Question

A square footing supporting a new building applies a uniform pressure of 200 kPa on the ground surface. The water table is at the ground surface and the site is underlain by a homogeneous sand deposit. Based on the bulbs of pressure developed below the footing depicted in the figure below, calculate the vertical total stress in kPa at point C (acceptable tolerance = 2%).
