ANALYSIS OF PILED RAFT FOUNDATIONS IN CLAYEY SOILS USING FINITE ELEMENT AND ANALYTICAL METHODS

Raft foundation may cause excessive settlement although it has an adequate bearing capacity. Using the combination of raft and pile foundation as named piled raft foundation system may be considered as the good alternative solution for this problem. This study analysed the settlement of piled raft foundation by considering the various number of piles and loading intensity using finite element method and analytical method. In this study, the finite element method was conducted using PLAXIS software and Poulos method were applied for the analytical method. Finally, the results from both methods were compared and conclusions are also made. The settlement analyses using both methods indicate different results. The finite element method shows the smaller settlement than the other method.
