ANALYSIS OF GRANULAR BEHAVIOUR USING FINITE ELEMENTS

A finite element method of analysing a granular pile has been presented in which a limiting pile-soil interface strength can be specified. Both the pile and soil are treated as elasto-plastic materials. The soil is taken to be purely cohesive while the pile is treated as a purely frictional dilatant material which does not necessarily obey an associated flow law. The theoretical results indicate that the use of granular piles as a method of soil stabilization results in significant improvement in the load settlement behaviour of a foundation. /Author/TRRL/
