The results of a CPT test performed for a commercial site are presented in the image (You already classified the soil layer in homework #2). The layer soil type is shown by the legend and corresponding numbers in the figure. A strip footing with a size of 3x30 is built on the surface of the mentioned strata. A 300 kN/m load is acting on the footing. Use Schmertmann's method to compute the settlement of this footing 1 year after construction and 30 years after construction. Please show your calculation for at least one layer if you want use excel software for this problem. For easier calculation use E₂ = 39c- • • Neglect the foundation weight. • Assume the layers are in dry condition. Use unit weight as table below.
