Two identical specimens, 4 cm in diameter and 8 cm high, of partly saturated compacted soil are test in a triaxial cell. The first specimen fails at an additional axial load (i.e., deviator load) of 720 N under a cell pressure of 100 KN/m² The second specimen failed at an additional axial load of 915 N under a cell pressure of 200 KN/m². The increase in volume of the first specimen at failure is 1.3 ml and it shorten by 0.6 cm, at failure. The increase in volume of second specimen at failure is 1.7 ml, and it shortens by 0.8 cm at failure. Determine the value of apparent cohesion and the angle of shearing resistance. 7

Two identical specimens, 4 cm in diameter and 8 cm high, of partly saturated compacted soil are
test in a triaxial cell. The first specimen fails at an additional axial load (i.e., deviator load) of 720
N under a cell pressure of 100 KN/m² The second specimen failed at an additional axial load of
915 N under a cell pressure of 200 KN/m². The increase in volume of the first specimen at failure
is 1.3 ml and it shorten by 0.6 cm, at failure. The increase in volume of second specimen at failure
is 1.7 ml, and it shortens by 0.8 cm at failure. Determine the value of apparent cohesion and the
angle of shearing resistance. 7
