Testo completoThe excavation of underground galleries generally results in a zone damaged by fractures. In the context of the storage of radioactive waste in deep clay layers, this network of fractures desaturates the host rock and causes it to lose its confinement properties (very low permeability, good mechanical strength). This thesis focuses on the Callovo-Oxfordian claystone (COx), a geological formation chosen in France (Bure, Meuse/Haute-Marne) for its potential as a containment barrier for radioactive waste. Using an experimental approach, the impact of crack propagation and self-sealing on the water and gas permeability of the COx claystone was studied. Self-sealing tests were carried out on cylindrical specimens artificially fractured under X-ray tomography, under different orientations (parallel and perpendicular to the bedding plane) and temperatures, with different calcite contents, different opening widths of the initial fracture, and with the injection of different fluids such as water and gas. The objective being to better understand the impact of these different factors on the self-sealing process of the COx claystone (changes in permeability and fracture closure). Furthermore, fracturing tests with measurement of gas permeability were also carried out for the two orientations in order to study the impact of microcracking damage on the hydraulic properties of the COx claystone. It has been observed that the mineralogical composition of the claystone plays a determining role in the effectiveness of self-sealing. High calcite content, combined with low clay content, has been identified as a limiting factor, thereby compromising the rock's ability to self-seal effectively. To guarantee effective sealing, it is necessary that the calcite content remains below 40%. In general, the self-sealing process is rapid at the start of the test and then stabilizes after a month. The water permeability of the samples is partially restored (~10-18-10-19 m²) compared to the initial permeability of healthy claystone (i.e. without fracture) (~10-20- 10-21 m²) and the closure of the fracture is almost complete. Furthermore, the self-sealing process appears to be equally effective for both parallel and perpendicular orientations. The impact of temperature on the self-sealing process has not been clearly demonstrated. Regarding the simultaneous injection of inert gas and water, our study demonstrated a retarding effect on the reduction of water permeability, mainly due to gas-induced desaturation. Despite this delay, the self-sealing process proved effective, inducing a significant reduction in permeability. The fracturing tests (triaxial compression tests) showed that the gas permeability gradually decreases for both orientations with increasing deviatoric stress, illustrating the closure of the initial cracks due to the axial compression of the samples. For higher deviatoric stresses, a significant increase in gas permeability is observed near the dilatancy threshold, particularly in samples oriented parallel to the bedding plane. This suggests a close link between the opening of microcracks and the increase in permeability

Testo completoIn the hygroscopic range of wood and at low temperatures, internal transfers of water in gaseous phase and bound water are made by diffusion. The purpose of this research is to specify a methodology which allows the determination of diffusion coefficients, characteristic of the two transfers. Three experimental devices have been used : a Wicke and Kallenbach diffusion cell, a vaporimeter and a double hygrometric cell. The study of the same samples with the three devices makes up an original work in the diffusionnal transfer's field of an adsorbable solute in a porous medium. The knowledge of these results are not only interesting for the modelisation of diffusionnal transfers of water into wood and wood composites, but also the suggested methodology can be applied for every gaseous adsorbable solute on a microporous solid , as an adsorbent or a catalyst

Testo completoThis work aims at a better knowledge of the simultaneous transfer of water and solute for a better dimensioning of the sealing systems. To follow this transfer in real time and in continuous, we used the TDR probes. The experimental device developed allows the measurement of the moisture and electric conductivity profiles during infiltration. This measurement of the soil water content and the soil electric conductivity is necessary to evaluate the leakage potential of a sealing barrier. We carried out a series of infiltration tests in columns on: a clayey sand, a clay (of Gault), two alluvia layers separate by a geosynthetic clay liner (GCL) and columns containing a drainage material. The study of the water and the leachates infiltration in the clayey sand under a null hydraulic head shows that the compacted soil saturation process is done by the combination of a phenomenon of convection and of diffusion. The electric conductivity profiles analysis shows that the solute transport is also done by dispersion and convection. We could note that the infiltration of a liquid does not depend only on the soil type, but also depends on the type of liquid and of the chemical elements which contains. The impact of the leachate on the soil results from the reduction of the transit time and of the equilibrium water content i. E. The quantity of water which the soil can retain

Testo completoOne of the conditions that has to fulfill by a barrier in a waste disposal site is to insure a coefficient of permeability less than l0(exp)-9m/s. The measurement of this permeability poses a lot of difficulties to which hydric transfer in unsaturated soils should be able to resolve. In this framework, the experimental results related to study of water transfer by infiltration in a compact unsaturated fine soil under a well defined initial and boundary conditions are presented. Firstly, a parametric study has been performed on the Givors silt; infiltration tests have been realized under various conditions. This study allowed the identification of the different parameters that can influence the hydric transfer in a unsaturated soil and to define an experimental procedure for field measurement of coefficient of permeability. Secondly, this parametric study was completed with a series of infiltration tests realized on a sail column,225mm high, for which the analysis of the hydric profile and suction was possible with the use of a new experimental device. A second procedure for permeability coefficient measurement of in-situ was proposed. The instantaneous profile method has been applied on results of infiltration tests on the soil column,225mm high, to establish the relationship between hydraulic conductivity and volumic water content or suction. Mualem and Van Genuchten model were also applied and verified
