$### Example Problem for Predicting Footing Settlement Using Meyerhof’s Formulas **Problem Statement:** Suppose the soil beneath the footing is now a sand with an average Standard Penetration Test (SPT) $ N_{60} $ of 28. Predict the footing settlement (in inches) using Meyerhof’s formulas. **Diagram Explanation:** - The diagram represents a cross-section of a soil profile beneath a footing. - There is a vertical load $ P = 72 $ kips acting downward on the footing. - Dimensions of the footing are 6 feet wide and situated 2 feet below the ground surface. - The top layer under the footing is sand with a unit weight $ \gamma = 118 $ pounds per cubic foot (pcf), and an $ N_{60} $ value of 28. - The sandy layer has a depth of 18 feet before transitioning to a gravel layer. **Key Parameters in Diagram:** - **Load (P):** 72 kips - **Footing Width:** 6 ft - **Depth to Sand Layer:** 2 ft - **Depth of Sand Layer:** 18 ft - **Unit Weight of Sand (γ):** 118 pcf - **SPT N-Value for Sand (N60):** 28 - **Underlying Material:** Gravel This problem involves calculating the expected settlement of the footing using Meyerhof’s empirical formulas, taking into account the characteristics and depth of the sand layer directly beneath the foundation.$
