“…The model was initially proposed by Kondner and Zelasko (1963) and was subsequently presented on an incremental basis by Duncan and Chan (1970). It assumes that the stress-strain curves of soil can approximate a hyperbola (Lamas et al, 2011).…”

“…To determine the stress-strain states generated within embankments due to applied loads and gravity, researchers have developed analytical and empirical methods (Lamas et al, 2011;Standing et al, 2020) that enable the design and enforcement of the project within the admissible parameters of durability and deformability. Moreover, modelling techniques have been used to develop constitutive models (Feng et al, 2020;Jiang et al, 2020;Li et al, 2021).…”

Numerical modeling is a powerful tool to determine the stress-strain relationships of structures. However, for a reliable application, physical and mathematical models must be calibrated and validated. This paper presents an overview of numerical calibration through the finite element method and plate-load tests in an embankment. Additionally, an analysis of the constitutive models used in soils is performed, and the elastic-plastic constitutive model of Mohr-Coulomb was selected since it is the best suited for this study. The results from three test areas within a refinery project that the Cuban government undertook in the province of Cienfuegos are used. The numerical model used in this study was calibrated by means of the error theory and the non-parametric hypothesis tests from Mann-Whitney U. From the practical point of view, this study gives two procedures to calibrate the numerical model with experimental results.

“…Les marnes se rencontrent dans de nombreux pays dans le monde parmi lesquels figurent la Grèce (Anagnostopoulos et al, 1991 ;Kavvadas et al, 1993), l'Italie (Jamiolkowski et al, 1995 ;Burland et al, 1996), la France (Gaudin, 1972 ;Gaudin et al, 1981 ;Tillard-Ngan et al, 1993 ;Pejon et al, 1997 ;Gaudin et Serratrice, 1998 ;Maquaire et al, 2003 ;Raynaud et al, 2008), l'Espagne (Serrano et al, 1981 ;El Amrani et Chacon, 1996 ;Lamas et al, 2011), le Portugal (Alonso et al, 2010), le Maroc (Ejjaaouani et al, 2013 ;Mouhssine et al, 2015) et l'Algérie (Djedid et al, 2001 ;Bekkouche et al, 2002 ;Derriche et Cheikh-Lounis, 2004 ;Boudlal et al, 2014) pour ne citer que quelques pays du pourtour méditerranéen et pour les aspects comportementaux de ces terrains. En pratique, les géotechniciens se trouvent souvent confrontés à des terrains dont le comportement est intermédiaire entre celui des sols et des roches et qui sont de ce fait difficiles à traiter avec les approches classiques.…”

-Diverses illustrations du comportement mécanique des marnes sont présentées sur la base d'exemples de résultats d'essais de laboratoire. Les marnes ont été testées dans leur état naturel au cours de programmes expérimentaux réalisés dans le cadre des reconnaissances géotechniques de massifs marneux pour des projets d'ouvrages en France. Les illustrations s'adressent à la grande variété des marnes par niveaux de difficultés expérimentales croissantes, en allant des marnes homogènes tendres vers des terrains fissurés ou altérés. Les premiers exemples concernent des marnes du point de vue de leur déformabilité, leur résistance et leur caractère isotrope ou anisotrope. Des exemples sont consacrés ensuite au comportement de marnes plus ou moins indurées, puis des marnes fissurées et des marnes altérées. Les programmes expérimentaux reposent essentiellement sur des essais triaxiaux qui sont réalisés dans une gamme étendue de pressions (0-10 MPa), ce qui permet de mettre en relief les différents aspects des comportements observés.
