A square footing of size 8 8 m is founded at a depth of 2 m below the ground surface in loose to medium dense sand. Standard penetration tests conducted at the site gave the following corrected N60 values. Depth below G.L.. (m) N cor Depth below G.L. N cor 2 4 8 10 11 8 12 16 22 12 12 14 18 16 18 17 20 The water table is at the base of the foundation. Above the water table y = 16.5 kN/m, and y' = 8.5 kN/m. Determine the immediate settlement of the foundation using Schmertmann's method by making use of relationship qe 4Ncor kg/cm, where qe is static cone penetration value in kg/cm. Assume settlement is required at the end of a period of 3 years. A square footing of size 8 8 m is founded at a depth of 2 m below the ground surface in loose to medium dense sand.
