A footing, 2 m square, rests on a soft clay with its base at a 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 following
properties:
W₁ = 30%, W₁ = 40%, G₂ = 2.70
0°, C₁=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 footing. Natural water table is close to the ground surface.
question 1
A circular concrete pier of 3 m diameter carries a gross load of 3500 kN. The supporting soil is a
clayey sand having the following properties:
c = 5 kN/m². = 30° and y = 18.5 kN/m³. Find the depth at which the pier is to be located such that
a factor of safety of 3.0 is assured. The bearing capacity factor for $ = 30° are N = 30.1, N₁ = 18.4
and N₂ = 22.4.
