WebbMeyerhof suggested the following methods for estimation of load capacity of the piles for cohesionless soils and cohesive soils. For piles in cohesionless soils, the point-bearing … WebbThe ultimate bearing capacity of a pile used in design may be one three values: the maximum load Q max, at which further penetration occurs without the load increasing; a calculated value Q f given by the sum of …
Webb7 feb. 2024 · Ultimate bearing capacity = Ultimate base resistance + Ultimate skin friction: Qu = Qb + Qs Cohesive soils. Qb for piles in cohesive soils is based on Meyerhof's equation (1951): Qb - Nc x cb x Ab where. Nc = bearing capacity factor, widely accepted as equal to 9.0 Cb = undisturbed undrained shear strength of the soil at base of pile. Webb2 juni 2010 · Meyerhof, G. G. (1976).

Brinch Hansen's bearing capacity theory: Brinch Hansen (1970) provided equations to estimate limit bearing capacity for two separate cases of strength parameters: (1) f > 0, and (2) f = 0 (undrained clay). In addition, for each of these cases there are two separate subcases: (a) Either no horizontal component of load or there is …
