Recent years, a lot of urbanization is taking place as a result many high rise buildings are constructed and due to scarcity of land , structures are built on soft soils using pile foundation which becomes very costly. So apart from conventional method now geotechnical engineers are going for piled raft foundation in which load from super structure is shared by raft mainly and pile act as settlement reducers. Raft alone has adequate bearing capacity and reduces differential settlement but

It is also an economical method as compared to conventional pile foundation. In present paper experiment and numerical analysis is studied on plain raft and piled raft of different configurations namely with varying various parameters of pile and thus studying load settlement behaviour for different configuration of piled raft foundation experimentally and comparing them with numerical modeling using PLAXIS 2D. This study is useful to decide various parameters required to design piled raft foundation economically.
