A 600 mm diameter and 25 m long driven concrete pile carries a column load of 1200 kN. It is estimated that the shaft carries 900 kN and the point carries 300 kN. Determine the settlement of the pile head using the Poulos and Davis method with the following data: Es = 25 MN/m2, Ep = 30,000 MN/m2 and ?s = 0.2.
A circular pile 0.65m in diameter and 13m long is embedded in loose sand. Site investigation suggests a dry unit weight of 17.35 kN/m3, moisture content of 9% above the water table, specific gravity = 2.65, and a saturated unit weight of 21.46 kN/m3 for the soils beneath the water table (2.75m below the surface). Nq = 95, k=1.35, tan α= 0.35 and FS = 3.0.
