RESPONSE OF PILE GROUP SUBJECTED TO VERTICAL AND LATERAL LOADING – THREE DIMENSIONAL NUMERICAL STUDY

Abstract

The pile soil interaction is sophisticated problem when it solved in a coupled analysis (single analysis). So, the traditional methods for analysis of piles depend on sub-grade reaction between soil and pile do not account the combination between the vertical and lateral loads. Therefore, based on FEM, the computer program PLAXIS 3D Foundation was used to undertake numerical studies on the behavior of single pile and Pile group. The influence of pile group size, pile length, load eccentricity and soil type on the lateral response of piles and pile group as well as group efficiency had been studied. Furthermore, relied on the numerical analysis the relation between soil reaction and soil displacement (p-y curves) was also presented in this study for six types of soil. Insert photo here
