1. The results shown in Table were obtained at failure in a series of triaxial tests on speci mens of a saturated clay initially 38 mm in diameter by 76 mm long. Determine the valu es of the shear strength parameters with respect to (a) total stress and (b) effective stres S The initial values of length, area and volume for each specimen are: lo 76 mm; Ao=1135 mm²; Vo = 86 x 103 mm³ (a) (b) Type of test Undrained Drained All-round pressure (kN/m²) 200 400 600 200 400 600 Axial load (N) 222 215 226 403 848 1265 Axial deformation (mm) 9.83 10.06 10.28 10.81 12.26 14.17 Volume change (ml) I coo 6.6 8.2 9.5 625​
