Effect of K0 on the settlement of a raft foundation: a numerical study
Effect of K0 on the settlement of a raft foundation: a numerical study
Prediction of settlement remains one of the most studied problems in geotechnical engineering. Even though the use of numerical analysis tools such as Finite Element Method has enabled an improved and convenient means of settlement prediction, the quality of a prediction depends on the efficacy of the numerical analyses and soil constitutive models. Initial ground condition could significantly influence the mechanical behaviour of natural clays in numerical analysis. Due to complexity of stress history undergone by soil deposits, it remains difficult to reconstruct its initial state of stress. In the context of everyday routine design, reliable site measurements of K0 are rarity, and its value remains one of the most difficult parameters to determine. In this paper, a set of 3D finite element analysis cases has been carried out using finite element software Plaxis3D to investigate the effects of K0 on the settlement of raft foundation of varying sizes on London Clay. Issues associated with numerically calculated settlement for different values of K0 are discussed.
