Abstract

The pile-soil stress ratio is a key parameter in pile-soil composite foundations for evaluating bearing capacity, settlement, and reinforcement effect. To reduce significant errors of the traditional Terzaghi method under small deformations, this study introduces an improved approach by revising the slip surface load transfer function. A new stress calculation formula is derived using basic assumptions and equilibrium-deformation coordination equations. Field tests, parameter sensitivity analysis, and comparison with measured data confirm the method’s validity. Results show the time-dependent behavior of pile-soil stress ratios and the influence of different parameters. The proposed method better captures non‑limit soil arching under small strains, offering a reliable reference for stress analysis in composite foundations.
