Abstract

In the mechanism analysis of foundation consolidation by using dynamic compaction, many kinds of non-linear conditions exist. This paper adopts large deformation on the relationship between strain and displacement. Non-linear governing equation of soil, based on finite element method, is established. Iterative calculation form is raised. Finally, non-linear numerical analysis is done to a calculation example. We not only obtain the changing regularity of soil displacement and stress during the acting time of dynamic compaction, but also achieve their contour maps after compaction.

Keywords: Dynamic compaction, non-linear, large deformation.
