Piled Raft Foundation; Soft Soil; PLAXIS 2D; Number of Piles


In the recent years, there are many construction projects which are constructed on soft soil. Because of the characteristics of soft soil, the structures which are built on it are subject to differential settlements. Raft foundation is one of the methods for reducing differential settlement. Piles used with a raft foundation is known as a piled raft foundation system. To reduce the settlements to an acceptable amount, the piles are added. The aim of this study is to analyse the settlements of the raft foundation by increasing the number piles, as the pile raft 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 2D by considering the various number of piles. As a result, the addition of piles could reduce the settlement. It is necessary to consider the optimum number of piles in piled raft foundation system based on the allowable settlements, for its economical design. This analysis has been undertaken to study the behaviour of piled raft foundation under different number of piles. This analysis has been done using PLAXIS 2D software.
