Calculation of Soil Stresses under Various Pile Sectional Configurations

With development of piling technology, various pile sectional configurations are adopted in the pile industry practice. The soil stresses induced by the piles of various sectional configurations are significantly different. In this paper, the solutions for the induced soil stresses were proposed for Y-shaped pile, closed- and open-ended pipe piles, triangular-shaped pile, rectangular pile, and square pile. The calculation of soil stresses is based on the Mindlin stress solution and Geddes methodology for derivation of soil stresses. It is assumed that the pile end bearing and shaft resistance are uniformly distributed across the pile tip area and shaft perimeter, respectively. The numerical software Mathematica (Nintegrate) was used to provide integrations to the derived theoretical solutions.
