Abstract
In a hollow tubular foundation pile a soil plug may develop at the bottom of the pile. This plug consists of soil under a high compressive stress, so that its stiffness and its strength are very large. During pile driving the formation of such a plug may result in a very high driving resistance, which may hinder the driving process. In static conditions the presence of a plug may give a considerable contribution to the bearing capacity of the pile. In this chapter an elementary numerical model is developed for the analysis of the stress transfer in a plug. Before presenting that model two simple analytical models are discussed, one using a linear elastic form of soil-pile interaction, and one using a fully plastic form of pile-soil interaction. The numerical model includes both as limiting cases.
