Hiley's formula

WebHiley’s formula R=E/ (s+0.5c) is based on the principle of energy conservation in which the energy brought about by hammers during the action of hitting are transferred to piles in ground. When the hammer force and displacement is plotted, the energy absorbed by piles is the area under the curve. Webformula:, 0.1 2 + = s E R r s [safe load, lb, with FS =6 built-in] E r - rated energy, ⋅ft lb; s- penetration per blow, in Used by at least 20 agencies according to 2004 survey Recommended by FHWA, used by at least 7 agencies according to 2004 survey R u = 1. 75 E r log(10N) −100 [ultimate load, ton]
