CE Board HGE Problem 30 (Hydraulics and Geotechnical Engineering)

(CE NOV 2023) A Tri-axial shear test was performed on a well-drained sand sample. The normal stress on the failure plane and the shearing stress on the failure plane were determined to be 50 kPa and 30 kPa, respectively.

a. Determine the angle of internal friction of the sand

b. Determine the angle, in degrees, of the failure plane with respect to the horizontal plane

c. Determine the axial stress applied to the specimen
