5.5 The results below were obtained at failure in a series of consolidated-undrained (CU) triaxial tests, with pore water pressure measurement, on specimens of a fully saturated clay. Determine the values of the shear strength parameters c & pand c' & #. If a specimen of the same soil were consolidated under an all-round pressure of 250 kPa and the principal stress difference applied, what would be the expected value of principal stress difference at failure? 03 (kPa) 01-03 (kPa) u (kPa) Based on effective stress -Sin-ยน(0.4305) = 25.5%; c' -a/cos = 0.199 kPa 150 103 82 Based on total stress principal stress difference = 169.62 kPa 300 202 169 450 305 252 600 410 331
