Job description

Title of the PhD thesis:
Experimental and numerical study of the durability of geomaterials by coupled Thermo- Hydro-Mechanical and Geochemical (THM+geoC) approach applied to geotechnical structures.

The aim of the thesis is to lay the foundations for modeling the processes that cause the physico-chemical degradation of materials and their impact on the mechanical stability and hydraulic properties of structures. This PhD thesis aims to couple geochemistry and geotechnic. The aim is to develop an approach that is both numerical and experimental in order to couple the degradation of materials in their environment (geochemical approach) and the consequences of these degradations from the geotechnical point of view (loss of performance). It is clear that few studies link these two aspects, which are generally treated separately by two research communities. Indeed, much research has been conducted on the transport of pollutants in porous materials in relation to environmental problems. But the subject of reactive fluid transport, in a context of durability of earthen structures (for example embankments, dikes, grounds for foundations …) has not been much developed, except in the particular context of the geological disposal of radioactive waste. In this case, the fluids come into physico-chemical interaction with the porous matrix and cause a modification of the mechanical and hydraulic properties which impacts the service life or the integrity of the structure and can generate a risk situation (rupture, collapse…).
