Non-linear finite element analyses have intrinsic model and user factors that influence the results of the analyses. However, non-linear finite element analysis can provide a tool to assess safety using realistic descriptions of material behaviour with actual material properties. A realistic estimation of the existing safety and capacity of slender...
The hydraulic conductivity of saturated clays is commonly determined either directly by monitoring water flux or indirectly based on Terzaghi's consolidation equation. Similar results are generally obtained from the two methods, but sometimes a significant difference can be observed, in particular for expansive soils. In this study, the hydraulic c...
Mud pumping induced by repeated train passages is one of the most serious distresses not only for ballasted tracks but also for ballastless tracks. In this study both field and laboratory tests were performed to find out the main influencing factors and to further develop a new remediation method. Field observations showed that mud pumping in balla...
The reclamation of land filled with high water content dredged clays is an important geological and geo-environmental issue. When designing such reclaimed land, the yield behaviour during compression is of paramount importance because it conditions the compressibility of soil and thus the final ground settlement. Previous studies suggest a signific...
The behaviour of clayey soils is strongly correlated to their microstructure and evolution thereof. Microstructural investigations have contributed to understanding soil behaviour and have supported the development of multi-scale coupled models. One of the most accessible methods to characterise soil microstructure is mercury intrusion porosimetry,...

The water retention, compressibility and swelling properties of a pellet/powder bentonite mixture were investigated in the laboratory. The water retention capacity was determined under constant-volume condition using a specially designed cell allowing vapor exchange in all directions; suction controlled oedometer tests were carried out for the comp...
Les acteurs des laboratoires de recherche scientifique environnementale collectent régulièrement de nombreux échantillons qui sont ensuite analysés et stockés. Leur gestion sur le long terme s'inscrit dans une stratégie qu'il s'agit de définir puis de mettre en oeuvre via desoutils informatiques adaptés. Cet article présente cette stratégie, puis s...
