Der volle Inhalt der QuelleThe increase in the atmospheric CO2 concentration due to the combustion of the fossil resources and deforestation is the major environmental problems today. To store carbon and thus to decrease the concentration of CO2 emitted by human activity in the atmosphere, it would be necessary to be able to operate the carbon sinks located in the continental biosphere. The largest carbon surface reservoir of the continental biosphere is the soil, which stores 1500 Mt carbon. The potential of French soil to store carbon is currently being evaluated for the plowed horizon, i. E the first 30 cm. However, recent studies showed that a significant proportion of soil carbon is stored in horizons B and C. The precise role of soluble organic carbon or DOC (Dissolved Organic Carbon) in the stabilization and / or destabilization of carbon deep horizons is indispensable to adapt the methods of land management and cropping systems to increase the stock of carbon in soils. Despite abundant literature, studies on DOC are mainly limited to soils of forest ecosystems and especially in laboratory scale. The results were never confirmed on the ground. The overall objective of this thesis is to better define the proportion of soluble organic matter of different horizons of arable soil and indicate their main structural features. This work takes into account the importance of the mode of cultural practice and the impact of prolonged drought particularly in deep horizons. Different analytical techniques (spectrofluorimetry, chromatography size exclusion, pyrolysis GC / MS, 13C NMR) were used on waters collected at the lysimeter plates and porous candles but also HPO, TPH and HPI extracts, for characterizing the OM of deep horizons, while being based on existing work on surface water. The work showed that the OM of the deep horizons was characterized by low aromaticity, a lower molecular weight and by the presence of compound lignins types and terpenoids

Der volle Inhalt der QuelleIncreasing anthropogenic emissions of CO2 to the atmosphere are accelerating climate change. These emissions could be partially compensated by carbon fixation in the oceans, vegetation and soils. In particular, soils contain three times more carbon than the atmosphere, and therefore play a crucial role in climate regulation. It has been suggested that storing carbon in the deep layers of the soil, via rhizodeposition of plants, may be a useful avenue to pursue in order to mitigate climate change. We therefore conducted an experiment at CEREEP-Ecotron Ile-de-France to quantify the input and persistence of rhizodeposited carbon by plants using a continuous 13C-CO2 label. Two wheat varieties with contrasting root systems were planted in mesocosms and grown for a full growing season in a 13C-enriched atmosphere. Our objectives were to quantify the rooting-dependent flux of carbon from the atmosphere to the soil by isotopic tracing with 13C, and to measure its short-term persistence. The results showed that the old variety Plantahof rhizodeposited a larger amount of carbon than the more recent variety Nara, especially at depth. However, the carbon supplied to the soil by these two varieties led to similar amounts of organic C mineralization and priming effects. Thus, the total carbon balance was more related to the effect of soil depth than to the varieties used in the study. Furthermore, I carried out a meta-analysis of the distribution of enzymatic activities as a function of soil depth for hydrolases and oxidoreductases involved in the carbon, nitrogen and phosphorus cycle. The results of this analysis showed that the activity profiles depended very strongly on the way these activities were expressed, with activities mostly decreasing when expressed per soil mass, but remaining rather stable or even increasing with depth when expressed per unit microbial biomass. Taken together, these results show that considering the functioning of the entire soil column is essential to understand the dynamics of carbon in terrestrial ecosystems

Der volle Inhalt der QuelleThe study of the equilibrium of the lined tunnel is of big interest. From a mechanical point of view, it is a problem of complex interaction between two structures which have very different behaviour : the rock mass with the cavity on one hand and the lining on the other hand. The time dependent effects which appear in a rock mass are principally due to two phenomena which can be coupled : viscosity of the solid part ; diffusion of the intersitial fluid through the rock mass. We first present a bibliographical survey with the different stages of the study, design and realisation of a deep tunnel project. In the second part of this dissertation, we study the influence of loading history (the speed of the tunnel advancing and the instant of lining placement) on the equilibrium of a lined tunnel driven in a monophasic viscoplastic rock mass. A simplified method of dimensioning tunnels excavated in such media is developed. We also study the hydro-mechanical coupled effects on deep tunnels driven in isotherm saturated porous media having a poro-elastic or poro-elasto-plastic behaviour. An unidimensional analytical study reveals the influence of the mechanical loading history and the hydraulic boundary conditions at the tunnel wall. Numerical simulations of the tunnel front progress, at a given rate, are carried out for an axisymmetric 2D geometry. With the generalisation of the fictitious stress, the analytical study allows to localise the equilibrium point in the (wall convergence – stress applied on the wall) plane. These results allow to mke tunnel dimensioning computations with strain plane in biphasic media with more rigor

Der volle Inhalt der QuelleShallow geothermal energy is an energy that can help humanity to reach the goal of sustainable development. Ground-Coupled Heat Pump system is traditionally used to benefit this energy. As a main element of the system, ground heat exchanger performance directly influences its energy efficiency. The shallow ground heat exchangers are normally installed in soils, which show high heterogeneity of hydrothermal properties along the soil profiles. The main objective of this project is identifying how ground heat exchanger behaves in the soil. In summary, the following investigations were conducted: the first is introducing hydrothermal transfer in the numerical modeling of Borehole Heat Exchanger installed at a site in Alsace region (France); the second is identifying the factors influencing the performance of a shallow Borehole Heat Exchanger installed in soils; the third is conducting sensitive analysis of Thermal Response Tests for Borehole Heat Exchanger installed in soils; the fourth is identifying the performance difference of a numerical simulation model with Neumann and Dirichlet boundaries on the ground surface for a Horizontal Ground Heat Exchanger
