A computational model of soil-pile interaction behavior in pile and pile group foundations is reported in this document. Particular attention was paid to making the model simple and capable of taking into account nonlinear soil behavior, such as gapping and slippage between soil and pile, and the cyclic behavior of soil. The model was developed within the frame work of the Winkler model defined by plane strain conditions. In the model, the soil is divided into a number of layers and, in each layer, the soil model is divided into two parts. One is an inner field model, which accounts for nonlinear characteristics, and the other is a far field model formulated using time domain plane strain solutions based on the Fourier transform of frequency domain solutions. Dynamic loads are applied at the pile head or heads. In order to analyze transient dynamic response in a rigorous manner, the model was formulated in the time domain using a step-by-step method. A transfer matrix approach was also adopted in the response computation.Subjects--Topical Terms:

520 $a A computational model of soil-pile interaction behavior in pile and pile group foundations is reported in this document. Particular attention was paid to making the model simple and capable of taking into account nonlinear soil behavior, such as gapping and slippage between soil and pile, and the cyclic behavior of soil. The model was developed within the frame work of the Winkler model defined by plane strain conditions. In the model, the soil is divided into a number of layers and, in each layer, the soil model is divided into two parts. One is an inner field model, which accounts for nonlinear characteristics, and the other is a far field model formulated using time domain plane strain solutions based on the Fourier transform of frequency domain solutions. Dynamic loads are applied at the pile head or heads. In order to analyze transient dynamic response in a rigorous manner, the model was formulated in the time domain using a step-by-step method. A transfer matrix approach was also adopted in the response computation.
520 $a Development and formulation of the proposed model was verified by using rigorous solutions and more rigorous numerical methods such as finite element and boundary element methods in both the frequency and time domains. Analyses were conducted for both linear and nonlinear conditions of the soil. Furthermore, using experimental results obtained from full-scale tests, the developed formulation for the pile response analysis was verified.
520 $a Most of the above comparisons were made on the global force-displacement relation, expressed as response behavior. Most studies on pile and pile group foundations have been conducted on experimental or theoretical aspects individually, and it is important to compare the analytically obtained behavior with the behavior observed in experimental studies for developing design methods for pile foundations. After development and verification of the computational model for pile response, it is evident that this model may be a very efficient and indispensible tool for the design of pile and pile group foundations.
