- A strip footing is founded on sand having strength parameters (Φ =40⁰ and c = 0 kPa). Dry and saturated unit weights of the soil are 17.8 and 21 kN/m³ respectively. The foundation is designed to to carry a load of 4.8MN/m at a Factor of safety against general shear failure of 3. The footing depth is 1.5 m and the water table is 5 m from the surface.
a) Determine the minimum footing width (m) to satisfy the design requirements (2 d.p). Show all working
b) Is water table affecting foundation support?
c) Is water table affecting foundation support? Verify your assumption. Use unit weight of water of 9.8 kN/m3.

Q2
A concrete strip footing with a width of B is
founded at the depth of D, below the surface of a
level site. The water table is at a depth of d
below the base of footing. The soil at the site consists of clay
having the following properties:
The unit weight =
gt, the
undrained cohesion = cu, the undrained
friction angle = fu,
the drained cohesion = c′ and the drained friction
angle = f′
