SITUATION: A precast concrete pile 16 m long has a diameter of 400 mm. The pile is driven through layers of clay and a dense compact sand with the upper layer which is clay having a thickness of 5 m and a unit weight of 16 kN/m³. Water table is at the bottom of the clay layer. Saturated unit weight of sand is 18 kN/m?, with a bearing capacity factor of 72 and a lateral pressure factor for compression of 1.24. Angle of friction of the concrete pile is 28°. Neglect skin friction on the clay layer. Determine the ultimate frictional resistance of the pile. A 1109.70 kN 1106.23 kN 1266.55 kN D 1218.32 kN
