A 2-m diameter flexible foundation applies a uniform pressure to the underlying soil of 200 kN/m 2

Question:

A 2-m diameter flexible foundation applies a uniform pressure to the underlying soil of 200 kN/m². Plot the variation of the vertical stress increase below the center of the foundation as determined using both the Boussinesq (Δ_σB) and Westergaard (Δ_σW) solutions up to a depth of z = 5 m. (µ_s = 0.2.)
