“…Overall, Figs. 2 and 3 show a favourable agreement of PGROUPN with the boundary element solution of Kuwabara [17], the variational approach of Shen et al [31], and the hybrid analysis of Ta and Small [35] which combines the FEM for the raft with the finite layer method for the piles.…”

“…The performance of a piered-raft foundation in China was also reported by Zhang and Zhao (2000). Kuwabara (1989) performed a boundary element analysis based on an elastic theory to analyze the behaviour of piled raft foundation subjected to vertical load. Ta and Small (1998) presented a method of analysis for piled raft foundations on layered soils which combine both FEM for the analysis of raft andˆnite layer method for soilpile groups.…”

Foundation engineering emerged as a discipline of modern engineering science in 1940s.Design and analysis as well as practice of foundation engineering have made a signiˆcant progress up to the present time.This paper gives an overview of the development of foundation engineering, mainly referring to papers published in Soils and Foundations.The paper describes the theoretical development of foundation analysis and a recent increasing trend of foundation practice of adopting various hybrid foundations.The paper points out the importance of environmental considerations in foundation design and practice, including low noise and vibration reduction, reuse of existing foundations and use of natural energy through foundation elements.The paper then provides authors'views of future directions in foundation studies and practice.

“…This approach reduced the number of equations to be solved compared to using finite element (FE) or finite difference methods, and limited interpolation errors to the boundaries. To obtain the behavior of piled rafts in homogeneous elastic soil, Kuwabara [24] performed BE analysis based on the elastic theory. In his model, the raft was assumed to be rigid, and the pile was discretized into a series of shaft and base elements.…”

Piled raft foundations are among the most commonly used support structures for offshore projects. When a raft foundation alone does not satisfy the design requirements, piles may be added to improve the ultimate load capacity and the settlement performance of the raft. In this study, design criteria were developed for the undrained behavior of a piled raft system based on an examination of average and differential settlements, raft bending moment, and pile butt load ratio. Raft settlements were evaluated by a series of three-dimensional finite element analyses. The average settlement values for the piled raft were highly influenced by the number of piles and the raft thickness. Optimal design configurations of piles for cohesive soils are discussed. Increasing the pile spacing decreased the pile butt load ratio by allowing for a more uniform load distribution between the piles.
