ABSTRACT: This paper examines the relations used to model stress variations for settlement calculations. It also presents an indirect means of determining the system parameters that act as surrogates for the elastic (or resilient) modulus, most notably via the falling weight deflectometer (FWD). The motivation for this contribution stems from the research findings associated with discrete element simulations, as well as observations from photoelasticity experiments that demonstrate the development of evolving, complex force chain networks in initially assumed, isotropic particulate materials. The motivation is further reinforced when examining geomorphology in conservation areas, which display nature's contribution to future foundation materials and aggregate deposits.


RÉSUMÉ: Cet article examine les relations simples utilisées pour modéliser les variations de contrainte dans les calculs de tassement. Il présente également une méthode indirecte de détermination des paramètres du système servant de substituts au module d'élasticité (ou de résilience), notamment grâce au déflectomètre à masse tombante (FWD). Cette contribution s'appuie sur les résultats de recherche issus de simulations par éléments discrets, ainsi que sur les observations issues d'expériences de photoélasticité, qui montrent clairement l'évolution de réseaux de chaînes de force complexes se développant dans des matériaux particulaires initialement isotropes. Cette motivation est renforcée par l'étude de l'évolution de la géomorphologie dans les zones de conservation, qui témoigne de la contribution de la nature aux futurs matériaux de fondation et dépôts de granulats.
