Study on Behavior of Flexible Raft on Soft Soil Reinforced with Piles

Abstract

This paper explores the relationship of a structure and its base with the soil, and the method of nonlinear analysis developed for the study of the versatile raft base, enhanced by granular piles, which is supported by a granular layer on top of soft soil. The raft is envisioned like a flat rectangle plate. The grainy layer beneath the raft is imagined as just an immiscible shearing sheet. The improved ground is depicted schematically as a series of elementary columns interacting with one another due to some internal friction and/or bonding. The current approach's precision is tested and demonstrated to be precise by contrasting its findings to the outcomes from other established methods of study, ground measurement, but also PLAXIS 3D programme outcomes. The effect of various parameters on the action of a raft resting on a granular layer over soft soil enhanced by granular piles is investigated using a parametric analysis. According to the study, ignoring the interaction of soil shear has a significant impact on raft behavior.
