Hello and hope your help with foundation CEE 430 thanks 

### Text from Image **Problem Statement:** 4. A 4 m x 8 m rectangular footing will be placed on the ground surface as shown in the figure below. The total load acting on the footing will be 900 kN. Determine the consolidation settlement of the foundation. Assume the clay is normally consolidated with \(C_c = 0.3\) and use \(2:1\) method to calculate the stress increase at the middle of the clay layer. ### Diagram Explanation **Diagram Components:** - **Footing Dimensions:** The plan shows a new rectangular footing with dimensions 4 m x 8 m placed on the ground. - **Soil Stratification:** - **Sand Layer 1:** 2.8 m thick with a dry unit weight (\(γ_{dry}\)) of 18 kN/m³. - **Sand Layer 2:** 4.2 m thick with a wet unit weight (\(γ_{wet}\)) of 18.6 kN/m³. - **Clay Layer:** 3.0 m thick with properties: - Wet unit weight (\(γ_{wet}\)) = 18.2 kN/m³ - Initial void ratio (\(e_0\)) = 0.82 - Liquid Limit (LL) = 44 - Plastic Limit (PL) = 20 - **Water Table (W.T.):** Located within the second sand layer. This setup is used to determine the stress distribution and consolidation settlement under the applied load using soil mechanics principles. The problem involves analyzing the effect of the load on various soil strata and calculating the settlement, particularly of the clay layer, utilizing the \(2:1\) stress distribution method.
