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 Es = 3 qc. ● Neglect the foundation weight. Assume the layers are in dry condition. Use unit weight as table below. ●
