Comparative Study of Pile-Soil Interaction Analysis Methods
Applied Mechanics and Materials, 2012m-method is a widely used method for pile-soil interaction analysis. The main shortcoming of traditional m-method is ignoring the non-linear of soil. The actual relationship between the m and the displacement of pile (y) caused by loads is non-linear; however, it is unreasonable to used a linear curve and a fixed value of m during the calculation.

Iterative analysis of pile–soil–pile interaction
Géotechnique, 1987Consistent formulations of direct and iterative methods of pile group analysis are presented. The iterative methods are derived from the same equilibrium and compatibility equations as the direct methods but are cast in different forms. These new iterative methods highlight the shortcomings of some existing iterative methods of analysis, although ...

Coupled pile-soil interaction analysis in undrained condition
Journal of Central South University, 2013The effective stress method is developed to predict the axial capacity of piles in clay. The effective stress state changes due to the resulting pore pressure change and therefore, the strength and stiffness of the soil will change. In this work, the finite element method is utilized as a tool for the analysis of pile-soil systems in undrained ...

Modeling Pile-Soil Interaction Using Contact Surfaces
2001Pile foundations are quite effective, especially in weaker soils, for transferring the structural loads into the underlying ground. The current procedures for pile design are generally semi-empirical, based on elastic theories and pile load test data. Finite element method (FEM) is a valuable tool in modeling load-deformation characteristics of piles ...

SEISMIC PILE-SOIL INTERACTION: EXPERIMENTAL RESULTS VS. NUMERICAL SIMULATIONS
Proceedings of the 4th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering (COMPDYN 2013), 2014The present analytical work discusses the outcomes of a series of 1-g shaking table experimental tests that were carried out to validate numerical models formulated for kinematic and inertial interaction effects on pile-supported systems. Towards this aim, pile models in layered sand deposits were built in the laboratory; such models were subjected to ...

A Simplified Procedure for the Dynamic Analysis of Pile-Soil-Structure Interaction
Civil-Comp Proceedings, 2013Soil structure interaction problems can be addressed through a sub-structure approach in which the structure is modelled using a finite element approximation and the soil is represented through frequency dependent impedance functions. In this idealization the equations of motion of the overall system are frequency dependent and the rigorous evaluation ...

Effect of Subsoil Liquefaction on Analysis of Pile-Soil Dynamic Interaction
Advanced Materials Research, 2011In order to analyze the effect of subsoil liquefaction on the seismic response of pile foundation, typical computation model in liquable ground was set up. Based on different constitutive models of the foundation soil before and after liquefaction and considering the nonlinear relation of pile-soil interaction, the dynamic finite difference analysis of

Interaction of BEM analysis and experimental testing on Pile-Soil Systems
2003This work considers some important modelling problems for soil-pile systems via application of the Boundary Element Method (BEM). Among these are the correct definition of the number and shape of elements to be used in the discretisation of the pile surface and of the parameters which influence them, the number and shape of elements needed for the ...
