Environmental geomechanics by B. A Schrefler( )

11 editions published between 2010 and 2013 in English and held by 328 WorldCat member libraries worldwide

This title covers topics that are of increasing importance in engineering practice: natural hazards, pollution and environmental protection through good practice. The first part of the book deals with natural risk factors, of both natural and human origin, that should be borne in mind. The second part is devoted to pollution and polluted sites and their repercussions, a facet of growing significance given the increasing reclamation of land from abandoned industrial sites for urban development over the last 20 years. Different types of oil pollution and methods of decontamination are described, followed by a discussion of waste management and detailed coverage of confinement liners used in surface waste disposal
Clays in natural and engineered barriers for radioactive waste confinement by Conference on 'Clays in Natural and Engineered Barriers for Radioactive Waste Confinement'( )

Comportement hydromécanique d'un loess naturel by José Muñoz-Castelblanco( )

1 edition published in 2011 in French and held by 2 WorldCat member libraries worldwide

The hydromechanical behaviour of an unsaturated natural loess from Northern France has been studied. Collapse-on-wetting phenomena under constant external load are observed in the in-situ conditions, related to some stability problems detected on the loess foundations of the high speed train line that links Paris to Brussels. A new triaxial apparatus with complete local monitoring of unsaturated properties (strains, water content and suction) of this loess has been developed. The water retention curve of loess, obtained by using an in-house constructed high capacity tensiometer and the filter paper method, shows a special behaviour, with a non-hysteresis zone detected around the natural hydric state bordered by two hysteresis loops at the dry and wet sides of the curve. Further analysis of the water retention curve and of the hysteresis phenomena were conducted by means of a microstructure study made by mercury intrusion porosimetry and scanning electron microscope observations. The complex structure of loess is highlighted, composed by a metastable arrangement of dry silt grains (possibly related to carbonate re-crystallisation) and a heterogeneously distributed clay fraction. The hydromechanical behaviour study includes the evaluation of the collapse sensibility of loess at stress states close to the in-situ one, by a series of suction-monitored oedometer tests performed at different constant strain rates (CSR tests). A maximum of collapse and a time-dependent behaviour of loess were observed. A triaxial testing programme at different water contents with suction measurement, allowed to obtain the yield surface of loess in a q/p diagram, and the water content and suction evolution upon loading and to confirm the suction hardening in this material
Etude des mécanismes de rétention et de transfert des polluants non miscibles dans les sols fins non saturés by Pascale Alzoghbi-Massaad( Book )

2 editions published between 2001 and 2006 in French and held by 2 WorldCat member libraries worldwide

Les préoccupations accrues liées aux problèmes des sols pollués par les hydrocarbures de sources anthropiques (transport routier et fluvial, effluents industriels, extraction et transport du pétrole, chauffage) ou naturelles (feux de forêt), ont conduit à s'intéresser à ce type de pollution. Lorsqu'un produit pétrolier est malencontreusement déversé à la surface du sol, il s'infiltre en traversant d'abord la zone non saturée pour atteindre la zone saturée, affectant ainsi la qualité de la nappe phréatique. Par évaporation certains composants volatiles peuvent également polluer l'air. Le but de ce travail est d'étudier les mécanismes de rétention et du transfert d'un polluant hydrocarboné dans la zone non saturée, qui constitue l'interface entre l'atmosphère et la nappe phréatique. L'étude est réalisée sur un limon des Plateaux de l'Est parisien (limon de Jossigny) compacté, le polluant utilisé étant un hydrocarbure désaromatisé(Soltrol 170). Des cellules de rétention triphasiques originales ont été développées afin de permettre la détermination de la courbe de rétention en huile des échantillons de limon compacté non saturé, ainsi que l'étude du transfert de l'hydrocarbure lorsque trois fluides coexistent au sein de l'espace poreux du sol (eau /air /huile). Cette étude a été complétée par une étude microstructurale qui a mis en évidence l'augmentation de la macroporosité due à l'infiltration du polluant. Des essais de résistance à la compression simple nous ont permis d'identifier les trois mécanismes d'interaction possibles entre le polluant et le sol non saturé. A faibles densité et degré de saturation, le polluant peut se trouver en contact direct avec les minéraux argileux, ce qui engendre un raidissement du matériau. A une densité moyenne, c'est la capillarité qui caractérise les interactions entre fluides. A forte densité, le comportement du sol est conditionné par le piégeage de l'air. Nous avons réalisé une analyse numérique à l'aide d'un code calcul développé au CERMES(UDAM), pour simuler le transfert du polluant dans un massif de sol, et ceci grâce à l'intégration des paramètres nécessaires déterminés par les essais expérimentaux. Cette approche numérique a montré que le débit joue un rôle important sur le transfert du polluant dans les sols

Comportement thermo-hydro-mécanique et microstructure de l'argilite du Callovo-Oxfordien by Hamza Menaceur( )

1 edition published in 2014 in French and held by 2 WorldCat member libraries worldwide

The development of nuclear energy in recent years requires safe solutions for the storage of radioactive waste. A solution proposed for high activity radioactive waste is the storage indeep low permeability geological formations such as claystones. In this perspective, Andra, the French agency for the management of radioactive wastes, supported investigations on theshort and long term behaviour of the Callovo-Oxfordian (COx) claystone, considered as apotential host rock in France. In this framework, a microscopic and macroscopic experimental study on the thermo-hydro-mechanical behaviour of COx claystone was carried out. In this work, a microstructure investigation of the water retention properties of the Cox claystone was performed. The water retention properties were determined by controlling suction through the vapour phase, with also the monitoring of volume changes and changes indegree of saturation as a function of suction along the drying and wetting paths. The study was completed by a microstructure investigation based on the use of mercury intrusion porosimetry on freeze-dried specimens. It was observed that the concepts governing the hydration of smectites appeared useful to better understand the effects of changes in water content and suction on the microstructure of COx claystone. In a second step, the compression-swelling behaviour of the COx claystone was related to micro structure features by performing high pressure oedometer compression tests and byrunning mercury intrusion porosimetry tests and scanning electron microscope observationson specimens submitted to compression and stress release. The results obtained showed that the potential of swelling was linked to the density of cracks generated during compression. The thermo-mechanical behaviour of fully saturated COx claystone specimens was investigated from shear and drained heating tests using a hollow cylinder triaxial device specially developed for low permeability materials. The shear tests at 25°C evidenced lowershear strength on specimens with higher porosity. The preliminary results obtained at 80°Cevidenced a more ductile response, with slightly smaller shear strength and little changes of the elastic parameters at elevated temperature. Drained isotropic heating tests confirmed thecontracting volumetric plastic behaviour of the COx argillite, similar to normally consolidated clays. The effect of thermal pressurisation of the pore water on a specimen with a pre-existingshear plan was investigated. The results showed that undrained heating under shear stress decreased the effective stress, bringing back the sheared specimen to failure. The self-sealing properties of COx claystone at 25 and 80°C were investigated by conducting steady state permeability tests on sheared specimens at various stages. The results showed that the overall permeability of the sheared specimen at 25 and 80°C was comparable to that before shearing, confirming the good self-sealing properties of COx claystone
