In situ temperature monitoring in an organic-waste landfill cell / Abdelmalek Bouazza in Journal of geotechnical and geoenvironmental engineering, Vol. 137 N° 12 (Décembre 2011) 

Public ISBD [article]  in Journal of geotechnical and geoenvironmental engineering > Vol. 137 N° 12 (Décembre 2011) . - pp. 1286-1289 Titre : In situ temperature monitoring in an organic-waste landfill cell Type de document : texte imprimé Auteurs : Abdelmalek Bouazza, Auteur ; Hani Nahlawi, Auteur ; Martin Aylward, Auteur Année de publication : 2012 Article en page(s) : pp. 1286-1289 Note générale : Géotechnique Langues : Anglais (eng) Mots-clés : Landfill  Organic  waste  Monitoring  Temperature Résumé : This paper presents the results of a temperature-monitoring program in an organic-waste landfill cell under normal operating conditions. The aim of the program was to capture the temporal evolution of temperature at various locations within the cell. Temperatures were measured at two levels within the central body of the cell over a period of 20 months. The results obtained over that period of time indicate that the temperatures increased within the first few weeks, then decreased to a stable value after a few months. The peak temperatures near the base of the landfill cell (2 m above base liner) averaged 60°C at the start of the monitoring program and leveled off to 53°C after 8 months. The peak temperatures in the second lift (4 m above base liner) averaged 57°C and leveled off to 55°C after 13 months. The temperatures taken close to the base of the cell indicate that the lining system is subjected to high temperatures, outside the range of temperature typically considered during testing and design. This observation highlights the importance of considering the possible impact of the changes in temperature on the performance of the different liner system components from both the hydraulic view point and durability.

Influence of cyclic stress pulse shapes on filtration behavior of railway subballast / Asadul Haque in Journal of geotechnical and geoenvironmental engineering, Vol. 138 N° 2 (Fevrier 2012) 

Public ISBD [article]  in Journal of geotechnical and geoenvironmental engineering > Vol. 138 N° 2 (Fevrier 2012) . - pp. 230-235 Titre : Influence of cyclic stress pulse shapes on filtration behavior of railway subballast Type de document : texte imprimé Auteurs : Asadul Haque, Auteur ; Abdelmalek Bouazza, Auteur Année de publication : 2012 Article en page(s) : pp. 230-235 Note générale : géotechnique Langues : Anglais (eng) Mots-clés : Cyclic  load  Stress  pulse  Sub-ballast  Laboratory  tests Résumé : Filtration behavior of subballast materials subjected to different cyclic stress pulse shapes at frequencies of 5 Hz and 10 Hz was investigated in the laboratory. Clayey silt was used as a base soil while graded crushed basalt was used as a filter. Rectangular, sinusoidal, and triangular cyclic stress pulse shapes having a stress range of 70–140 kPa were investigated for a piping ratio of 9. Turbidity, permeability, and change of pore water pressure within base soil were recorded over time as the number of stress pulse cycles increased. Results show that triangular and sinusoidal cyclic stress pulse shapes have a similar effect on the filtration behavior while the rectangular cyclic pulse shape had a slightly higher effect than triangular and sinusoidal stress pulse shapes. Based on this study, a piping ratio of 9 was found to be satisfactory for all cyclic stress pulse shapes at 5 Hz.

Numerical characterization of advective gas flow through GM/GCL composite liners having a circular defect in the geomembrane / Hossam M. Abuel-Naga in Journal of geotechnical and geoenvironmental engineering, Vol. 135 N° 11 (Novembre 2009)

Abuel-Naga, Auteur ; Abdelmalek Bouazza, Auteur Année de publication : 2009 Article en page(s) : pp. 1661–1671 Note générale : Geotechnical and geoenvironmental engineering Langues : Anglais (eng) Mots-clés : Gas  flowLeakageGeomembranesDefectsLandfillsClay  liners Résumé : Numerical experiments were conducted to understand the effect of geometric and transport characteristics of a geomembrane-geosynthetic clay liner (GM/GCL) composite liner on gas leakage rate through a circular defect in the geomembrane (GM). The originality of the approach proposed in this paper rests on the use of a new conceptual two-layered system for modeling of GM/GCL composite liners where the interface zone between the GM and geosynthetic clay liner (GCL) has been merged with the GCL cover geotextile and handled as one layer; the GCL bentonite layer was considered the second layer. The role of the carrier geotextile layer was ignored since it can be considered as a no pressure loss layer. Analysis of numerical simulation results shows the existence of a constitutive leakage flow surface which enables evaluation of the leakage flow state for different geometric and transport properties of GM/GCL composite liners. Furthermore, the determined surface was also exploited to evaluate gas leakage rates under the framework of the Forchheimer’s analytical solution. The gas leakage rate predictions were found to be in good agreement with experimental results obtained at different GCL moisture content.
