Abstract

Reducing uncertainty on the results of reliability analysis of earth fills using stochastic estimations Z. Mrabet' & A. Bouayecf ' University of Portsmouth School of Earth, Environmental & Physical Sciences,Portsmouth, UK ^ Laboratoire de Geomecanique, Vandoeuvre-les-Nancy, France Abstract This paper considers the uncertainties in soil parameters of earth fill structures, specifically their spatial variability. The use of random field theory will be detailed, in conjunction with the stochastic finite element method (SFEM), to describe and model the uncertainty in geotechnical properties of compacted soil masses. The paper focuses on the importance of conditional random fields that take into account supplementary data during the construction phase of earth fills. 1 Introduction The design of earth fill structures and theirs construction is based on using materials associated with properties that have a significant degree of uncertainty. These properties c
