2.1 Introduction
Pile foundations have been used for many years, and as a result a large number of design approaches have been proposed to predict their capacity. These approaches range from simple empirical approaches to sophisticated dynamic finite element analyses, with new methods introduced every few years. Darrag (1987) summarized most of the widely recognized design methods.


Empirical pile design methods, where pile capacity is correlated to in situ tests, have been popular, particularly in Europe. The most widely used methods are based on the cone penetration test (e.g. Notingham 1975), the standard penetration test (e.g. Meyerhof 1976), and the pressuremeter test (e.g. Sellgren 1982). In situ tests reflect, to some extent, field conditions but fail to model and/or measure some of the important parameters that influence pile behavior. Thus, empirical methods often give good predictions when correlated with load test results on a regional basis, but tend not to excel as a generalized prediction method.
