Three specimnens of clay having a small air-void content were tested in the shear box. Shear loading was started immediately after the application of the normal load and was completed in 8 minutes. The results are as follows: Normal Stress (kN/m2) Shear stress at failure (kN/m2) O Find the apparent cohesion of the clay. Find the angle of shearing resistance of the clay.

Q.9 An unconfined compression test was conducted on an undisturbed sample of clay. The initial area of the specimen is 1105 mm?. The load at failure measured by the proving ring was 32N and axial strain at failure was 0.162. The undrained shear strength of the clay will be
a consolidated tri-axial test was conducted on a normally consolidated clay. the results were as follows: chamber confining pressure = 316 kPa, deviator stress = 424 kPa. compute for the shear stress on the failure plane in kPa.
A drained triaxial compression test on a saturated clay yielded the effective shear strength parameters as c' = 15 kPa and o'= 22°. %3D Consolidated Undrained triaxial test on an identical sample of this clay at a cell pressure of 200 kPa developed a pore water pressure of 150 kPa at failure. The deviator stress (expressed in kPa) at failure is
5. A consolidated, undrained triaxial test is being caried out on a normally consolidated clay where c = 0 and 41= 26'. The triaxial specimen was consolidated under a cell pressure of 300 kPa and backpressure of 80 kPa. Skempton's A parameter at failure is estimated to be 0.80. The drainage valve has since been dosed and the vertical deviator stress increased to failure. What would be the deviator stress and pore water pressure at failure?
