SETTLEMENT ANALYSIS OF PILE FOUNDATION USING PLAXIS 3D

Abstract

In recent years, there are many construction projects which are constructed on the soft soil. Because of the characteristics Sentimental or soft soil, the structures which are built on that are subject to differential settlements. Foundation is one among the methods for reducing differential settlement. To reduce the settlements to a suitable amount, the piles are added. In this project, the aim is to analyze the settlements of the pile foundation by increasing the number piles, as the pile foundation, under the same loading, with or without considering the water table below the top surface. The numerical analysis has been done by finite element method using PLAXIS 3D by considering the varied number of piles. As a result, the addition in the number of piles could reduce the settlement. It is necessary to think about the optimum number of piles in pile foundation system supported the allowable settlements, for its economical design. This analysis has been undertaken to study the behavior of pile foundation under different number of piles. This analysis has been done using PLAXIS 3D software.
