Earth fill modelling with finite element method

Abstract

The objective of this study was to examine load-deformation characteristics at different fill layers of a high fill and to determine typical modeling parameters by using plate loading tests in a real construction site. The average value of the modulus of elasticity $E_{plaxis}$ was found to be 53 MN/$m^2$ and Poisson’s ratio was found to be 0.2 for the dense sand soil of the construction site. With proper compaction, load-deformation characteristics were found to be almost identical in different layers of the fill and very close to that of the natural soil.
