✦ Synopsis

An approximate numerical method for the analysis of piled raft foundations is presented. The raft is modelled as a thin plate and the piles as interacting non-linear springs. Both the raft and the piles are interacting with the soil which is modelled as an elastic layer. Two sources of non-linearity are accounted for: (i) the unilateral contact at the raft-soil interface and (ii) the non-linear load-settlement relationship of the piles. Both theoretical solutions and experimental results are used to verify that, despite the approximations involved, the proposed method of analysis can provide satisfactory solutions in both linear and non-linear range.

Analysis of piled raft foundations, taking account of their full three-dimensional complexity, can be accomplished by modern finite element analysis techniques. The characteristics of the (preconditioned conjugate gradient) numerical method applied to this problem are analysed, and then the method i

This paper presents a method of analysis for piled raft systems constructed in layered soils. The method presented takes account of the interactions of the raft, piles and soil without the cost of a full threedimensional rigorous analysis. This is done by the use of finite layer methods for the anal

## Abstract A finite‐difference scheme widely used in analysis of pile driving is examined, the scheme is shown to yield peculiar results in simple symmetric impact problems and to inherently posses an imprecise definition of energy balance. A modified difference scheme is suggested and comparisons
