“…The number of equations to solve is 16032. In order to provide a direct comparison with the results provided by Taiebat and Carter (2001), all obtained results are expressed in terms of a dimensional time…”

“…The predicted lateral displacement of the pile head in the direction of the applied load is plotted against the dimensionless time, v T in Figure 9. Results of the analysis using the discrete and continuous Fourier series method suggested by Taiebat and Carter (2001) are also shown for comparison. As it may be observed, the results of the analysis using the discrete Fourier approach are in close agreement with the results obtained in the present analysis.…”

“…The stiffer behavior of a pile in soil with associated flow rule can be attributed to the dilative characteristics of the soil after failure. Expansion of the soil after failure increases confining pressures which in turn increase soil resistance, causing stiffer behavior in comparison to the behavior of soil with non-associated flow rule (Taiebat and Carter, 2001). The predicted load-horizontal displacement curves at the pile head under fully drained (load is applied slowly) and undrained conditions are presented in Fig.…”

“…In order to permit a direct comparison with the results provided by Taiebat and Carter (2001) In the centrifuge test reported by Abdoun (1997), a single pile model (called model N o 3 in the experimental work) was embedded in a saturated soil deposit and submitted to a lateral movement at its base. The experiment was conducted using the rectangular, flexible-wall laminar box container shown in Figure 13(a).…”

“…The main function of piles is to transferred axial an lateral loads from the superstructure to a reliable soil. Thus, several studies have been advocated to the study of soil-pile interaction problems under lateral and axial loads by using simplifying or complex approaches (Taiebat and Carter, 2001, Gu et al, 2016,Khoadir and Mohti, 2014, Chatterjee et al, 2015. Other research groups have focused on the development of simplified expressions for evaluating pile displacements and bending moments along the pile axis (Khodair and Mohti, 2014) by using the subgrade reaction approach (Valsamis 2008, Valsamis et al 2012, Chaloulos et al 2013b.…”

Modeling and simulation of mechanical response of structures, relies on the use of computational models. Therefore, verification and validation procedures are the primary means of assessing accuracy, confidence and credibility in modeling. This paper is concerned with the validation of a three dimensional numerical model based on the finite element method suitable for the dynamic analysis of soil-structure interaction problems. The soil mass, structure, structure's foundation and the appropriate boundary conditions can be represented altogether in a single model by using a direct approach. The theory of porous media of Biot is used to represent the soil mass as a two-phase material which is considered to be fully saturated with water; meanwhile other parts of the system are treated as one-phase materials. Plasticity of the soil mass is the main source of non-linearity in the problem and therefore an iterative-incremental algorithm based on the NewtonRaphson procedure is used to solve the nonlinear equilibrium equations. For discretization in time, the Generalized Newmark-β method is used. The soil is represented by a plasticity-based, effective-stress constitutive model suitable for liquefaction. Validation of the present numerical model is done by comparing analytical and centrifuge test results of soil and soil-pile systems with those results obtained with the present numerical model. A soil-pilestructure interaction problem is also presented in order to shown the potentiality of the numerical tool.

A review is presented of the role of computational mechanics in geotechnical engineering. Included are discussions of the conventional deterministic techniques used for numerical modeling in geomechanics and a brief discussion of the stochastic techniques for dealing with the uncertainties encountered in geotechnical practice. Considerable emphasis is given to the methods commonly used for the solution of boundary and initial value problems. Significantly, the chapter also includes a discussion of the limitations of the various numerical modeling techniques. Constitutive modeling of soil and rock mass behavior and material interfaces is an essential component of this type of computing, and so a review of recent developments and capabilities of constitutive models for geomaterials is also included. Problems involving the interaction of the ground with other engineering structures are also addressed. Some of the concepts described in the paper are illustrated with examples taken from research and practice. Emphasis has been placed on the mechanical behavior of soil, but it is noted that many of the models and techniques described also have application in rock mechanics and rock engineering.
