A consolidated-undrained triaxial test on a specimen of saturated clay was carried out under an all-round pressure of 600 kPa. Consolidation took place against a back pressure of 200 kPa. The following results were recorded during the test. Draw the effective and total stress paths on p'-p an p – q space, respectively. 01-03 (kPa) 158 279 319 u (kPa) 200 277 388 433

SITUATION 14: After conducting a tri-axial test on a sand sample, the normal and shearing stresses on the failure plane at failure were found to be 400 kPa and 350 kPa respectively.48. Which of the following gives the angle of shearing resistance? a. 38.79 b. 41.19 c. 48.81 d. 53.949. Which of the following most nearly gives the angle of failure plane measured from the major principal plane?a. 69.41 b. 64.40 c. 71.99 d. 65.5950. Which of the following most nearly gives the major principal stress? a. 1331.51 Kpa b. 1414.58 Kpa c. 1130.37 Kpa d. 1171.32 Kp

A specimen of dry sand was subjected to a direct shear test. The normal stress of 120 kN/m2 wasimposed on the specimen. The test was carried out until the specimen sheared, with shearstress at the failure of 75 kN/m2, determine the sand’s angle of internal friction ∅ and the angle ofthe failure plane θ.
