DIAZ-SEGURA, EDGAR GIOVANNY. SIMPLIFIED METHOD TO ESTIMATE THE ULTIMATE LOAD OF PILES UNDER VERTICAL AXIAL LOAD ON SAND. Dyna rev.fac.nac.minas [online]. 2013, vol.80, n.179, pp.109-115. ISSN 0012-7353.

A series of finite element analysis were carried out to study the response of piles under axial vertical load supported on ten types of sands in dry and saturated conditions. From these results, a simplified method was proposed to estimate the ultimate load in bored piles on sand in terms of diameter and length of pile, unit weight of soil, saturated conditions, and indirect measurements of the shear strength derived from the relative density and N-value from SPT. The proposed method, based on 180 cases analyzed, provides a precision of 92%, and constitutes a complementary simplified design tool to estimate the ultimate load of bored piles on sand.
