Mechanical behavior of an unsaturated clayey silt: an experimental and constitutive modelling study
(2019-10)
Article
Accés obertThis paper reports an experimental study and subsequent constitutive modelling focused on the stress-strain and volumetric response during deviatoric stress application of a partially saturated clayey-silt. The material ... -
Mechanical behaviour of heavily compacted bentonite under high suction changes
(Institution of Civil Engineers (http://www.ice.org.uk/), 2003)
Article
Accés obertThe paper reports the results of an experimental study carried out on a bentonite compacted to a dry density of up to 1·7 Mg=m3, a high value for this type of soil. The soil fabric has been studied using a variety of ... -
Modeling soil-facing interface interaction with continuum element methodology
(2022-03)
Article
Accés obertSoil-facing mechanical interactions play an important role in the behaviour of earth retaining walls. Generally, numerical analysis of earth retaining structures requires the use of interface elements between dissimilar ... -
Modelling 3D mechanical interfaces with continuum elements
(2013)
Text en actes de congrés
Accés obertThis document presents preliminary results of FEM-numerical analysis of soil-reinforcement pullout tests. The numerical model has been developed with CODE_BRIGHT and assuming the interfaces as continuum materials. The ... -
Monitoring and modeling of slope response to climatic changes
(CRC Press, 2008)
Text en actes de congrés
Accés restringit per política de l'editorialShallow slides are often triggered by climate effects. An understanding of the slope failure conditions and effective remedial measures can be achieved by comprehensive field monitoring of climatic and hydrologic changes ... -
Monitoring of a full-scale embankment experiment regarding soil–vegetation–atmosphere interactions
(2018-06)
Article
Accés obertSlope mass-wasting like shallow slides are mostly triggered by climate effects, such as rainfall, and soil–vegetation–atmosphere (SVA) interactions play a key role. SVA interactions are studied by a full-scale embankment ... -
Monitoring the role of soil hydrologic conditions and rainfall for the triggering of torrential flows in the Rebaixader catchment (Central Pyrenees, Spain)
(2023-02)
Article
Accés obertTorrential flows (debris flows and debris floods) are mainly triggered by precipitation and soil hydrological processes. Most early warning systems in torrential catchments are rainfall-based. However, this approach can ... -
New challenges in experimental unsaturated soil mechanics. Experimental upscaling of an engineered gas-permeable seal
(EDP Sciences, 2023)
Article
Accés obertAn example of upscaling phenomena with experimental techniques is presented and discussed within an engineered seal concept for a future deep geological repository for low and intermediate radioactive waste mainly produced ... -
Numerical analysis of an instrumented steel reinforced soil wall
(2014-02-20)
Article
Accés restringit per política de l'editorialThe paper describes the results and lessons learned using a PLAXIS finite element method (FEM) model to simulate quantitative performance features of the Minnow Creek steel strip reinforced soil wall structure located in ... -
Numerical analysis of the behaviour of embankments constructed with expansive soils
(Taylor & Francis, 2010)
Text en actes de congrés
Accés restringit per política de l'editorialThe recent advances made in modern Unsaturated Soil Mechanics have permitted the development of new analysis methods for the prediction of the behaviour of embankments and other earth structures subject to changes in ... -
Numerical study of the influence of foundation compressibility and reinforcement stiffness on the behaviour of reinforced soil walls
(2014-07-01)
Article
Accés restringit per política de l'editorialMost geosynthetic and metallic reinforced soil walls are designed assuming that the wall foundation is rigid and/or does not influence the magnitude and distribution of reinforcement loads under operational conditions. ... -
Numerical study of the use of actively-tensioned polymeric strips for reinforced soil walls
(Institution of Civil Engineers (ICE), 2015)
Text en actes de congrés
Accés restringit per política de l'editorialPolymeric strip reinforced soil walls require a practical method to fix the reinforcement tail-ends in the soil backfill during construction to ensure adequate anchorage and to avoid any slack along the linear reinforcement ... -
One-dimensional cracking model in clayey soils
(2013)
Text en actes de congrés
Accés restringit per política de l'editorialIt is difficult to formulate a general model to capture cracking initiation and evolution, because there are multiple factors that influence these processes. In order to simplify the evaluation and get more insight on the ... -
Parameter calibration for hydro-mechanical modelling using numerical simulations of test results
(Taylor & Francis, 2010)
Text en actes de congrés
Accés restringit per política de l'editorialThe paper reports an experimental study and parameter calibration exercise centred on the hydro-mechanical response of an unsaturated soil. The study benefits from compacted silt samples retrieved from a fully instrumented ... -
