A circular pile 0.45m in diameter and 15m long is embedded in a layer of dense sand. The soil has the following properties: Dry unit eight is 18 kN/m3and saturated unit weight is 21 kN/m3(water table is 4m below from the ground surface), Nq=85, k=1.25, tan αα = 0.45 and FS=2.5
a) Calculate the end bearing capacity
b) Calculate the frictional resistance
c) Calculate the allowable load
