8.9 A continuous foundation on a deposit of sand layer is shown in
Figure P8.9, along with the variation of the modulus of elasticity of
the soil (E.). Assuming y = 18 kN/m³ and C₂ for 10 years,
calculate the elastic settlement of the foundation using the strain
influence factor method of Schmertmann et al. (1978).
