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
