Pile Load Capacity Calculation Using Static Cone Penetration (SCPT) Test Data The safe load capacity of bored cast in situ piles can be calculated using the test data obtained from static cone penetration test as described below. We know that the ultimate load capacity of pile consist of two terms, i.e. End bearing resistance Skin … Read more
Pile Load Capacity Calculation in Weathered or Soft Rock This method of calculating pile load capacity was suggested by Cole & Stroud. Cole & Stroud used ‘N’ values or results of standard penetration tests to find allowable load capacity of the pile in weathered rocks. The formula suggested by Cole & Stroud is given below. … Read more
Pile Load Capacity Calculation Using Standard Penetration Resistance This method of calculating pile load capacity in cohesion less soil (i.e. in sand) was suggested by Meyerhof. Meyerhof suggested the following equation, to calculate the ultimate pile load capacity in saturated sand, using standard penetration resistance (N). In the formula given below the 1st term gives … Read more
The ultimate bearing capacity of a pile is the maximum load which it can carry without failure or excessive settlement of the ground. The bearing capacity of a pile depends primarily on 3 factors as given below, Type of soil through which pile is embedded Method of pile installation Pile dimension (cross section & length … Read more
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
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
