pressure was 110KN/m- and the principal stress difference at
failure was 190KN/m2. What was the value of pore water pressure in the specimen at failure?
O A. The alue of pore water pressure in the specimen at failure = 29 kPa
O B. The alue of pore water pressure in the specimen at failure = 22 kPa
O C. The alue of pore water pressure in the specimen at failure = 20 kPa
O D. The alue of pore water pressure in the specimen at failure = 27 kPa
