Question

4.1 What is the shear strength in terms of effective stress on a plane within a saturated soil mass at a point where the total normal stress is 295 kN/m2 and the pore water pressure 120kN/m2? The effective stress parameters of the soil for the appropriate stress range are c0 ¼ 12 kN/m2 and 0 ¼ 30. 4.1 What is the shear strength in terms of effective stress on a plane within a saturated soil mass at a point where the total normal stress is 295 kN/m2 and the pore water pressure 120kN/m2?

Explanation / Answer

¼ 295kN=m2

u ¼ 120kN=m2

0 ¼ u ¼ 295 120 ¼ 175kN=m2

f ¼ c0 þ 0 tan

0 ¼ 12 þ 175 tan 30 ¼ 113kN=m2
