A 12 m long, 300 mm diameter concrete pile is driven in a uniform deposit of dense sand ('= 40°). The water table is at a great depth and is not likely to rise. The average dry unit weight of sand is 18 kN/m³. Using Na values of Berezantsev, calculate the safe load capacity of the pile with a factor of safety of 2.5.
