TLDR
In this article, an approximate closed-form solution has been obtained to the problem of a vertically loaded pile in a linear elastic soil by uncoupling the load-transfer for the pile into separate shaft and base components.Abstract:
An approximate closed-form solution has been obtained to the problem of a vertically loaded pile in a linear elastic soil. This solution has been derived by uncoupling the load-transfer for the pile into separate shaft and base components. Throughout the development of the analysis, well-proven numerical techniques have been used to verify that the assumptions made are reasonable. The final form of the solution gives the load-settlement ratio of the pile in terms of the pile geometry and stiffness and soil stiffness. The analysis has been used to back-analyze pile tests, enabling immediate estimates of the soil stiffness profile to be made from the measured load-settlement curve of the pile. The application of the method to pile design is demonstrated—design curves being sketched for piles of different geometries in two typical soft clay deposits.read more

Science and empiricism in pile foundation design
TL;DR: In this article, the authors address the degree of confidence we can now place on the conceptual and analytical frameworks for estimating pile capacity, and on the quantitative parameters required to achieve a design, restricted to driven piles in clays and siliceous sands.
Artificial neural network applications in geotechnical engineering
TL;DR: A review of the literature reveals that ANNs have been used successfully in pile capacity prediction, modelling soil behaviour, site characterisation, earth retaining structures, settlement of structures, slope stability, design of tunnels and underground openings, liquefaction, soil permeability and hydraulic conductivity, soil compaction and soil swelling and classification of soils.

Geotechnical Analysis of Heat Exchanger Piles
TL;DR: In this paper, the authors present a geotechnical numerical analysis method based on the load transfer approach, which assesses the main effects of temperature changes on pile behavior and the occurrence of critical design situations.

Analysis of vertically loaded pile groups
TL;DR: In this article, an approach for the analysis of linear and non-linear responses of vertically loaded pile groups is presented, where the soil behaviour of individual piles in modelled using load-transfer curves and the pile-soil-pile interaction is determined based on Mindlin's solution.
