Influence of "Pile-Rocky Massif" Contact on Pile Settlement

Abstract

We study the influence of "pile-rocky massif" contact under the action of axial compressive loads on the basis of the experimental results and numerical simulations. It is shown that, in predicting the behaviors of bored piles in rocky grounds under the action of axial compressive loads, it is necessary to take into account the influence of "pilerocky massif" contact both on its load-carrying capacity and on its settlement. For the numerical analysis of pile settlements, it is proposed to use the shear contact stiffness.
