1. Shown in the figure are the plan and cross section of a column and its foundation. The column has to take 400 kips load. Geotechnical investigation revealed the following

soil properties: \begin{aligned} &\text { For Clay: }\\ &\gamma_{\mathrm{sat}}=118 \mathrm{pcf} \quad \mathrm{E}_{\mathrm{s}}=1200 \mathrm{psi} \end{aligned} \text { Poisson's ratio }=0.4 \begin{array}{llll} \phi^{\prime}=0^{0}, & \mathrm{c}^{\prime}=1.25 \text { tsf } & \mathrm{G}_{\mathrm{s}}=2.66, & \mathrm{w}=35 \% \end{array} a) Please calculate the total settlement of the foundation also. Consider elastic settlement only. \begin{array}{llll} \text { For sand layer: } & \gamma=115 \mathrm{pcf} & \gamma_{\text {sat }}=122 \mathrm{pcf} & \mathrm{E}_{\mathrm{s}}=3500 \mathrm{psi} \end{array} \text { Poisson's ratio }=0.4 \quad \phi^{\prime}=35^{0} \quad \mathrm{c}^{\prime}=0
