TI  - Numerical Analysis of Piledâ??Raft Foundations on Multiâ??Layer Soil Considering Settlement and Swelling
ID  - scholars16997
N2  - Numerical modelling can simulate the interaction between structural elements and the soil continuum in a piledâ??raft foundation. The present work utilized a twoâ??dimensional finite element Plaxis 2D software to investigate the settlement, swelling, and structural behavior of foundations during the settlement and swelling of soil on various soil profiles under various load combinations and geometry conditions. The field and laboratory testing have been performed to determine the behavior soil parameters necessary for numerical modelling. The Mohrâ??Coulomb model is utilized to simulate the behavior of soil, as this model requires very few input parameters, which is important for the practical geotechnical behavior of soil. From this study, it was observed that, as soil is soft and has less stiffness, the unâ??piled raft was not sufficient to resists and higher loads and exceeds the limits of settlement. Piled raft increases the load carrying capacity of soil, and the lower soil layer has a higher stiffness where the pile rests, decreasing the significant settlement. Further, the effects of (L/d) and (s/d) of the pile and Krs on the settlement are also discussed, detailed numerically under different scenarios. The swelling of expansive soil was also simulated in Plaxis 2D with an application of positive volumetric strain. The aboveâ??mentioned parametric study was similarly implemented for the heaving of foundation on expansive soil. © 2022 by the author. Licensee MDPI, Basel, Switzerland.
