A field vane shear test was conducted in saturated clay. The height and diameter of the vane were 101.6 mm and 50.8 mm respectively. During the test, the maximum torque applied was 0.0168 kN.m
Determine the undrained shear strength of the clay?
A 15-m thick soil has water table 5 m. below the ground surface. The soil has a void ratio of 0.51 and specific gravity of 2.65. Above the water table, the soil has a degree of saturation equal to 44.4%. Direct shear test conducted on the soil shows that the an angle of internal friction of 27.45° and cohesion of 16.26 kPa. What is the potential shear strength (in kPa) on a horizontal plane at a depth of 8 m. below the ground surface? Use stored value. Answer in 5 decimal places.
A saturated specimen of cohesionless sand was tested under drained conditions in a triaxial compression test apparatus and the sample failed at a deviator stress of 482 kN/m2 and the plane of failure made an angle of 60° with the horizontal. Find the magnitude of the principal minor stress in kPa at failure for identical specimen of sand if it is tested under a cell pressure of 200 kPa.
