“…As a result, a large amount of research has been devoted to this field and sophisticated calculation methods have been put forward, such as the elastic theory method (Poulos and Davis, 1968;Seo and Prezzi, 2007;Seo et al, 2009), load transfer method (Seed and Reese, 1957;Liu et al, 2004;Kim et al, 2007;Zhang et al, 2010;Zhang and Zhang, 2012), shear displacement method (Randolph and Wroth, 1978;Chow, 1989;Mylonakis and Gazetas, 1998), and various other numerical methods (Ai and Han, 2009;Comodromos et al, 2009;Said et al, 2009). However, these existing methods are primarily focused on the calculation of the final value of the settlement, rather than its time-varying behavior.…”

Abstract:A new and simple approach is presented to analyze the time effect in the settlement of single pile and the distributions of pile shaft resistance and pile axial force. First, the viscosity of soil is considered by using a linear damper, and the nonlinear elasticity of pile lateral soil and pile end soil are simulated by using a hyperbola model and idealized elastoplastic model, respectively. Then, the settlement of the pile head, shaft resistance, and axial force along the pile are derived by virtue of a wave equation analysis program based on traveling wave decomposition. Based on the solutions, a parametric study has been undertaken to investigate the influences of the parameters of a pile-soil system on the settlement behavior of a single pile. Finally, the calculated results are compared with the measured results to demonstrate the effectiveness and accuracy of the proposed approach. Note that the presented solution allows for a good prediction of the settlement behavior of a single pile and can provide a reference for the preliminary design of a pile foundation.

“…At present, the following research methods of ground and foundation interaction are used: finite element method (Comodromos et al, 2009), boundary element method (Ai and Han, 2009), infinite layer method based on the superposition principle (Cheung et al 1988), calculation model simplified method (Cairo &Conte, 2006 andZhang et al, 2010), elastic analytical method based on the energy principle (Seo & Prezzi, 2007), data analysis methods based on an artificial neural network (Ismail & Jeng, 2011) and support vector machine (Farfani et al, 2015). The mixed method of the boundary element method and finite element method has been commonly used in theoretical studies by Millán and Domínguez (2009), Vasilev et al(2015).…”

To study the influence of a foundation structure on the ground, the finite layer method of composite ground is derived based on the finite layer method (FLM) theory of the semi-analytic numerical method and the force method principle of elastic material, which is used to analyze a layered ground including multiple internal constraint planes. By simplifying a pile body as a solid constraint composed of four side plane constraints, the composite ground FLM is applied to solve the displacement and stress field of the ground. The change of the ground displacement and stress caused by the addition of a single pile constraint are then discussed, and the influence rules of a pile position on the ground displacement are also determined. Finally, the necessity, rationality and validity of the composite ground FLM are demonstrated by the model test examples of a single pile and pile raft foundation.
