Q1:

For the strip footing on a saturated clay, for the given failure surface as shown in the below figure, the bearing capacity equation takes the form : (where Cu - undrained shear strength φu - angle of internal friction B - width of strip footing qc - ultimate bearing capacity of soil)

A 5.7 Cu

B 5.14 Cu

C 4π Cu

D 2π Cu

ANS:B - 5.14 Cu

According to Skempton Value for Nc=5.14(strip footing) and 6.20(square or circular footing) for φu=0 and D=0.
