A soil has c′ = 5 kPa and f′ = 32°. The effective stress at a point in the soil is 125 kPa. Com-pute the shear strength normal to this stress at this point.
A soil element is loaded from state A to B. The stress values for the two states are A(p'=50 kPa, q=20 kPa), and B(p'=280 kPa, q=120 kPa). The bulk modulus of the soil is 1000 kPa, and its shear modulus is 1300 kPa. Work out the volumetric strain increment from the loading.
A soil specimen is subjected to a tri – axial test. The soil specimen is cohesionless. If the shear stress that
causes failure is 300 kPa. and the normal stress at failure is only 500 kPa
5. Determine the angle of shearing resistance in degrees
6. Determine the angle that the failure plane measured from the major principal plane.
7. Determine the total axial stress in kPa at which failure is expected to occur.
