Construction of structures on soft soils having high compressibility, low bearing capacity and low shear strength would cause vertical and differential settlement of structures. Using deep foundation like piles may reduce both the vertical and differential settlements by transferring loads coming from superstructure to hard bearing stratum of soil through friction and/or end bearing action. In current work, numerical analysis is carried out using different mesh configurations available in Plaxis 3D giving input from literature. The mesh configuration which gives reasonable results is compared to field test results available in literature. Further, the same mesh configuration is adopted for present study. To verify the numerical analysis the field load test of 4-piled raft system was modelled and analyzed, and then the analysis results are compared to reported field load test results from available literature. Piles often subjected to axial loads, lateral loads and moments therefore, behaviour of 2-Pile group is numerically analyzed by applying axial and combined axial and lateral loads in finite element program Plaxis 3D. Results from the analysis will be discussed further in detail.
