Transcribed Image Text:A footing, 2 m square, rests on a soft clay soil with its base at depth of 1.5 m
from ground surface. The clay stratum is 3.5 m thick and is underlain by a
firm sand stratum. The clay soil has the following properties:
W₁ = 30%; w₁ = 40%; G = 2.70; p = 0; c = 0.5 kg/cm²

It is known that the clay stratum is normally consolidated. using Skempton's
equation, determine the net safe bearing capacity of the footing. Compute
the settlement that would result if this load intensity were allowed to act on
the footing. Natural water table is quite close to the ground surface.
