Full textLime and/or cement stabilization is a common solution for improving the mechanical performance of fine soils. Treatment limits the shrinkage and swelling effect of clayey soils. However, while numerous laboratory studies have been carried out on treated materials, little is known about the in situ performance of such stabilised materials several years after construction, and very few studies are available, especially in the case of stabilised expansive soils. As a result, existing methods and procedures are generally unable to assess the alteration caused by the environmental conditions of a treated soil. This thesis addresses these issues by studying an experimental embankment at Héricourt (France). Built in 2010 as a part of the ANR TerDOUEST project, this embankment was built with a highly plastic clayey soil. The clay was treated with lime and/or cement upon construction. An initial assessment of the state of the backfill was carried out 11 years after construction of the structure, with horizontal and vertical corings. The hydromechanical characterisation of the treated clay was carried out with multiple oedometer tests. The compressibility of the material sampled by horizontal coring was determined, making it possible to assess changes in the mechanical behaviour of the treated soil as a function of its proximity to the edge of the embankment. The results showed that the materials located in the internal part of the embankment have a mechanical behaviour similar to that of the soil treated in the laboratory after a 180-day curing time at constant moisture content. On the other hand, a gradual deterioration of the mechanical properties of the material was observed as it approached the outer part of the embankment. The mechanical properties of the materials taken from the outer part were equivalent to those of the untreated soil. The microstructure (mercury intrusion porosimetry, scanning electron microscopy), chemical composition (thermogravimetric analysis, X-ray fluorescence) and mineralogical composition (X-ray diffraction) of the treated soil were studied in order to understand the environmental conditions responsible for the deterioration observed at the edges. Leaching from the treatment was identified as being partly responsible for the decrease in mechanical performance measured at the edge of the structure. Mineralogical transformations, such as the formation of calcite in the first few metres of the backfill, also highlighted an alteration of the hydromechanical behaviour through carbonation of the cement phases. The role of wetting and drying periods in the mechanical weathering of the treated soil was also studied. Specimens from the inner part of the structure were subjected to wetting and drying cycles of various suctions ranging from 0 to 95 MPa. The results showed that drying and wetting cycles have a major impact on the long-term performance of treated soils above a certain suction amplitude. The degradation process is mainly a consequence of cement bond failure rather than other physico-chemical processes such as calcium leaching or carbonation. This study allowed a mechanical quantification of the weathering of treated clay taken from an experimental structure. Leaching and carbonation during treatment were identified as being responsible for the deterioration in mechanical performance in the external part of the structure. The study of the treated material subjected to hydric cycles allowed to quantify their impact on mechanical behaviour, while determining the mechanisms by which the effects of the treatment were altered

Full textLand take and the associated environmental issues (heat islands, flooding, biodiversity degradation) have become a major issue in urban planning and development. The objective of this thesis is to propose an approach to characterise urban soils based on the analysis of their historical trajectory of land use, considering that the land use successions and the associated human practices determine the physico-chemical properties of soils. To do this, a scientific approach based on three complementary approaches was carried out to achieve an operational methodological proposal for predictive mapping of urban soil properties. The first approach is cartographic and documentary, and aims to better characterise the historical trajectories of urban soils and thus to better understand all of the human practices that the soils have undergone over time. It turns out that twenty historical trajectories are sufficient to describe the majority of the surface area of an urban unit. Moreover, the majority of historical trajectories represent land use successions composed of a maximum of one or two land uses, showing a low dynamic of land use changes and practices over time. The second approach is a field approach aimed at characterising the impact of three historical trajectories representative of urban soils on the physico-chemical properties of soils. It highlights the link between the historical trajectory of a soil and its physical and chemical properties. The impact of human practices on soil properties also appears to be dependent on the intensity of the practices carried out on the soil. These links, which are still underdeveloped, could be highlighted by the development of a new concept: the "anthroposequence". The last approach is an experimental approach that helps to characterise the pedogenetic processes involved during these historical trajectories and to describe the evolution of physico-chemical properties over time. It shows that the individual effects of practices can be contrary to the effect resulting from the whole of these practices. Moreover, the pedogenetic processes put forward during these experiments reflect the reality of the field, thus reinforcing the proposed experimental method. Thus, these three methodological approaches were finally discussed in order to transcribe the results obtained into "simple" rules allowing the cartographic prediction of soil types and certain agronomic parameters in urban environments through the knowledge of historical trajectories

Full textIn order to clean up polycyclic aromatic hydrocarbon (PAH) contaminated soils, various techniques have been developed during the last decades, but their impact on soil functions was rarely considered. The objective of this study was to assess the impact of chemical oxidation treatments on different physico-chemical and biological parameters of PAH contaminated soil and to propose solutions to improve the biological functioning of oxidized soil. Various laboratory and field experiments have shown that the efficiency of chemical oxidation reactions (Fenton reaction and activated persulfate) on PAH concentrations depended on pollutant availability and soil physico-chemical properties. Besides, intense acidification processes have been observed on uncarbonated soil with a strong impact on soil physico-chemical and biological parameters. Moreover, this alteration was higher with activated persulfate treatment, leading to the loss of trace metals in water percolation. In the strongly acidified soil, the input of materials, suitable for pH increase, resulted in the restoration of biological activities and soil capacity to support vegetation. The association of chemical oxidation treatment and restoration techniques could present a good mean for soil rehabilitation. Finally, an index, which aimed to represent soil conditions based on the weight given to different parameters, was proposed and was used to evaluate changes induced by oxidation treatments and restoration techniques
