Meyerhof bearing capacity factors for piles

Webb7 dec. 2024 · q u = Ultimate end-bearing capacity. c = Cohesion of soil. q = Effective soil pressure. γ = Soil unit weight. B = Cross-sectional depth or diameter. N c, N q, N γ = Bearing factors. Since q u is in terms of load per unit area or pressure, multiplying it by the cross-sectional area of the pile will result in the end-bearing load capacity (Q p ... WebbIntroduction. Piles are structural members that are made of steel, concrete, or timber. They are used to build pile foundations, which are deep and which cost more than shallow …

WebbThe bearing capacity Eq. (12.6) developed by Terzaghi is for a strip footing under general shear failure. Eq. (12.6) has been modified for other types of foundations such as square, circular and rectangular by introducing shape factors.

WebbFor calculating the bearing capacity under the lowermost helix, the variable ‘d’ may be omitted from Equations [1] and [2], assuming the formation of a soil plug within the base of the screw pile shaft. The value of the bearing capacity factor in cohesive soil, Nc, is typically taken as 9.0 (CFEM 2006). In WebbN c, N q, and N γ depend on the roughness of the base of footing, shape of the footing in addition to D f and ɸ. Table 18.3 gives the Meyerhof’s bearing capacity factors for different values of ɸ. The ultimate bearing capacity, given by Meyerhof’s theory, is close to the experimental values. 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. dhhs manual policy nc
