Behaviour of Laterally Loaded Pile Group Study by Numerical Investigation

Abstract

Piles under tall structure like chimneys, multistoried building and jetty structure etc. experience high lateral load. In those situations piles are to be properly designed against lateral load. With this in view, an attempt has been made in the present investigation to gain an insight into the behaviour of laterally loaded piles in cohesionless soil. An experimental investigation has been carried out with single pile and pile group model tests. The p-y method of analysis models, nonlinear behaviour, and is an effective method of designing deep foundations subjected to lateral loads, displacements and bending moments calculated using p-y analysis have usually been found to be in good agreement with field measurements. Numerical analysis has also been adopted by finite element method with the help of SoilWorks2D geotechnical software. An attempt has been made to study the variation of lateral loads with various design parameters like slenderness ratios (L/d), pile material, density, pile spacing, pile group and middle layer variation. Lateral displacements, bending moments, shear forces and soil reactions predicted by numerically have been found to be in good agreement with the case study the calculated values.
