An analysis of the vertical deformation of pile groups

Abstract: A method of analysis is presented which permits the settlement of a pile group under vertical load to be calculated with reasonable accuracy, without the expense of a full rigorous analysis. The method is based on the superposition of individual pile displacement fields, considering the average behaviour down the pile shafts separately from that beneath the level of the pile bases. The displacement fields are determined by means of a recently developed, approximate, closed form solution for the problem of a si… Show more

“…16 where E/E 0 represents the average distribution over a depth of 2.0 m beneath the base of the piles. Moreover, it is now common knowledge that interaction between pile bases is significantly less than interaction between pile shafts (see for example Randolph and Wroth 1979); this leads to significantly reduced pile group settlement predicted by a direct analysis.…”
