A Modified Shear Displacement Method for Calculating Settlement of Single Pile

Abstract

A modified shear displacement method is presented to analyze the load-settlement response of a single pile in homogenous soil using two models. One model adopts a hyperbolic model to simulate the stress-strain relationship of soil under shear stress before failure occurs, and the other model uses a non-linear stress-strain relationship to evaluate the load-displacement behavior of the soil beneath the pile base. Comparisons of the load-settlement responses between the present modified model and the model suggested by Randolph and Wroth are given to demonstrate the effectiveness and accuracy of the proposed modified method.
