To better understand the salinity effect on the compaction behaviour of soil, standard Proctor compaction test was conducted on soil samples with different salinities. Matric suction and small-strain shear modulus,Gmax, were determined and pore size distribution was also investigated on samples staticallycompacted at different water contents. Resul...
In the European Union, most of the wastes from the building sector are composed of earths. Earth construction may be an interesting outlet for the re-use of these wastes, while meeting the challenge of circular economy: in particular, it involves low-embodied energy processes and earth material can be reused for building by end-of-life. Nonetheless...
Cette thèse s?inscrit dans le cadre du Projet National ARSCOP (« nouvelles Approches de Reconnaissance de Sols et de Conception des Ouvrages géotechniques à l'aide du Pressiomètre »). Elle a pour principal objectif le développement d'une nouvelle méthodologie de dimensionnement des fondations profondes sous chargement cyclique à partir du pressiomè...
In practice, the soils in shallow depth are usually subjected to the effect of wetting-drying cycles, leading to water content variations. As water content decreases, the dissolved salt starts to precipitate or crystallize, due to the saturation of salt in soil pore water. In reality, only dissolved salt has a significant effect on the thermo-hydro...
Le développement de la méthode du Deep Soil Mixing a permis d'élargir ses applications. Étant auparavant limitée aux applications d'amélioration des sols, la méthode s'applique aujourd'hui aux éléments structuraux et aux murs de retenue et d'étanchéité, comme par exemple, dans le cadre des travaux de renforcement des digues de Loire pour lutter con...

The difficulties, challenges and limitations faced in standard pressuremeter testing in the measurement of low soil deformations led a number of researchers to think about the possible modification of the equipment, and especially the replacement of the volumeter by a Hall Effect sensor. This article is a major contribution in this direction. It ma...
In the hydraulic binder domain, the presence of clay aggregates has been known for a long time to be harmful to hardened mortar or concrete material. However the deep soil mixing technique to reinforce dikes or soils for foundation mixes the existing soil with cement (CEMII or CEMIII). A better understanding of the interaction between anhydrous cem...

Each year hydraulic structures such as levees and earth dams are hit by disorders that can lead to their collapse. A dike reinforcement method such as the deep soil mixing gets interest for its reinforcement capacity at moderate cost. We report on the use of a non-destructive technique to effectively assess the proper achievement of these structure...
