Footing: This is a 3 m wide strip footing, located on the ground surface of an isotropic, homogeneous
layer of soil. The footing places a uniform load of 50 kPa on the ground surface. The unit weight of the soil
is 1,800 kg/m3
and the depth to ground water is 3 m below the ground surface.
Calculate, tabulate and plot all three relevant stress variations – total overburden stress, effective
overburden stress, and final effective vertical stress – on a pressure vs depth diagram
