A singly under-reamed, 8-m long, RCC pile (shown in the adjoining figure) weighing 20 kN with 350 mm shaft diameter and 750 mm under-ream diameter is installed within stiff, saturated silty clay (undrained shear strength is 50 kPa, adhesion factor is 0.3, and the applicable bearing capacity factor is 9) to counteract the impact of soil swelling on a structure constructed above. Neglecting suction and the contribution of the under-ream to the adhesive shaft capacity, what would be the estimated ultimate tensile capacity (rounded off to the nearest integer value of kN) of the pile? 8000 mm 400 mm 350 mm 750 mm

Question
A singly under-reamed, 8-m long, RCC pile (shown in the adjoining figure) weighing 20 kN with 350
mm shaft diameter and 750 mm under-ream diameter is installed within stiff, saturated silty clay
(undrained shear strength is 50 kPa, adhesion factor is 0.3, and the applicable bearing capacity
factor is 9) to counteract the impact of soil swelling on a structure constructed above. Neglecting
suction and the contribution of the under-ream to the adhesive shaft capacity, what would be the
estimated ultimate tensile capacity (rounded off to the nearest integer value of kN) of the pile?
