Pile-driving formulas for friction piles in sand
Seven pile-driving formulas are used to calculate capacities of 93 timber, precast concrete, and steel piles, for which field load test data are available; accuracy of formulas varies with type of pile; M. Gates, N.Janbu, and Danish formulas yield highest correlation coefficients, followed closely by Pacific Coast Uniform Building Code and A.Hiley formulas; capacities calculated using Gow and Engineering News formulas correlate poorly with measured capacities; statistical adjustment is applied to formulas to bring them into conformance with field measurements; adjusted forms of Gates, Janbu, and Danish formulas are equally accurate and appear satisfactory for general use.
