Abstract

Part 1 records the results of over 300 pile tests in chalk, separated into various defined pile categories. The performance of the piles is expressed graphically to facilitate comparison and estimation of pile settlement. Results of special tests are studied so that shaft and base resistance can be evaluated. Various methods of analysis are used to separate the developed values of the components of shaft resistance and end-bearing resistance from a study of particular pile test load settlement curves. Developed factors of safety on the base and shaft and their relationship to settlement are assessed. Also included is a study of dynamic formulae. Two sections described the properties and distribution of chalk, and discuss suitable methods of investigating chalk sites. In Part 2, the studies made in Part 1 are used in the formulation of a design procedure for driven and bored piles.
