“…Budiman and Ahn [13] conducted numerical analyses of single pile and pile group in clayey soils subjected to monotonous lateral loading using the FE program ABAQUS on free head and embedded capped piles. Their results show that pile cap size influences the lateral capacity of single pile, while the pile-soil-pile interaction and the cap embedment depth affects the resistance in the leading pile of the pile group.…”

Groundwater table has an important role in soil–structure interaction problems. However, analysis of laterally loaded single piles has often been conducted by solely considering the mechanics of the soil skeleton or decoupling the interactive mechanics of the soil skeleton and the fluid flux; in other words, most analyses were performed without taking into consideration the coupling effect between the soil skeleton and the fluid flux. To improve our understanding of the hydromechanical coupling effect on laterally loaded single piles, a series of finite element study on laterally loaded single piles in saturated porous media was conducted. The effect of pile cap geometries, cap widths, cap embedment depths, and pile lengths, on the response of laterally loaded single piles was also studied. The loading condition of the pile was found to have a significant effect on the generation of excess pore-water pressure. The lateral displacement and bending moment computed at the maximum excess pore water pressure, which in turn, is equivalent to an undrained analysis, produced the minimum responses among all the other loading conditions. The effect of pile cap geometries was found to be much less significant than anticipated.

The finite element method, with several modifications (e.g., finite elements with Fourier technique, finite elements with substructuring, finite elements with periodic boundary conditions), has also been used quite extensively to model pile groups in elastic and elastoplastic soils (Chow 1987, Shibata et al 1988, Kooijman 1989, Brown and Shie 1991, Bransby 1996, Zhang et al 1999b, Wakai et al 1999, Zhang and Small 2000, Law and Lam 2001, Budiman and Ahn 2005. That apart, the discrete element method (Holloway et al 1981), the finite difference method (Comodromos and Pitilakis 2005) and the variational method (Shen and Teh 2002) have been used to analyze pile groups.…”
