Q. A reinforced concrete circular pile of 12 m length and 0.6 m diameter is embedded in stiff clay which has an undrained unit cohesion of 110 kN/m2. The adhesion factor is 0.5. The Net Ultimate Pullout (uplift) Load for the pile (in kN, round off to 1 decimal place) is
Solution:
Pull out load =αCu.l.p
p= perimeter
l= length
=0.5×110×12×π(0.6)
=1244.07 kN
