A footing of size 1.5×2 m is located at depth 1.2 m on a soil
with bulk unit weight of b=16.8 kN/m3 and sat = 17.6 kN/m3, c’ = 80
kN/m2 and ’ = 0. Determine the gross allowable load of the footing
for (a) ground water table well below the foundation base, and (b)
ground water table at the ground surface. Compare the results to
see if in this case, the position of ground water table has an
effect on the bearing capacity.

A square footing 1.5m X 1.5m is located at a depth of 1.0m. The
soil has the following properties: γ = 17.5kN/m3, c= 20kN/m2 and Φ
= 34o. The footing base and ground are horizontal. if the
horizontal component of the weight = 20kN acting at the height of
4m parallel to the side of footing, and vertical component is
500kN, determine ultimate bearing capacity and factor of safety.
