An efficient approach for settlement prediction of pile groups

摘要

The paper presents exact closed form solutions for estimating the settlement of single and group piles in non-homogeneous soil, using a load transfer approach derived from elastic conti- nuum theory. The effects of load transfer factor have been explored in detail to account for the effect on a finite depth of compressible soil and non-homogeneity of soil profiles. Interaction fac- tors between pairs of piles, and overall settle- ment ratios for pile groups of various geometries, are evaluated from the solutions and are shown to be consistent with those obtained from a full boundary element approach.
