Abstract

Abstract

Based on the assumption of elastic pile-pile interaction, the pile-cap-soil interaction was analyzed by the shear displacement method, and an analytical method was then established to research bearing characteristics of group pile foundations embedded in stratified soil considering the reinforcement and barrier effects between piles and soil. Comparisons of the calculated results by the proposed method with the one by the finite element method and measured results, it was verified to be feasible.
- group pile foundation,
- stratified soil,
- pile-cap-soil interaction,
- bearing characteristic
