Aspects of soil-pile interaction under static loads

by Goldsmith, Peter R.

Abstract (Summary)
This model study is concerned with attempting to identify some of the mechanics of pile-soil interaction under the influence of static loads, as a pre-requisite to defining the mechanics of the soil response to pile transmitted dynamic (i.e. seismic) lateral soil loads. The emphasis has been directed at the mechanics of the response of the soil to loads transmitted through the pile, rather than the more usual approach of defining an analytical pile model and assuming a soil response. The work contained herein follows the incremental deformations occurring within a soil mass throughout the process of installation through to the ultimate lateral loading condition. To enable this to be done the comparatively recent developments in soil mechanics involving the application of the techniques of stereophotogrammetry and radiography, have been employed. The study is mainly involved with short rigid models in dry dense sand. A more general aim of the research project has been to attempt to draw the more research orientated and practical aspects of the statically loaded pile problem closer together. To this end, state-of –the-art reviews of both the axial and lateral loading situations have been conducted and an attempt made to relate them to the mechanics of soil response, as identified both in this research project and from full scale tests reported in the literature. An attempt has been made to apply some of the more general observations resulting from the study, to the Type A prediction, (i.e. before the event), of the ground line displacements of a full scale pile under real site conditions when subjected to various loads.
