Initial residual stresses in driven piles existing prior to loading tests consist of driving-induced and reconsolidation-induced stresses. For estimating initial residual stresses which have significant influence on interpreting load-test results, a non-linear simplified Boundary Element Method (BEM) employing hyperbolic models is used. Analytical results for single piles and group piles in stiff clay are shown as a case study. Application to a big project, where long floating driven piles were designed, is also described to show the importance of initial residual stresses in interpreting the loading test of a driven pile in clayey soil.
