EXPERIMENTAL STUDY ON FINITE ELEMENT MODEL OF PILE FOUNDATION ON SAND MEDIUM USING ANSYS SOFTWARE

CIVIL ENGINEERING

Pile Foundation which is a composite structure consisting pile and raft has been proved to be an appropriate alternative instead of conventional Raft/ Mat foundations. Raft foundation covers the entire area of the structure, transmitting the entire structural load and reduces differential settlements, whereas piles are relatively long & slender members that transmit foundation loads through soil strata of low bearing capacity to deeper soil ( By skin friction piles) or Rock strata (End bearing piles) where having a high bearing capacity. Here, analysis of free-standing pile group foundation has been carried out by using finite element software ANSYS. For understanding the behavior of pile group foundation parametric studies has been carried out in sand medium by constant pile diameter, different spacing of pile and different pile length with different loading combinations. Project object is to simulate free-standing pile group foundation in sandy soil using Finite Element Analysis to evaluate the deflection & deformations developed under structural load conditions and compare the results. The results of these studies have led to an improved understanding of the soil-structure interaction problem and providing greater confidence for its use in further engineering practice.
