Settlement analysis of composite foundation with rigid piles under flexible ground

Zhu Ning

Open publisher page 1 citations

Abstract

A simplified analytical method is presented for nonlinear analysis of the behavior of composite foundation with rigid piles.An elastoplastic relationship between the shaft shear stress and the relative shaft displacementsis adopted.The development of settlement,skin friction,stress and neutral plane on piles is investigated through the proposed approach.Comparisons of the load-settlement responses the finite element and difference calculation methods are given to demonstrate the effectiveness and accuracy of the proposed analytical method.
