As per IS-2911-Part1 / Sec-2, the ultimate load carrying capacity (Qu) of pile in cohesive soils is given by the given below, where the first term represents the end bearing resistance(Qb) and the second term gives the skin friction resistance(Qs). Where, Qu = Utimate load capacity, kN Ap = Cross-sectional area of pile tip, … Read more
Piles can either be driven into the ground (driven piles) or be installed in a predrilled hole (bored piles or drilled shafts). The construction of bore cast in situ concrete pile consists of 4 primary phases 1.Pile boring, 2.Reinforcement cage lowering, 3.Flushing 4.Pile concreting. Now we will discuss each phase one by one. 1. Pile … Read more
As per IS-2911-Part1/sec2, the ultimate load carrying capacity of pile, Qu, consists of two parts. One part is due to friction, called skin friction or shaft friction or side shear, Qs and the other is due to end bearing at the base or tip of the pile toe, Qb. The equation given below is used … Read more
